Answer:
1086.2 L
Explanation:
The computation of the volume of the elevation is given below:
Here we assume the volume of the elevation be x
As we know that
V¹ ÷ T¹ = V² ÷ T²
Here
V^1 = 1500
T^1 = 290
V^2 = x
T^2 = 210
Now place these values to the above formula
So,
1500 ÷ 290 = x ÷ 210
x = 1086.2 L
The pH of 9.643 of 50 ml of 0.1000 M methylamine solution after the following volume of 0.1000 M HNO₃; where added 0
What is pH Value ?
A figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline.
- n(CH₃NH₂) = Cm x V = 0.1 x 0.05 = 0.005mol
- n(HNO₃) = CM x V = 0.1 x 0 = 0 mol
CH₃NH₂ + H₂O = CH₃NH₃⁺ + OH⁻
1mol CH₃NH₂ => 1 mol OH⁻
0.1 M => X = 0.1 M OH⁻
Methylamine, CH₃NH₂, is a weak base that reacts with water according to the above equation.
- For this reaction at equilibrium,
Kb = 4.4 x 10⁻⁴
Cm (OH⁻) = 0.1 x 4.4 x 10⁻⁴= 4.4 x10⁻⁵ M
pOH = -log [OH⁻] = - log (4.4 x 10⁻⁵) = 4.357
Using ;
pH + pOH = 14
we find the pH value:
pH = 14 - pOH = 14 - 4.357 = 9.643
In the similar way, It can be done for 25,3,50,55 and 60

Answer:
Ketones and ketoacids are alternative fuels for the body that are made when glucose is in short supply. They are made in the liver from the breakdown of fats. Ketones are formed when there is not enough sugar or glucose to supply the body's fuel needs. This occurs overnight, and during dieting or fasting.
Explanation:
Acid base reactions also known as neutralization reactions are reactions that occur between acids and bases thus the name. Anytime this happens the product will niether an acid or base it will be neutralized to a neutral pH as in that of pure water pH 7.
Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.
