The answer to this item depends entirely to the chemical reaction. If the compound, NH4Cl, is in the left hand side of the reaction, when it is added, the reaction will shift to the left. In the same manner, when the compound is in the right-hand side of the reaction, the reaction will shift to the right.
This happens because initially the reaction is in equilibrium and adding another compound to it will most likely lead to the shifting of the reaction.
Planets revolve around the sun because of gravity. When the planets were made, the sun's gravity was strong enough so that the planets continued to stay around the sun and orbit.

Answer:
Absolute error 
% Error 
5
Explanation:
The absolute error is the the difference in the measured value and the actual value of a quantity.
Here the actual value is 
grams
The measured value is 
grams
Absolute error
Percent error
Where AE stands for absolute error and AV stands for absolute value.
