Answer:
Matter always takes space (or has volume).
Answer: 1. 199.995 g of NaOH & 2. 2.014 g of H2
Explanation:
1. 5.00 mol H2O x __2 mol NaOH__ x __39.999 g__
2 mol H2O 1 mol
= 199.995 g of NaOH
2. 36 g H2O x __1 mol __ x __1 mol H2__ x __2.016 g__
18.016 g 2 mol H2O 1 mol H2
= 2.014 g of H2
Answer:
Mixture
Explanation:
It is made up of just one type of element (sulfer). Since multiple elements are joined together, it's an example of a mixture.
The balanced reaction equation for the combustion of butane is as follows;
C₄H₁₀ + 13/2O₂ ---> 4CO₂ + 5H₂O
the limiting reactant in this reaction is C₄H₁₀ This means that all the butane moles are consumed and amount of product formed depends on the amount of C₄H₁₀ used up.
stoichiometry of C₄H₁₀ to H₂O is 1:5
mass of butane used - 6.97 g
number of moles - 6.97 g / 58 g/mol = 0.12 mol
then the number of water moles produced - 0.12 mol x 5 = 0.6 mol
Therefore mass of water produced - 0.6 mol x 18 g/mol = 10.8 g
