While balancing equation write the physical state of reactants and products as well as any reaction conditions.
What is reactants ?Reactants are the substances that are present at the start of a chemical reaction. They are typically the substances that are used up during the reaction and are converted into different products. Reactants are usually written on the left side of a chemical equation, while the products are written on the right side. Reactants are essential components of any chemical reaction and are essential in order for the reaction to take place. Reactants are also known as substrates or starting materials.
Balancing the Following Equations:
1) CuSO4(s) + 2KI(aq) → Cu2I2(s) + K2SO4(aq) + I2(g)

Negative ions, designated by the notation (OH ), are always present in any acid or base. The concentration. [OH"] of these ions is related to H by the equation OH H = 10-14 moles per liter.
Find the concentrations of OH and Hl in moles per liter for the substances with the following pH value pH = 7.8
The pH of a solution is given by the expression:\(pH = -log[H+],\)
where [H+] is the hydrogen ion concentration in mol/L.
To find the concentration of [H], we use the equation:
pH = -log[H+]7.8
= -log[H+]H+
= 10^-7.8H+
= 1.58 x 10^-8 moles per liter
Now, let's find the concentration of [OH-] by using the formula:
OH- H+ = 10^-14[H+]
= 1.58 x 10^-8OH- (1.58 x 10^-8)
= 10^-14OH-
= (10^-14) + (1.58 x 10^-8)OH-
= 1.0000000000000158 x 10^-14 moles per liter
OH- = 1.00 x 10^-14 moles per liter (rounded to two decimal places)
Concentration of [H] is 1.58 × 10⁻⁸ moles per liter and the concentration of [OH] is 1.00 × 10⁻¹⁴ moles per liter.

How many moles of water are produced from the reaction of oxygen with four moles of propane (C3H8)? C3H8 + 5O2 --> 3CO2 + 4H2O
Answers
Answer:
Explanation:
The reaction is:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
We see, that the equation is ballanced.
As we have data from only one reactant, we assume the other is in excess.
Ratio is 1:4 (stoichiometry). We solve this, by a rule of three:
1 mol of propane can produce 4 moles of water
Then, 4 moles of propane, may produce
( 4 . 4 ) /1 = 16 moles of water can be made.
Remember, we always have to work with the limiting reactant.
The electrophilic aromatic substitution of isopropylbenzene with FeBr3, Br2 gives 1-bromo-4-isopropylbenzene. Complete the curved-arrow mechanism below, beginning with formation of the active brominating reagent. Remember to include lone pairs and formal charges where appropriate.
Answers
Answer:
See explanation below
Explanation:
When the bromine (Br₂) reacts in presence of FeBr₃ with the isopropylbenzene, the isopropylbenzene is a ring activator, therefore, it will promote the substitution in the ortho and para positions. However, as the Isopropyl is voluminic, the ortho position would have steric hindrance and hence, this product is not formed in greater proportions. Instead, the para position becomes more available to reaction, and this product is formed in majority.

A sample of certain gas have Volume of 1.25 L ATM _125 degree Celsius and5.0 ATM the gas is compressed 50.0 ATM a volume of 325 mL. what is final temperature?
Answers
The final temperature of the gas is approximately 40.96 Kelvin.
To determine the final temperature of the gas, we can use the ideal gas law, which states:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature in Kelvin.
First, let's convert the given temperatures to Kelvin. We have:
Initial temperature: -125 degrees Celsius = 148 K (approximate)
Final temperature: Unknown
The initial conditions of the gas are as follows:
Initial pressure (P1) = 1.25 atm
Initial volume (V1) = 1250 mL = 1.25 L (since 1 L = 1000 mL)
Initial temperature (T1) = 148 K
The final conditions of the gas are as follows:
Final pressure (P2) = 50.0 atm
Final volume (V2) = 325 mL = 0.325 L
Final temperature (T2) = Unknown
Using the ideal gas law, we can set up the following equation:
(P1 * V1) / T1 = (P2 * V2) / T2
Substituting the known values:
(1.25 atm * 1.25 L) / 148 K = (50.0 atm * 0.325 L) / T2
Simplifying the equation:
T2 = (50.0 atm * 0.325 L * 148 K) / (1.25 atm * 1.25 L)
T2 = 40.96 K

Hormones secreted into the hypophyseal portal system are delivered directly to the ________.
A. neurohypophysis
B. adenohypophysis
C. median eminence
D. infundibulum
Answers
Hormones secreted into the hypophyseal portal system are delivered directly to the adenohypophysis. The correct option is B.
The adenohypophysis, also known as the anterior pituitary gland, is a glandular tissue that secretes various hormones that regulate important physiological processes such as growth, reproduction, and metabolism. The hypophyseal portal system is a specialized network of blood vessels that connects the hypothalamus to the adenohypophysis, allowing the hypothalamus to regulate the secretion of hormones by the adenohypophysis.
When the hypothalamus releases a hormone into the hypophyseal portal system, it travels directly to the adenohypophysis where it stimulates or inhibits the release of a specific hormone. For example, the hypothalamus secretes gonadotropin-releasing hormone (GnRH) into the hypophyseal portal system, which stimulates the adenohypophysis to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for reproductive function.
In summary, the hypophyseal portal system plays a crucial role in regulating the secretion of hormones by the adenohypophysis. Hormones secreted into the hypophyseal portal system are delivered directly to the adenohypophysis, where they stimulate or inhibit the release of specific hormones that regulate various physiological processes in the body.
Thus, the correct option is B.

The statements which describe a typical titration curve for the titration of a strong acid by a strong base are The beginning pH is low, at the equivalence point, pH changes by a large value, and beyond the equivalence point, pH rises rapidly. The correct answer is C) I), III), and IV).
A typical titration curve for the titration of a strong acid by a strong base has the following characteristics:
I) The beginning pH is low (pH < 7) due to the presence of a strong acid.
II) The pH change is rapid in the beginning, as small additions of base cause a large increase in pH.
III) At the equivalence point, the pH is 7 (neutral) since the number of moles of acid is equal to the number of moles of base.
IV) Beyond the equivalence point, the excess base starts to dominate the solution, leading to a rapid rise in pH.
V) The equivalence point would be at a pH of 7 (neutral).
Therefore, statements I), III), and IV) are correct, and statements II) and V) are incorrect.

Suppose you have 100.00mL of a solution of a dye and transfer 2.00mL of the solution to a 100.00 -mL volumetric flask. After adding water to the 100.00mL mark, you take 5.00mL of that solution and again dilute to 100.00 mL. If you find the dye concentration in the final diluted sample is 0.000158M, what was the dye concentration in the original solution?
Answers
The dye concentration in the original solution can be calculated using the following equation:
C1V1 = C2V2
Where:
C1 = Initial dye concentration V1 = Initial volume (100.00 mL) C2 = Final dye concentration (0.000158 M) V2 = Final volume (100.00 mL)
Therefore, C1 = 0.000158 x 100.00/2.00 = 0.0079 M.
So, the dye concentration in the original solution was 0.0079 M.
It is important to note that when diluting a solution, the number of moles of solute (the substance being dissolved) remains constant. This means that the amount of solute in the initial solution is equal to the amount of solute in the final diluted solution, which is why the equation works in the way it does.
