Answer: There are 576.46 number of grams present in 16.95 mol hydrogen peroxide 
.
Explanation:
Number of moles is defined as the mass of substance divided by its molar mass.
The molar mass of 
is 34.01 g/mol. Hence, mass of hydrogen peroxide present in 16.95 moles is calculated as follows.
Thus, we can conclude that there are 576.46 number of grams present in 16.95 mol hydrogen peroxide .
Answer:
there is no picture so we can't tell why the containers are heavy
A net ionic equation which tends to show the ions that underwent a change in the reaction
<h3>What is a reaction equation?</h3>
The term reaction equation is the term that can be used to describe the instance where reactants combine together. If this occurs in solution we can say that the reaction is an aqueous phase reaction because the reactants wee all dissolved in solution.
It is possible for ionic substances in solution to react. When this occurs, it is possible for us to put down a net ionic equation which tends to show the ions that underwent a change in the reaction and the product of this reaction may be a liquid, a gas or a solid.
In this case, the complete molecular equation can be written as;
Ba(NO3)2(aq) + Na2SO4(aq) -----> BaSO4(s) + 2NaNO3(aq)
The complete ionic equation can be written as;
Ba^2+(aq) + 2NO3^-(aq) + 2Na^+(aq) + SO4^2-aq) -----> BaSO4(s) + 2NO3^-(aq) + 2Na^+(aq)
Net ionic equation is;
Ba^2+(aq) + + SO4^2-aq) -----> BaSO4(s)
