3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K
IDEAL GAS LAW:
- The temperature of a gas can be calculated using the ideal gas law equation:
PV = nRT
Where;
- P = pressure (atm)
- V = volume (L)
- n = number of moles (mol)
- R = gas law constant (0.0821 Latm/molK)
- T = temperature (K)
- According to this question, P = 1.5atm, V = 2.7L, n = 3.5moles, T = ?
- 1.5 × 2.7 = 3.5 × 0.0821 × T
- Therefore, 3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K

Answer:
50000 dollars or 5 e5
Explanation:
Mr. Garibay has 
dollars in his bank.
Scientific notation represents the data in the format of expanded number or with e character.
For instance, 5.0 * 10^4 dollars = 50000 dollars or 5 e5
A) acids because they start with h
Answer:
The right answer is:
Replacing the powdered lead oxide with its large crystals
Removing lead (IV) oxide from the reaction mixture
Using 1.0 gram of lead (IV) oxide
Explanation:
Based on the given information this reaction is the catalytic decomposition of H₂O₂ into water and oxygen using Lead (IV) oxide as a catalyst.
- The catalyst surface area is directly proportional to the reaction rate
- So, Replacing the powdered lead oxide with its large crystals would decrease the reaction rate due to the has larger surface area than its large crystals.
2. Also, Removing lead (IV) oxide from the reaction mixture the reaction rate decreased because as the catalyst is removed.
3. Using 50 cm³ of hydrogen peroxide doesn't affect the rate because the concentration of the reactant doesn't change.
4. Using 1.0 gram of lead (IV) oxide would decrease the reaction rate because the amount of catalyst decreased
So, The right answer is:
Replacing the powdered lead oxide with its large crystals
Removing lead (IV) oxide from the reaction mixture
Using 1.0 gram of lead (IV) oxide
