What element/compounds are used in the melting of ice?

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.

In a covalent bond, two atoms are held together by the attraction between . the number of covalent bonds that an atom can form depends on the number of in the atom.

How do you calculate the mass of a product when the amounts of more than one reactant are given?
