Question 1 Consider the Relich-Kwong equation of state P = \frac{RT}{v-b} - \frac{a}{v(v+b)\sqrt{T}}P=v−bRT−v(v +b)Ta

For methane, a = 32.19a=32.19 bar(m^33/(kg\cdot⋅mol) )^22 K^{0.5}0.5 and b = 0.02969b=0.02969 m^33/(kg\cdot⋅mol) .

Find the specific volume at the critical point predicted by this equation in m^33/kmol.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
