Mass of reactants > mass of products
Answer:
Explanation:
2N₂O(g) → 2N₂(g) + O₂(g)
molecular weight of N₂O = 44
∆Hº = –166.7 kJ/mol
44 g of N₂O decomposes to give 166.7 kJ of heat
2.25 g of N₂O decomposes to give 166.7 x 2.25 / 44 kJ of heat
= 8.51 kJ of heat .
Answer:
The great confrontation between the two men occurred in 1686 when Newton published the first volume of his Principia and Hooke affirmed that it was he who had given him the notion that led him to the law of universal gravitation. Hooke demanded credit as the author of the idea but Newton denied it
Explanation:
H₂SO₄ represents Sulphuric acid or SO₄²⁻ ion when in aqueous as well as H⁺ and a little amount of HSO₄⁻ all of these ions can form in aqueous on dissolving H₂SO₄
