How many moles of magnesium oxide are formed when 4 moles of magnesium react with oxygen
Four (4) moles of magnesium oxide are formed when 4 moles of
magnesium react with oxygen.
How many moles of sodium oxide will be produced when 10 moles of sodium react with oxygen
If 2 moles of sodium carbonate are used in the reaction how many grams of sodium chloride will be formed
Temperature is used to increase the volume of gas
, the answer is Charles' Law!
The correct value for the universal gas constant is
Values of general gas constant are: (value dependant on
units)
R = 0.08205746 [atm. ℓ.mol-1.K-1]
R = 8.314472 [Pa.m3.mol-1.K-1 or J.mol-1.K-1]
R = 1.99 [Cal.mol-1.K-1]
An increase in gas pressure is a result of an increase in molecular collisions
Sodium will react with oxygen to form sodium oxide Use the formula below to determine how many grams of sodium oxide will be formed if 46 grams of sodium are used in the reaction
