Water(h2o) is composed of the same elements as carbon monoxide (co). how do their properties compare?
a. they have the same properties because they have the same arrangement of atoms.
b. they have different properties because the arrangement of atoms is different.
c. they have the same properties because they have the same atoms.
d. they have different properties because they have different atoms.

answer is b.

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.
