Answer:
How does the equilibrium change with the removal of hydrogen (H2) gas from this equation? 2H2S ⇌ 2H2(g) + S2(g) A. ... Equilibrium shifts left to produce less reactant.
Explanation:
option A is the correct answer
Equilibrium shifts right to produce more product.
I hope it will help you.
Aluminum to hydrogen gas ratio is 2 : 3 by looking at the coefficients of aluminum on the reactant side and hydrogen gas on the product side.
So from 2.0 mol of Al, 3.0 mol of H2 would form.
Answer:
The air pressure on a hot day is higher than on a cold day
Explanation:
In tire having constant volume, the air pressure on hot day is greater compared to that on a cold day.
From the combined gas law, at constant volume, it can be deduced that the pressure of a given mass of gas varies directly with the absolute temperature.
Mathematically;
=
So, it can be inferred that the higher the temperature of the tire, the more the pressure on the air inside and vice versa.
This idea has historical significance. The ancient Greek philosopher Democritus (born 460 BCE), who held that everything is composed of small particles moving in empty space, is credited with developing the first hypothesis we have about the microscopic universe. He had some concrete proof for this, such the fact that items like a new loaf of bread or a rose may give off a scent even when they are far from the source. Being a materialist, he thought that these odors originated from actual material particles released by the bread or the rose, rather than being purely a type of magic. He reasoned that these particles must float through the air, with some of them maybe landing in your nose where you can smell them immediately. This still makes sense in modern times. But many of us now have quite different perspectives on these "particles."
