Negative 2
Each electron contributes a minus one charge.
Answer: -
Mass of Hydrated KAl(SO₄)₂ = 2.0 g
Molar mass of anhydrous KAl(SO₄)₂ = 258.20 g/ mol
Mass of of anhydrous KAl(SO₄)₂ = mass of the 2nd heating = A
The mass of water released = mass of the Aluminum Cup + 2.0 grams of KAl(SO₄)₂ - mass of the 2nd heating
= H g
Moles of water released =
Moles of anhydrous KAl(SO₄)₂ =
Required ratio =
When landfills have a very poor maintenance, it would likely result in the release of harmful gases into the atmosphere. Among these poisonous gases released are carbon dioxide and methane in which if inhaled in an excessive amount, it could cause respiratory illnesses or it could be fatal.
