what is the heat required to heat in 50 g sample of ice from -65 degrees Celsius to -40 degrees Celsius​

Nonpoint source pollution is difficult to control because it

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
