Answer:
⇒ We have Na2O + H2O --> NaOH. We have 2 sodiums and 2 oxygens and 2 hydrogens on the left side, but only one of each on the right side.
Sodium Oxide + Water → Sodium Hydroxide
⇒ Na2O + H2O → 2NaOH .
Sodium oxide is used in ceramics and glasses. Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution.
<u>Answer:</u>
3.67 moles
<u>Step-by-step explanation:</u>
We need to find out the number of moles present in 350 grams of a compound.
Molar mass of = 24.305
Molar mass of = 35.453
So, one mole of = 24.305 + (35.453 * 2) = 95.211g
1 Mole in 1 molecule of =
Therefore, number of moles in 350 grams of compound = 0.0105 * 350
= 3.67 moles
