Answer:
The half life time of first order reaction is 1.3 sec
Explanation:
Given:
First order rate constant 
Initial concentration 
M
From the formula of first order half life time,
So half life time is given by,
sec
Therefore, the half life time of first order reaction is 1.3 sec.
Answer:
I think Sammy is right because I'm sure the compound contains ionic bonds
Answer:
Mass of Oxygen = 32 grams
Explanation:
Given:
Mass of water = 36 grams
Mass of Hydrogen = 4 grams
Find:
Mass of Oxygen
Computation:
Using Law of Conservation of mass
Mass of water = Mass of Hydrogen + Mass of Oxygen
36 grams = 4 grams + Mass of Oxygen
Mass of Oxygen = 32 grams
We could use solar power, wind power, geothermal power, hydroelectric power, or nuclear power. There are probably more but this is what I can think of off the top of my head. I hope this helps. Let me know if anything is unclear.
