Answer: 19.4 g/cm3
Explanation: density is the relationship between mass over volume.
So density of gold is 15.7g/0.81cm3 = 19.4 g/cm3
Answer:vapor
Explanation: Because it is
Answer:
cause they like it that way
Explanation:
btw cant tell if this is legit or not
This is a redox reaction.
3Fe + 2O₂ → Fe₃O₄ (Fe⁺²O·Fe⁺³₂O₃)
Fe - 2e⁻ = Fe⁺²
Fe - 3e⁻ = Fe⁺³
O₂ + 4e⁻ = 2O⁻²
Answer:
46. 2 moles of NaOH
Explanation:
Balanced chemical equation between sodium hydroxide and sulfuric acid
2NaOH + H2SO4 = Na2SO4 + 2H2O
I mole of sulphuric acid is neutralized by = 2 moles of NaOH
23.1 mole of sulphuric acid is neutralized by = 2 x 23.1
= 46. 2 moles of NaOH
