Answer: what is the effect of ( pressure ) on the volume of a gas
If the pressure on a gas is increased, then it’s volume will ( decrease ) because the gas molecules will ( be pushed closer together)
Explanation:
Answer:
7 moles
Explanation:
Given data:
Moles of hydrogen = 7 mol
Moles of water formed = ?
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Now we will compare the moles of water with hydrogen from balance chemical equation:
H₂ : H₂O
2 : 2
7 : 7
So in the presence of excess oxygen and 7 moles of hydrogen seven number of moles of water produced.
Answer:
jet streams
Explanation:
THE JET STREAM Narrow bands of exceedingly high speed winds are known to exist in the higher levels of the atmosphere at altitudes ranging from 20,000 to 40,000 feet or more. They are known as jet streams.
Some examples of endothermic reactions include melting solid salts, cooking an egg, baking bread, water evaporations and melting ice cubes
