An udentified substance, y, was thought to be one of the following three compounds.

compound: a
melting point: 132 °c

compound: b
melting point: 133 °c

compound: c
melting point: 134 °c

y was mixed with each of the above compounds and the melting point of each mixture was determined. the following results were obtained.

mixture: y + a
melting point: 114 – 129 °c

mixture: y + b
melting point: 132 – 133 °c

mixture: y + c
melting point: 86 – 99 °c

deduce the identity of y. briefly explain your answer.

How many moles of oxygen gas are produced from the decomposition of six moles of potassium chlorate

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.
