Vascular plants are successful due to better transportation for water, nutrients and reproduction.

Explanation:

I got it right at school and hope this helps you learn to STUDY.jk

According to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:

Plants with seeds, including flowering plants and conifers, produce pollen grains as a component of their reproductive process. They are often carried by wind or pollinators, such as bees, to the female reproductive organs of the same or different plant species, where they can fertilize female gametes (egg cells) and begin the development of seeds.

They carry the male gametes (sperm cells) of the plant. Many plant species depend on pollen grains for successful reproduction, and these grains have evolved a variety of forms, sizes, and surface features that make them easier to disperse and be recognized by pollinators.

Therefore, according to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:

A. Oxidation-reduction

Explanation:

I assume you mean the reaction is:

Ag2NO3(aq) + Cu(s) -> 2Ag(s) + Cu(NO3)2(aq)

Either way:

Solids have the oxidation number of 0. So in the beginning of the reaction Cu(s) has the oxidation number 0, and at the end it has a oxidation number of +2. So it was oxidized.

Ag in the beginning of the reaction has the oxidation number of +1, and ends with the oxidation number of 0. It was reduced.

So its an oxidation reduction.

Explanation:

Answer:

3.) 195

Explanation:

Because platinum is 195.079 amu (its on the periodic table)

A purple box has P t at the center and 78 above. Below it says platinum and below that 195.08. Rounded to the nearest whole number, 195 is the atomic mass of platinum. Therefore, option C is correct.

The number of protons an element contains determines its atomic number, which is used to distinguish one element from another. The total number of protons and neutrons in an element determines its mass number.

The mass number is the total number of protons and neutrons in the nucleus. This is due to the fact that each proton and neutron has a mass of one atomic mass unit (amu). You can determine the mass of the atom by multiplying the total number of protons and neutrons by 1 amu.

Because its numerical value is equal to the element's molar mass, the average atomic mass is helpful. In turn, this helps determine how much of a solid.

The atomic mass of platinum is 195. Because atomic mass is always the bottom number below the name of the element.

Thus, option C is correct.

The percentage yield of the reaction is

81 %

The percentage yield of a reaction will essentially tell you one thing: how effective the reaction is

Theoretical production is what we calculate in this context, assuming that absolutely every molecule of the reactants will actually react to form the desired product. The more efficient a reaction is, the closer it will be to theoretical production.

Thus, a reaction's theoretical yield will match a yield of 100%. The % yield of the reaction will match the actual yield, which is what you obtain in practise.

So, starting with the mass of calcium carbonate, CaCO3, the issue asks you to determine how effectively this reaction produces calcium oxide, CaO, and CO2.

As a result, it follows that 100.09 g of calcium carbonate should yield 56.08 g of calcium oxide if one mole of calcium carbonate should yield one mole of calcium oxide. Thus, 6 g of calcium carbonate should result in

60 g CaCO3 x 56.08 g calcium oxide/100.09 g calcium carbonate

3.36 g CaO

You know that your reaction actually produced 2.73 g of calcium oxide. This means that its percent yield was

2.73 g CaO x 100% yield/3.36 g CaO =

81 %

Hence, percentage yield of a reaction is 81 %

When the air molecules inside the tire cooled down, they moved slower, exerting less pressure on the inside walls of the tires. This is why Amy observed a lower reading of 29 PSI during the night compared to the normal reading of 35 PSI on a hot day.

The correct statement that explains what Amy observed is:

d. The air molecules cooled inside the tire causing them to move slower, exerting less pressure on the inside walls of the tires in the evening.

This observation can be explained by the ideal gas law and the relationship between temperature and pressure. According to the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin.

When the temperature decreases, as it did during the night, the kinetic energy of the air molecules decreases. As a result, the molecules move slower, leading to fewer collisions with the walls of the tire. Since pressure is caused by the force exerted by gas molecules colliding with the walls of the container, the decrease in molecular motion leads to a decrease in pressure.

