According to the stoichiometry the CO2 formed is 1/2 the moles of H2O. So take the moles of CO2 as 5moles.
n=m/M
Where :
n = mole
m = mass
M = molar mass
Molar mass of CO2 = 44gmol^-1
Therefore mass = 5mol× 44gmol^-1= 220g
Metals have high density. They are always solids at room temperature.
Metalloids have intermediate density. They are generally solids at room temperature.
Non-metals have low density. They can be solids, liquids or gases at room temperature.
Based on this, the <span>class of elements that includes all of the elements that are gases at room temperature is the non-metals</span>
N is newtons so it would be false
