Question 5 is the second one.
Answer:
I thinks its B
Explanation:
Because im pretty sure mechanical waves travel through a medium which is matter.(But im really sorry if its wrong)
The volume of ammonia gas is 4096 mL.
Explanation:
As per the kinetic theory of gases, the volume occupied by gas molecules will be directly proportional to the temperature and number of moles of the gas molecules. Similarly, the volume occupied by gas molecules will be inversely proportional to pressure.
PV = nRT
So, V = nRT/P
As R = 0.082 L atm mol⁻¹ K⁻¹ , T = 273 K and P = 1 atm with n = 0.183 mol
Then,
V=(0.183*0.082*273)/1
V = 4.096 L = 4096 mL.
Thus, the volume of ammonia gas is 4096 mL.
Answer:
yes it did.
Explanation:
the product must have produced a smell therefore it created a gas. this means it was a chemical reaction
