What is the mass of a sample of NH3 containing 3. 80 × 10^24 molecules of NH3?
Answers
Answer:
107g
Explanation:
First convert the number of molecules to moles using avogadro's number.
There are 6.02 x 10^23 molecules in 1 mol.
3.8 x 10^24 molecules NH3 ÷ 6.02 x 10^23 molecules / mol
= 6.31 mol NH3
Now that we have moles of NH3 we can multiply it by NH3's molecular mass.
NH3 molecular mass = Mass of N + Mass of H x 3
14.007g/mol + 1.008g/mol * 3
= 17.031 g NH3/ mol
6.31 mol NH3 * 17.031 g NH3 / mol
= 107g NH3

Answers
The concentration of the HNO3 solution is 5.63 x 10^-2 M.
How can we calculate the concentration of HNO3?First, we need to find the number of moles of NaOH used in the titration:
0.225 M x 0.020 L = 0.0045 moles of NaOH
Since NaOH and HNO3 react in a 1:1 molar ratio, this means that there were also 0.0045 moles of HNO3 present in the original solution.
When 30.00 mL of the HNO3 solution is added to the mixture, the total volume becomes:
50.00 mL + 30.00 mL = 80.00 mL
Therefore, the concentration of the HNO3 solution can be calculated as follows:
0.0045 moles / 0.080 L = 0.05625 M or 5.63 x 10^-2 M
Therefore, the concentration of the HNO3 solution is 5.63 x 10^-2 M.

To see how much sugar we could add until it can be dissolved anymore. what effect would the sugar have on the temperature of the water in the reaction? if the temperature of the water were to be increased, then more sugar would be able to dissolve, because warm solution holds more solute than cold solution.
Answers
The effect of adding sugar to water is an increase in the temperature of the water. When sugar dissolves in water, it is an exothermic process, meaning it releases heat. Therefore, the temperature of the water would increase.
When sugar dissolves in water, the sugar molecules separate and become surrounded by water molecules through a process called hydration. This process is exothermic, meaning it releases energy in the form of heat. As a result, the temperature of the water increases.
The increase in temperature has an impact on the solubility of the sugar. Generally, increasing the temperature of a solvent, such as water, allows it to dissolve more solute. In the case of sugar and water, warmer water can hold more sugar in solution compared to cold water. This is because the increased temperature provides more kinetic energy to the water molecules, allowing them to break the intermolecular forces between the sugar molecules and facilitate their dispersal in the water.
Therefore, if the temperature of the water is increased, more sugar would be able to dissolve until the point of saturation is reached, where no more sugar can be dissolved at that temperature.

C. At what rate does the sphere (a) emit and (b) absorb thermal radiation? (c) What is the sphere's net rate of energy exchange? (a) Number (b) Number Units Units
Answers
a) The sphere emits thermal radiation at a rate of 139.75 Watts.
b) The sphere absorbs thermal radiation at a rate of 37.66 Watts.
c) The sphere's net rate of energy exchange is 102.09 Watts.
What are the rates of thermal radiation emission, absorption, and net energy exchange for the sphere?To calculate the rates of thermal radiation emission and absorption, we can use the Stefan-Boltzmann law, which states that the rate of thermal radiation emitted or absorbed by an object is proportional to its surface area, temperature, and the Stefan-Boltzmann constant.
a) The rate of thermal radiation emitted by the sphere can be calculated using the formula:
Emitting Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(temperature^4 - environment\ temperature^4\))
Plugging in the given values:
Emitting Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((32.2 + 273.15)^4 - (82.9 + 273.15)^4)\)
Emitting Rate ≈ 139.75 Watts
b) The rate of thermal radiation absorbed by the sphere can be calculated in a similar way but using the environment temperature as the object's temperature:
Absorbing Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(environment\ temperature^4 - temperature^4\))
Plugging in the given values:
Absorbing Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((82.9 + 273.15)^4 - (32.2 + 273.15)^4)\)
Absorbing Rate ≈ 37.66 Watts
c) The net rate of energy exchange is the difference between the emitting rate and the absorbing rate:
Net Rate = Emitting Rate - Absorbing Rate
Net Rate = 139.75 Watts - 37.66 Watts
Net Rate ≈ 102.09 Watts
Therefore, the sphere emits thermal radiation at a rate of 139.75 Watts, absorbs thermal radiation at a rate of 37.66 Watts, and has a net rate of energy exchange of 102.09 Watts.
Note: The units for all the rates are Watts.

