Answer: [tex]CO_2(s)\rightarrow CO_2(g)[/tex]
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and
is negative when randomness decreases.
a)
2 molesof gas are converting to 2 moles of another gas , thus
is zero.
b)
1 mole of solid is converting to 1 mole of liquid, the randomness increases and thus
is positive.
b)
2 moles of ions are converting to 1 mole of solid, the randomness decreases and thus
is negative
d)
1 mole of solid is converting to 1 mole of gas, the randomness increases drastically and thus
is highly positive.
Isotopes= a group of atoms with the same no. of protons , but different no. of neutrons
Hydrogen isotopes

The name of the second isotope is deuterium and the name of the third isotope is tritium(radioactive).The most abundant isotope is
Lithium fluoride is a solid at room temperature because it is a salt that is held together by ionic bonds. Lithium. fluoride has a giant ionic structure.
c is the answer i odnt know the rest im only a sophmore
C + O2= CO2



CO2 is limit
5.4-3.72= 1.68 g of C is excess
5.4 g = 100%
3.72 g = x
x=68.9 %
