CO2 is a compound, hope this is okay
Answer:
Liquids
Note: the attachment below shows the properly arranged chart
Explanation:
The order of molecular motion of matter from fastest to slowest is;
Plasma>Gases>Liquids>Solids
Liquids move faster than solids not slower.
You cannot find it if you do not know the information. Was there a molar mass given or do you know if it is asking for the molar mass?
Answer:
About 60 grams
Explanation:
The balanced equation of the reaction is given as;
2H2(g) + O2(g) → 2H2O(l)
From the equation;
2 mol of H2 reacts with 1 mol of O2
3 mol of H2 would require 3/2 mol of O2 (considering the 2:1 ratio)
The limiting reactant is H2 as it would be used up before H2. It determines the amount of product that would be formed.
2 mol of H2 produces 2 mol of H2O
3 mol of H2 would produce 3 mol of H2O (Considering the 1 : 1 ratio)
Converting moles to mass;
Mass = Molar mass * Number of moles
Mass = 18 * 3 = 54 g
The correct option is; About 60 grams
