Answer:
NaOH
Explanation:
Look at charge Na has +1 charge and Ca has +2 charge after dissociation . Greater charge Stronger lattice. And as we need weak Lattice, so NaoH is stronger base than Ca(OH)2.
Answer:
theory is diffrent from law
Explanation:
a Theory can never be proven to be true nd a law can usually be expressed
B. It keeps the warm inside
Molarity and normality are the ways of expressing concentration which includes the volume of the solution.
As we know,
Molarity is defined as the number of moles of solute dissolved in 1L of the solution. Thus,
M = no. of moles of solution/ Volume of solution on litres.
while, Normality is the number of gram equivalents of the solute dissolved per litre of the solution.
N = Gram equivalent of the solute/ volume of solution in litres.
while, the other concentration expressing terms such as mole fraction, molality includes the mass of the solution and solvent respectively.

Answer:
3.14 moles of hydrogen are produced
Explanation:
This is because for every 1 molesof hydrogen are produced 2 moles of oxygen are produced. So we take 6.28 divide it by 2 and we wend up with 3.14.
