Answer:
No
Explanation:
You can not have a reaction that produces "no mass". This breaks the law of conservation of mass. When gasses are produced, they will have a specific amount of mass associated with them which means they will have a weight. They will have to be accounted for
Answer:
32.8g/mole
Explanation:
Given parameters:
Mass of sample of gas = 32.8g
Volume = 22.4L
Unknown:
Molecular weight = ?
Solution:
To solve this problem we must understand that at rtp;
1 mole of gas occupies a volume of 22.4L
Number of mole of the gas = 1 mole
Now;
Mass = number of moles x molecular weight
molecular weight = = = 32.8g/mole
Answer: The number of Ni2+ ions is 1.46 × 10^18 ions
The number of Ag+ ions is 2.92 × 10^18 ions

I think it's D cuz gasoline is technically a chemical so chemical energy. and the Engine which is working is mechanical or kinetic
so d. first from chemical to mechanical
hope i helped thnx
