Answer:
C = 0.08M
Explanation:
molar mass of AlCl3
Al =27
Cl = 35.5
27+3(35.5) =133.5g/mol
n= mass/Molar mass
n =CV
CV = mass/molar mass
C x 500 x 10^-³ = 5/133.5
C x 500 x 10^-³ = 0.04
C = 0.04/500 x 10^-³
C = 0.08M
Answer: -
sigma factor mRNA RpoH sigma H sigma 32
Explanation: -
It is the heat shock sigma factor which activates due to heat. The factor will bind with to the polymerase-core-enzyme. After this other heat ans shock proteins are expressed.
This thus enable the cell to survive higher temperatures. Some of the enzymes that are expressed upon activation are chaperones, proteases and DNA-repair enzymes
Answer:
The correct answers are C and D.
Answer:
Explanation:
The mass percentages of chlorine and fluorine:
Given:
Mass of chlorine = 5.753g
Mass of fluorine = 9.248g
Find the total of the masses given:
Total mass = mass of chlorine + mass of fluorine = 5.753 + 9.248 = 15.001g
% of Cl = 
x 100
% of Cl = 
x 100 = 38.35%
% of F = 
x 100
% of F = 
x 100 = 61.65%
C. Weak acids partially ionize
