D. Sometimes it is necessary to put forth new theories to explain experimental results,
Explanation:
Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.
Theories are explanation of scientific observations.
- Most scientists are critical and creative thinkers.
- They must be able to come up with a wide range of possible explanation to explain their findings.
- The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
- Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

Answer:
in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
Explanation:
Moles of phosphoric acid would be needed : 0.833
<h3>Further explanation</h3>
Given
15 grams of water
Required
moles of phosphoric acid
Solution
Reaction(decomposition) :
H3PO4 -> H2O + HPO3
mol water (H2O :
= mass : MW
= 15 g : 18 g/mol
= 0.833
From the equation, mol ratio H3PO4 = mol H2O = 1 : 1, so mol H3PO4 = 0.833

Answer:
b- The heat capacity ratio increases but output temperature don’t change
Explanation:
The heat capacity is the amount of energy required to raise the temperature of a body, by 1 degree. On the other hand, the specific heat capacity is the amount of heat required to raise the temperature of a of unit mass of a material by 1 degree.
Heat capacity is an extensive property meaning its value depends on the amount of material. Specific heat capacity is found by dividing heat capacity by the mass of the sample, thus making it independent of the amount (intensive property). So if the specific heat capacity increases and the mass of the sample remains the same, the heat capacity must increase too. Because of that options c and d that say that heat capacity reamins same are INCORRECT.
On the other hand, in which has to be with options a and b both say that the heat capacity increases which is correct, but about the output temperatures what happens is that if we increase the specific heat capacity of both fluids that are involved in a process of heat exchange in the same value, the value of the output temperatures do not change so only option a is CORRECT.
