We can get ΔG from this formula:
ΔG = -R*T*(㏑K)
when K = p(N2O4) / p(NO2)^2
we have P(N2O4) = 1.64 atm
and P(NO2)^2 = 0.38 atm
by substitution:
=1.64 atm / (0.38)^2
= 11.36
and R = 8.314
and T = 298 K
so by substitution on ΔG formula:
∴ ΔG = 8.314 *298 *(㏑ 11.36)
= - 6020.7
Answer:
Explanation:
1.). A pure substance has a/an ___definite____ composition.
Pure substances have a definite composition and all their parts are same throughout.
2.). A/An ___mixture____ is composed of two or more types of matter that can be present in varying amounts.
Mixture is a blend of two or more types of matter.
3.). A solution is a/an ___homogeneous ____ mixture.
Solutions are homogeneous mixtures of solutes and solvents.
4.). A mixture that is not uniform throughout is a/an ___heterogeneous ____ mixture.
A mixture that is not uniform throughout is said to be heterogeneous.
5.). A pure substance that cannot be broken down chemically is a/an _______.
An element : is a distinct substance that cannot be split-up into simpler substances.
6.). A characteristic of matter that’s not associated with a change in its chemical composition is known as a/an __physical_____ property.
Physical property tells us everything about what a substance is when no change is occuring to its constituents.
7.).Wax melting is an example of a/an ___physical change____ change in the state of matter.
Physical change is one that alters the physical properties of matter.
8.). A banana peel turning brown is an example of a/an ___chemical____ change in the state of matter.
Chemical change is one in which a new matter is formed.
<span>Hydrogen bonding between water molecules is the foundation of multiple properties of water such as cohesion, adhesion, surface tension, water's high specific heat, three states, and low freezing point which all contribute to water sustaining life. The three states of water coupled with the low freezing point allows organisms living in aquatic systems in cold climates to be protected from the freezing air temperatures by the layer of ice that forms across the surface of lakes and rivers. The high specific heat of water allows it to be a wonderful cooling agent for people, the water molecules can absorb large quantities of heat before evaporating of our skin when we sweat carrying the heat away as well. The cohesion and adhesion properties of water allow the tips of the tallest trees in the Amazon and Sequoia National Park to still receive water.</span>
