Answer:- 1.90 atm
Solution:- It is based on combined gas law equation, PV = nRT
In this equation, P is pressure, V is volume, n is moles of gas, R is universal gas constant and T is kelvin temperature.
If we divide both sides by V then:
We know that, molarity is moles per liter. So, in the above equation we could replace 
by molarity, M of the gas. The equation becomes:
P = MRT
T = 20 + 273 = 293 K
M = 
Let's plug in the values in the equation:
P = 
P = 1.90 atm
So, the pressure of the gas is 1.90 atm.
Answer:
1 mol of water is produced in those conditions.
Explanation:
The reaction to produce water between H₂ and O₂ is this:
2H₂ + O₂ → 2H₂O
We don't have the amount of hydrogen, so we have to think that is in excess.
Let's work with oxygen.
Ratio is 1:2
For 0.5 mole of oxygen, I will make the double of moles of water.
Burning alcohol for fuel has been used throughout history. There are some alcohols that are the best ones to use as fuels because of their nature and can be synthesized chemicaly or biologicaly. Except, some of those alcohol also has a bad effect when burned for fuel as it would cause serious negative chemical effects when exposed to the human body such as blindness or death. Therefore, the best answer would be False.
Answer: C. Al (aluminum)
Explanation: it has 3 valence electrons :)
