A 4.5 mol sample of acetylene gas has a volume of 18 L at 25 Celsius.

Ineed this asap part i: scientific method what is the difference between science and pseudoscience? what is the scientific method?

How many grams of mgbr2 are needed to produce 75g or metal?

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.
