Nata [24]

The first step Niven has to do in his calculation is to Balanced the chemical equation. The answer is letter A. The key in the balancing of chemical reaction is to make sure that you got the exact chemical formula of the substance that is reacting and the yielded product. After getting the formula, identify first the hardest element/atom to be balanced such as Na, Zn, Cl, etc. Then proceed to the easier ones such as O, H. Make sure to not the atoms present in the molecule of the substance.

Radda [10]

A variable, which is controlled or changed in a scientific experiment to examine the influences on the dependent variable is known as an independent variable. On the other hand, a dependent variable refers to the variable, which is being measured and tested in a scientific experiment.  

In the given case, one is observing that how the amount of salt in a mouse food influences the water the mouse drinks. Thus, the amount of salt in the food in the given case is an independent variable, as one can determine the amount of water consumed by the mouse, by manipulating the amount of salt intake given to the mouse.  

Hence, the correct answer is option B.
