Answer:
The two factors that increase the size of a population are natality, which is the number of individuals that are added to the population over a period of time due to reproduction, and immigration, which is the migration of an individual into a place.
PH is the scale of measurement to check either the solution is acidic or basic. if the pH value is greater than 7, the solution is towards basicity and if the pH value is less than 7, the solution is towards acidity.
pKa is the dissociation constant and it is used to describe the change in pH value, when pKa is equal to pH: 50% of the ionizable group is protonated and 50% of the enzymes will be active.
So 50% of the enzymes will be active.
Answer:
Mass = 2.65 g
Explanation:
Given data:
Mass of sodium carbonate = ?
Mass of water = 0.125 g
Molality = 0.200 m
Solution:
Formula:
Molality = number of moles of solute / mass of solvent in Kg
by putting values,
0.200 m = Number of moles of solute / 0.125 kg
Number of moles = 0.200 m × 0.125 kg
Number of moles = 0.025 mol
Mass of sodium carbonate:
Mass = number of moles × molar mass
Mass = 0.025 mol × 106 g/mol
Mass = 2.65 g
Answer:
it is usually a restaurant that is located all over a certain country.
The grams of silver formed by the passage of 9,604 c through an electrolytic cell that contains a molten silver salt is 10.7g.
Acc. Faraday’s law of electrolysis,
W=(I×t×M) /nF
W=Faraday’s constant=96500
F=time M=molar mass
N=no. Of el.
It=9604C
Given,
Molar mass of silver=108g/mol.
n=1.
Then weight of silver deposited can be given as
W=(9604×108)/(96500×1)
= 10.7g
Thus we concluded that the silver deposited is 10.7g
