<h3>
Answer:</h3>
1270 Psi
<h3>
Explanation:</h3>
<u>We are given;</u>
- Pressure in the tank, P₁ as 422 psi
- Temperature in the tank, T₁ as 20.0 K
- New temperature in the tank, T₂ as 60.0 K
We are required to determine the pressure at 60.0 K
- We are going to use the pressure law;
- According to the pressure law, the pressure of a gas is directly proportional to the temperature at constant volume.
- That is;
- Thus,
- At different pressures and temperature;
- Thus, rearranging the formula;
Hence;
Therefore;
P₂=1266 Psi
= 1270 Psi
Thus, the pressure at 60.0 K is 1270 Psi
Data:
Explanation:
The rate constant as a function of the temperature can be expressed using the Arrhenius equation, as follows,
Then, find a value for the constant A, according to the data given in the exercise,
As the rate constant has units then, the reaction corresponds to one of first order. Then, the reaction corresponds to:
Which tell the amount of mass (mol) is produced by second per unity of volume.
Answer:
If the reaction goes twice fast, the reaction rate corresponds to,
The expression above can be reduced to:
Replacing k(T) in order to obtain the temperature T,
Replacing all values,
Answer:
d. N
Explanation:
Chemical equation:
Pb(NO₃)₂(aq) + K₂SO₄(aq) → PbSO₄(s) + KNO₃(aq)
Balanced Chemical equation:
Pb(NO₃)₂(aq) + K₂SO₄(aq) → PbSO₄(s) + 2KNO₃(aq)
Ionic equation:
Pb²⁺(aq) + 2NO₃⁻(aq) + 2K⁺(aq) + SO₄²⁻(aq) → PbSO₄(s) + 2K⁺(aq) + 2NO₃⁻(aq)
Net ionic equation:
Pb²⁺(aq) + SO₄²⁻(aq) → PbSO₄(s)
The NO₃⁻(aq) and K⁺(aq)are spectator ions that's why these are not written in net ionic equation. The PbSO₄ can not be splitted into ions because it is present in solid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
well none its made from iron nut i would go with c. a solution sorry if im wrong tell me in comments
