Answer:
True
Explanation:
Here is an example: chemical properties include flammability, toxicity, acidity, reactivity. we observe the changes of these properties. Therefore, It's true.
I think the answer is that three electrons are gained, creating N-3
The reactants of photosynthesis are represented by 
and 
.
<h3>Photosynthesis</h3>
It is a reaction through which green plants make use of inorganic products such as water and carbon dioxide in the presence of solar radiation to make sugar. Oxygen is liberated as a by-product.
The equation of the reaction is represented by:
Thus, the reactants are represented by and respectively.

The answer is 1.03 quarts
<u>Answer:</u>
<em>One mole of a substance forms Instead of standard atmospheric pressure and temperature from its pure elements{ conditions being the same} then this change and enthalpy is known as </em><em>enthalpy of formation.</em>
<u>Explanation:</u>
The equation of this formation can let us know what actually happens
ΔH = ΔHf(products) - ΔHf (reactants)
Hence we can say this change in enthalpy formation is the difference between the sum of product and sum of reactants.
