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
Answer:
How many atoms are in 6.5 moles of zinc? 6.5 moles. 6.02 x 10. 23 atoms = 3.9 x 10. 24 ... 55.8g. 1 mole. 6. What is the mass of 0.250 moles of aluminum?
Explanation:
hope this help rate me
The answer is D. Strong electrolytes
Strong electrolyte is a solute or solution that completely or almost completely dissociates when in solution. These are good conductors of electricity only when in molten/aqueous solution.
Strong electrolyte(aq) → Cation+(aq) + Anion−(aq)
Length=The distance between two points
Mass=The amount of matter contained in a body
Time=The interval or duration between two events
Temperature=The hotness and coldness of a body
I think it's false but don't be mad if it's not right
