The answer to this question is A
Write an balance the equation
Na2O + H2O -> 2 NaOH
Calculate the molecular mass of Na2O and NaOH from the atomic mass from the periodic table.
Na = 23
O=16
H=1
Na2O = 23 * 2 + 16 = 62
NaOH = 23+16+1= 40
For the stoichiometry of the reaction one mole of Na2O = 62g produce two mol of NaOH = 2* 40= 80 g
120 g Na2O x 80g NaOH / 62g Na2O=
154.8 g NaOH
Question 17: answer:The solute is the drink crystals and the solvent is the water…
I wish I am correct
One is closer to the equator so be must be warmer
Answer:
the answer is D. stress
If a stress is applied, the equilibrium shifts to relieve this change in conditions.
