Answer:
CaCO3+2HCl=CaCl2+H2O+CO2 this is the balanced reaction occur between calcium carbonate and HCl to minimize the hyperacidity.
Explanation:
CaCO3 reacts with hydrochloric acid produced by oxytonic cells of the stomach to generate calcium chloride (CaCl2) and water(H2O) along with the release of carbon dioxide(CO2) gas.
This reaction helps to minimize hyperacidity.
Answer:
(a)The molar mass of the gene fragment is 18220.071g/mol = 18.22 kg/mol
(b)The freezing point for the aqueous solution is C
Explanation:
The osmotic pressure (π) is given by the following equation:
= Concentration of solution
R = universal gas constant = 62.364
T = temperature
Weight of solute = w = 10.0 mg
Let the molecular weight of the solute be m g/mol.
Concentration =
m = 18220.071g/mol
Therefore, the molar mass of the gene fragment is 18220.071g/mol = 18.22 kg/mol
m is the molality of the solution.
m = mol/kg
= C
The freezing point for the aqueous solution is C
