Answer:
171.34 g/mol
Explanation:
Ba molar mass = 137.328 g/mol
O molar mass = 15.999 g/mol * 2 = 31.9980 g/mol
H molar mass = 1.008 g/mol * 2 = 2.0160 g/mol
137.328 + 31.9980 + 2.0160 = 171.3420 = 171.34 g/mol

Explanation:
Mol is the amount of molecules in something. Mol are similar to donuts, if you have a dozen of something you have 12 of them. If you have a mol of Hydrogen gas you 6.02•10^23 molecules of Hydrogen gas. If you are taking a chemistry class you will probably receive questions involving converting grams to mol and vice versa.
Converting Grams to Mol:
grams of x•(1/molecular mass of x)
note: you can find molecular mass of x by looking at the masses of the elements you need to add up in the periodic table
Converting Mol to Grams:
mol of x•(molecular mass of x)
The result of an exothermic reaction is released heat. According the Le Chatelier's principle, increasing<span> the </span>temperature means increasing<span> the amount of products. This means that </span><span> there will be more reactants left at equilibrium.</span>

Answer:
Explanation:
The kinetic molecular theory of gases depicts the characteristics and behavior of the gases in function of its particles (atoms or molecules).
As stated per the kinetic theory, a gas is consituted by a large amount of tiny particles in rapid random motion.
As result of this rapid continous motion, a huge number of particles are colliding at any moment against the walls of the vessel that contains the gas. The <em>gas pressure</em>, then, is the result of the force that the particles of gas exert over the walls of the container.
As per definition, the net force of may particles divided by the area gives the pressure: P = F / A.
So, the pressure is the force per unit area, which permits you to complete the sentence:
<em>Gas pressure results from the force exerted by a gas per </em><em><u>unit area.</u></em>
