Explanation:
Mass of the organic compound = 200g
Mass of carbon = 83.884g
Mass of hydrogen = 10.486g
Mass of oxygen = 18.640g
The mass of nitrogen = mass of organic compound - (mass of carbon + mass of hydrogen + mass of oxygen)
Mass of nitrogen = 200 - (83.884 + 10.486 + 18.64) = 200 - 113.01
Mass of nitrogen = 86.99g
The empirical formula of a compound is its simplest formula.
It is derived as shown below;

<span>I think the correct answer is A. A
buffer is a substance that resists small change in the acidity of a solution
when an acid or base is added to the solution. Usually, a buffer involves a
weak acid or a weak alkali and one of its salt.</span>
Answer:
Yes
Explanation:
Because the higher radiation, people can get health problems and burns when exposed to high levels of heat.
B, more kinetic energy means more collisions and thus more reactions according to collision theory.
Chemical. burning is a chemical change