Question 5 Not yet answered Marked out of 2 Flag question An aqueous solution of CaCl2 (molar mass = 110.98 g/mol) that is 0.866 molal has a density of 1.05 g/mL. Calculate the Morality (M) of NaCl that is isotonic with this solution. O A. 1.72 OB. 1.24 O C. 2.49 O D. 0.830
Answers
The molarity (M) of NaCl that is isotonic with the given CaCl2 solution is 1.72 M.
To calculate the molarity (M) of NaCl that is isotonic with the given CaCl2 solution, we need to consider the relationship between molality (m), density (d), and molar mass (M) of a solution. The formula to calculate molality is:
molality (m) = moles of solute / mass of solvent in kg
From the given information, we know that the molality of the CaCl2 solution is 0.866 molal. Since molality is defined as moles of solute per kilogram of solvent, we can calculate the mass of solvent using the formula:
mass of solvent = (moles of solute / molality) in kg
Given that the molar mass of CaCl2 is 110.98 g/mol and the density of the solution is 1.05 g/mL, we can determine the mass of solvent using the density:
mass of solvent = volume of solution × density
By rearranging the equation, we find:
volume of solution = mass of solvent / density
Substituting the given values, we get:
volume of solution = (moles of solute / molality) in kg / density
Now, we can calculate the volume of solution, which will be the same as the volume of solvent, as we assume ideal behavior and no significant volume change upon dissolution.
Once we know the volume of solvent, we can calculate the moles of NaCl required to make an isotonic solution using the same volume of solvent. Since isotonic solutions have the same osmotic pressure, the number of moles of solute particles should be the same. As CaCl2 dissociates into three particles (one Ca2+ ion and two Cl- ions) and NaCl dissociates into two particles (one Na+ ion and one Cl- ion), we can set up the following equation:
(0.866 molal of CaCl2) × (3 particles) = (Molarity of NaCl) × (2 particles)
Simplifying the equation, we find:
0.866 × 3 = Molarity of NaCl
Solving for the molarity of NaCl, we get:
Molarity of NaCl = 1.72 M

Answers
The most appropriate definition for NH3 in the given equation is Bronsted-Lowry base, as it accepts a proton from water to form NH4+ and OH-.
The definition that applies to the compound NH3 in the given chemical equation is Bronsted-Lowry base. The Bronsted-Lowry acid-base theory defines an acid as a substance that donates a proton (H+) and a base as a substance that accepts a proton.
In the equation NH3(aq) + H2O(l) → NH4(aq) + OH-(aq), NH3 (ammonia) acts as a base because it accepts a proton (H+) from water, which acts as an acid. The water molecule donates a proton to ammonia, resulting in the formation of the ammonium ion (NH4+) and the hydroxide ion (OH-).
This reaction exemplifies the concept of proton transfer between species in a chemical reaction. According to the Bronsted-Lowry theory, the ammonia molecule (NH3) accepts a proton, making it a base. Meanwhile, water (H2O) donates a proton, making it an acid.
The Arrhenius acid-base theory defines an acid as a substance that releases hydrogen ions (H+) in an aqueous solution, and a base as a substance that releases hydroxide ions (OH-) in an aqueous solution. In the given equation, NH3 does not release H+ ions, so it does not fit the definition of an Arrhenius acid. Similarly, the hydroxide ion (OH-) in the product side does not fit the definition of an Arrhenius base.
Therefore, the most appropriate definition for NH3 in the given equation is Bronsted-Lowry base, as it accepts a proton from water to form NH4+ and OH-.

the light reactions produce atp and nadph h and this process also results in the release of
Answers
The light reactions produce ATP and NADPH, and this process also results in the release of oxygen.
Here's a step-by-step explanation of how this occurs:
1. Light reactions occur in the thylakoid membranes of chloroplasts in photosynthetic organisms.
2. When light photons are absorbed by pigments like chlorophyll, they excite electrons to a higher energy state.
3. These high-energy electrons are transferred through a series of proteins called the electron transport chain (ETC).
4. As electrons move through the ETC, they release energy, which is used to pump protons (H+) across the thylakoid membrane, creating a proton gradient.
5. This proton gradient drives the enzyme ATP synthase to produce ATP from ADP and inorganic phosphate (Pi).
6. Meanwhile, the electrons are ultimately passed to NADP+ (nicotinamide adenine dinucleotide phosphate) along with a proton (H+), reducing it to NADPH.
7. The loss of electrons from chlorophyll is replenished by splitting water molecules, a process called photolysis. This results in the release of oxygen gas (O2) as a byproduct.
In summary, the light reactions produce ATP and NADPH, and the process results in the release of oxygen.

Answers
The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of that substance by 1 degree Celsius. In this case, we have a ceramic sample with a mass of 75.0 grams and an input of 250.0 J of energy that causes a temperature increase of 4.66 °C.
To calculate the specific heat, we can use the formula:
q = m * c * ΔT
where q is the amount of heat energy, m is the mass of the substance, c is the specific heat, and ΔT is the change in temperature.
We know that q = 250.0 J, m = 75.0 g, and ΔT = 4.66 °C. So we can rearrange the formula to solve for c:
c = q / (m * ΔT)
Plugging in the values, we get:
c = 250.0 J / (75.0 g * 4.66 °C)
c = 0.840 J/g°C
Therefore, the specific heat of the ceramic sample is 0.840 J/g°C. Option (a) is the correct answer.
