Answer:
2KClO3--------->2KCl + 3O2
A.2SO₂ + O₂ + 2H₂O → 2H₂SO₄
B.Moles of SO₂ = 67.2 / 22.4Moles of SO₂ = 3 molesMoles of H₂SO₄ = 3 molesMass of H₂SO₄ = 3 x 98Mass of H₂SO₄ = 294 grams
Assuming sulfuric acid to have the same density as water,density = 1000 g / LVolume = mass / densityVolume = 294 / 1000Volume = 0.29 liters of sulfuric acid
Answer:
c
Explanation:
because when you hold a solid in your hand does it move does it shift no it stays the same so it doesn't take the form of the container it's in cuz that's a liquid.
For an exothermic reaction,heat energy is released out.
Enthalpy change = Energy of products - Energy of reactants
Here enthalpy change is negative,as energy of products is less than energy of reactants.
Hence heat is released in exothermic reactions.
And the products have lower potential energy than the reactants, and the enthalpy change is negative.