The malate dehydrogenase reaction is a part of the citric acid cycle. Given the concentrations provided ([malate] = 1.31 mM, [oxaloacetate] = 0.290 mM, [NAD+] = 170 mM, [NADH] = 68 mM) and the standard free energy change (ΔG°' = 29.7 kJ/mol), we can calculate the free energy change (ΔG) for this reaction at 37°C (310 K) using the equation:
ΔG = ΔG°' + RT ln ([oxaloacetate][NADH])/([malate][NAD+])
Where R is the gas constant (8.314 J/mol·K) and T is the temperature (310 K). Plugging in the given values, we can find the free energy change for this reaction at the specified conditions. Therefore, the free energy change for the malate dehydrogenase reaction at pH 7 and 37.0°C, with the given concentrations, is 57.6 kJ/mol.

The malate dehydrogenase reaction is a crucial step in the citric acid cycle, converting malate and NAD+ to oxaloacetate and NADH. To calculate the free energy change for this reaction, we can use the equation:
ΔG°' = -RTln(Keq)
Where R is the gas constant (8.314 J/mol*K), T is the temperature in Kelvin (310 K), and Keq is the equilibrium constant for the reaction.
To calculate Keq, we need to use the concentrations given in the problem:
Keq = ([oxaloacetate] * [NADH])/([malate] * [NAD+])
Plugging in the given concentrations, we get:
Keq = (0.290 * 68)/(1.31 * 170) = 0.00588
Now we can calculate ΔG°' using the first equation:
ΔG°' = -RTln(Keq) = - (8.314 J/mol*K) * (310 K) * ln(0.00588) = 44.2 kJ/mol
However, the given value for ΔG°' is 29.7 kJ/mol. To calculate the actual free energy change for the reaction at the given concentrations, we can use the equation:
ΔG = ΔG°' + RTln(Q)
Where Q is the reaction quotient, which is calculated using the same equation as Keq, but with the actual concentrations instead of the equilibrium concentrations.
Plugging in the given concentrations, we get:
Q = (0.290 * 68)/(1.31 * 170) = 0.00588
Now we can calculate ΔG:
ΔG = 29.7 kJ/mol + (8.314 J/mol*K) * (310 K) * ln(0.00588) = 57.6 kJ/mol
Therefore, the free energy change for the malate dehydrogenase reaction at pH 7 and 37.0°C, with the given concentrations, is 57.6 kJ/mol.

The base name for an ester with a propyl group attached to the carbonyl carbon atom is "propyl ester." In the context of a simulation, you would need to extend the left chain according to the given parameters within the simulation for the specific compound you are working with.

If we extend the left chain of an ester with a propyl group attached to the carbonyl carbon atom as far as the simulation allows, we would have the following structure:

CH3-(CH2)2-C(=O)-OR

Where R represents the rest of the ester molecule.The base name for an ester with a propyl group attached to the carbonyl carbon atom is propyl propanoate. This name is derived from the parent carboxylic acid, which is propanoic acid (also known as propionic acid), and the alcohol used to form the ester, which is propanol (also known as 1-propanol or n-propanol).The esterification reaction between propanoic acid and propanol yields propyl propanoate as the ester product, with the elimination of a molecule of water.

Explanation:

Molarity = number of moles / volume

If 550 mL of a 3.50 M KCl solution are set aside and allowed to evaporate until the volume of the solution is 275 mL, which is half of 550 mL, the molarity of the solution with the same number of moles of KCl is 3.5 * 2 = 7.00 M

The molarity of the solution will be 7 M.

The total count of moles of solute per liter of a particular solution is known as a solution's molarity.

The volume of just an object is a measurement of how much space it takes up.

Molarity of the solution can be determined by the formula:

\(M_{1} V_{1} = M_{2} V_{2}\)

where, M = molarity of solution. V = volume.

Given data:

\(M_{1}\) = 3.50 M

\(M_{2}\) = ?

\(V_{1}\) = 550 mL

\(V_{2}\) = 275 mL

Now, put the value of given data in molarity equation.

\(V_{2} = M_{1} V_{1} /M_{2}\\V_{2} = (3.50 M) (550 mL) / (275 mL)\\V_{2} = 7 M\)
