Answer:
Explanation:
Hello,
In this case, since we can consider hydrogen gas as an ideal gas, we check the volume-pressure-temperature-mole relationship by using the ideal gas equation:
Whereas we are asked to compute the moles given the temperature in Kelvins, thr pressure in atm and volume in L as shown below:
Best regards.
Answer: The balanced equation for overall reaction is:
(CH3)3AuPH3 ----> C2H6 + (CH3)AuPH3
Explanation:
The reaction mechanism is given as follows:
Step 1: (CH3)3AuPH3 ↔ (CH3)3Au + PH3 (fast)
Step 2: (CH3)3Au → C2H6 + (CH3)Au (slow)
Step 3: (CH3)Au + PH3 → (CH3)AuPH3 (fast)
To balance this equation, firstly, we conduct proper atom count for each steps of the reaction mechanism.
It is important to note that for a reaction that involves several steps, the rate law is normally derived from the slow step ( which is step2 from the above mechanism).
Therefore, the balanced chemical equation for the overall reaction is:
(CH3)3AuPH3 ----> C2H6 + (CH3)AuPH3
C. Condensation is the right answer
Answer:
C.Hydrogen
Explanation:
The hydrogen atom contains 1 proton and 1 electron, but no neutrons.
Answer:
They have the same mass
Explanation:
The two blocks have the same mass. Mass is the quantity of matter contained in a substance. Therefore, the two bodies have the same mass.
The weight is a measure of mass and gravity. The gravity on earth differs from that on the moon. Therefore, the two bodies have different weights.
Their volume is also different since one body is larger than the other. Therefore, density which is the mass per unit volume will also differ.
