Answer:
Showing respect
Explanation:
Being first at everything is immature, playing on a cell phone is being off task, and using a fire blanket to keep warm in class shows that you are doing nothing to contribute to the lab.
The volume of 15.7 M H2SO4 is required to prepare 12.0 L of 0.156 M sulfuric acid is 0.12 L
<h3>Data obtained from the question</h3>
From the question given above, the following data were obtained:
- Molarity of stock solution (M₁) = 15.7 M
- Volume of diluted solution (V₂) = 12 L
- Molarity of diluted solution (M₂) = 0.156 M
- Volume of stock solution needed (V₁) = ?
<h3>How to determine the volume of the stock solution needed</h3>
The volume of the stock solution needed can be obtained by using the dilution formula as shown below:
M₁V₁ = M₂V₂
15.7 × V₁ = 0.156 × 12
15.7 × V₁ = 1.872
Divide both side by 15.7
V₁ = 1.872 / 15.7
V₁ = 0.12 L
Thus, the volume of the stock solution needed to prepare the solution is 0.12 L

Answer : Its solubility at and 1730 torr is, 0.077 M
Solution :
As we know that the solubility of the gas is directly proportional to the pressure of the gas.
Or,
where,
= initial solubility of gas = 0.0342 M
= final solubility of gas = ?
= initial pressure of gas = 765 torr
= final pressure of gas = 1730 torr
Now put all the given values in the above formula, we get
Therefore, Its solubility at and 1730 torr is, 0.077 M
Scientific conclusions are based on evidence.
The type of chemical reaction is "Double displacement"
