Answer:
Newton believed that gravity was a force.
The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Newton was the first to have the idea that gravity is everywhere.
The empirical formula of Lorelai's compound is C₄H₁₀O
<h3>Data obtained from the question</h3>
- C = 64.8 g
- H = 13.62 g
- O = 21.58 g
- Empirical formula =?
<h3>How to determine the empirical formula</h3>
Divide by their molar mass
C = 64.8 / 12 = 5.4
H = 13.62 / 1 = 13.62
O = 21.58 / 16 = 1.35
Divide by the smallest
C = 5.4 / 1.35 = 4
H = 13.62 / 1.35 = 10
O = 1.35 / 1.35 = 1
Thus, the empirical formula of the compound is C₄H₁₀O

Answer: Option (b) is the correct answer.
Explanation:
Buffere is defined as the solution to whom when an acid or base is added then it resists any in change in pH of the solution.
This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. So, basically it keeps the concentration of both hydrogen ions and hydroxides equal. As a result, it helps in maintaining the pH of the solution.
And, the capacity of a buffer solution to resist the change is known as buffer capacity.
Thus, we can conclude that buffering capacity refers to the extent to which a buffer solution can counteract the effect of added acid or base.
Answer:
Potential energy
Explanation:
A mountain climber at the peak of a mountain has potential energy.
The potential energy of a body is stored energy in a body. It is function of mass and position of the body.
Mathematically;
P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Factor or condition in an experiment that changes as a result of the independent variable. constant: factors or conditions in an experiment that are kept the same in ao Trials of the experiment. Control: a set up without the variable being tested.
