Answer:6M
Explanation:
From Co= 10pd/M
Where Co= molar concentration of raw acid
p= percentage by mass of raw acid=20%
d= density of acid=1.096g/cm3
M= molar mass of acid=36.5
Co= 10×20×1.096/36.5=6M
Answer:
The bond dissociation energy to break 4 bonds in 1 mol of CH is 1644 kJ
Explanation:
Since there are 4 C-H bonds in CH₄, the bond dissociation energy of 1 mol of CH₄ is 4 × bond dissociation energy of one C-H bond.
From the table one mole is C-H bond requires 411 kJ, that is 411 kJ/mol. Therefore, 4 C-H bonds would require 4 × 411 kJ = 1644 kJ
So, the bond dissociation energy to break 4 bonds in 1 mol of CH₄ is 1644 kJ
The answer is isotonic solution. These are solutions where
the solute concentration in the solution and inside the cells are levelled and consequently
water flows consistently. When red blood cells are positioned in an isotonic
solution the cells would always stay the same.
