One of the ways to minimize a collision is to slow down: When you can't find an escape and you're definitely going to collide with something, you should slow your vehicle down as much as possible.
Hope this helps ^^
Answer:
The gases will expand until a volume of Vf= 10812 cm^3
Explanation:
Since the gas mixture is expanding at constant pressure
and therefore
knowing that 1 torr=133,32 Pa
therefore
Moles of nitrogen = 49.84 / 28 = 1.78
Moles of hydrogen = 10.7 / 2 = 5.35
Molar ratio of nitrogen to hydrogen = 1 : 3
Hydrogen required = 1.78 x 3 = 5.34
Therefore, hydrogen is in excess and nitrogen is the limiting reagent.
The distance from the nucleus is close to the electron orbital of the earth
To predict the theoretical yield we would have to know the amount we of product we actually produced in a reaction, and the amount that should have been produced based on calculations involving the balanced equation for the reaction.
For instance, suppose we made water from hydrogen and oxygen. Starting with 2 moles of hydrogen and 1 mole of oxygen we should produce 2 moles of water (or 36 gram). But suppose we actually ran the reaction in the lab and collected only 34g of water.
The percent yield would be 34g / 36g x 100 =94.4%
So, if I'm reading your question correctly, 20g is the experimental yield and 10% is the percent yield.
Plugging in gives us 10/100 = 20/x
The theoretical yield must be 200g.

I HOPE THAT HELP MY FRIEND :)
