Answer:
The answer is 6.941 but I dont really have the explanation
Explanation:
Answer:
both are physical properties
Explanation:
A is about it's malleability and B is about it's density. These are physical properties
<span>Radioactive waste, as its name implies, is a source of radiation that can be harmful to living organisms. Therefore it needs to be disposed of very carefully in such a way that the radiation cannot reach human beings and other living organisms. One method to do this is to bury the waste in deep pits. </span>
The chemical reaction is expressed as:
3Ba(NO3)2 + 2Na3PO4 = Ba3(PO4)2 + 6NaNO3
To determine the percent yield, we need to determine the theoretical yield of the reaction from the given amounts of the reactants. We do as follows:
0.3 mol 3Ba(NO3)2 ( 2 mol Na3PO4 / 3 mol Ba(NO3)2) = 0.2 mol Na3PO4
Therefore, the limiting reactant would be Ba(NO3)2 since it is consumed completely in the reaction.
Theoretical yield = 0.3 mol 3Ba(NO3)2 ( 1 mol Ba3(PO4)2 / 3 mol Ba(NO3)2) = 0.1 mol Ba3(PO4)2
Percent yield = actual yield / theoretical yield = 0.095 mol Ba3(PO4)2 / 0.1 mol Ba3(PO4)2 x 100 = 95%
