Lunch of a patient has 3 oz skinless chicken, 3 oz of broccoli, 1 medium apple, and 1 cup of nonfat milk
Energy content of 3 oz skinless chicken is = 110 kcal
Energy content of 3 oz broccoli = 30 kcal
Energy content of 1 medium apple = 60 kcal
Energy content of 1 cup non-fat milk = 90 kcal
So the kilocalories of energy patient obtained from lunch
= 110 kcal+ 30 kcal + 60 kcal + 90 kcal = 290 kcal
Atoms according to the kinetic molecular theory, are described in a solid to simply be vibrating in fixed positions, and not moving rapidly in the container. Because of this, they take a fixed volume and have fixed shape.
I honestly have no clue on this one
The estimation of the acidic and the basic character of a solution is called and defined by the pH. The ![\rm [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D)
concentration of the solution will be 
<h3>What is the pH?</h3>
pH is a measurement of the free hydrogen and hydroxyl ions in the solution of the substance.
It can be calculated as:
![\rm pH = - \rm log[H^{+}]](https://tex.z-dn.net/?f=%5Crm%20pH%20%20%3D%20-%20%5Crm%20log%5BH%5E%7B%2B%7D%5D)
Given,
pH = 3.75
Substituting values in the equation:
![\begin{aligned}\rm 3.75 &= -\rm log[H^{+}]\\\\\rm [H^{+}] &= 10^{-3.75}\\\\&= 1.7782 \times 10^{-4}\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Crm%203.75%20%26%3D%20-%5Crm%20log%5BH%5E%7B%2B%7D%5D%5C%5C%5C%5C%5Crm%20%5BH%5E%7B%2B%7D%5D%20%26%3D%2010%5E%7B-3.75%7D%5C%5C%5C%5C%26%3D%201.7782%20%5Ctimes%2010%5E%7B-4%7D%5Cend%7Baligned%7D)
Therefore, 
is the concentration of the hydrogen ions.
