The answer would be:
A. Cancel out CO because it appears as a reactant in one intermediate reaction and a product in the other intermediate reaction.
In this question, there are two half-reaction equations. To merge them up, you need to add the reactant with the reactant, then the product with the product. If there is a molecule on both side, you can cancel them. The full reaction would be:
C+ 1/2 O2 + CO + 1/2O2 ==>CO+ CO2 -----> remove CO from both side
C+ O2 ==>CO2
Answer:
enzymes because they lower activation energy.
Answer:
As potential energy increases, kinetic energy decreases
It's an inverse relationship
The given molarity of sodium hydroxide solution = 2.0 M
The required concentration of sodium hydroxide is 65 mL of 0.6 M NaOH
Converting 65 mL to L:
Calculating the moles of NaOH in the final solution:
Finding out the volume of 2.0 M solution taken to prepare the final solution:
Therefore, 19.5 mL of 2.0 M NaOH solution and make it up to 65 mL to prepare 0.6 M NaOH solution.
Answer:
256 K
Explanation:
Given data
- Ideal gas constant (R): 0.0821 atm.L/mol.K
We can determine the temperature of the gas using the ideal gas equation.
P × V = n × R × T
T = P × V / n × R
T = 4.20 atm × 20.0 L / 4.00 mol × 0.0821 atm.L/mol.K
T = 256 K
