Answer:
1,15mL = V₂
Explanation:
Based on Charle's law the volume is directely proportional to the absolute temperature in a gas under constant pressure. The equation is:
V₁T₂ = V₂T₁
<em>Where V is volume and T absolute temperature of a gas where 1 is initial state and 2, final state.</em>
The V₁ is 1.23mL
T₁ = 32°C + 273.15 = 305.15K
T₂ = T₁ - 20°C = 285.15K
Replacing:
1.23mL*285.15K = V₂*305.15K
<h3>1,15mL = V₂</h3>

Oxygen is the 8th element in the periodic table. This means that oxygen has 8 protons<span> and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8) (o_O)

R=[x2][y] rate law of the reaction
check:
if we double x2, r(new) =[2*x2][y]=2*[x2]*[y]=2*r
if we triple y, r(new) =[x2][3y]=3*[x2]*[y]=3*r
z- no effect, so z is not included
Answer : (b) The rate law expression for the reaction is:
![\text{Rate}=k[SO_2]^2[O_2]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BSO_2%5D%5E2%5BO_2%5D)
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The general reaction is:
The general rate law expression for the reaction is:
![\text{Rate}=k[A]^a[B]^b](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BA%5D%5Ea%5BB%5D%5Eb)
where,
a = order with respect to A
b = order with respect to B
R = rate law
k = rate constant
![[A]](https://tex.z-dn.net/?f=%5BA%5D)
and ![[B]](https://tex.z-dn.net/?f=%5BB%5D)
= concentration of A and B reactant
Now we have to determine the rate law for the given reaction.
The balanced equations will be:
In this reaction, 
and 
are the reactants.
The rate law expression for the reaction is:
![\text{Rate}=k[SO_2]^2[O_2]^1](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BSO_2%5D%5E2%5BO_2%5D%5E1)
or,
When an atom donates electrons and other gains electrons, they form ions and the bond is called the ionic bond. When the atoms share electrons between them, they form a molecule, and the bond is called the covalent bond.
The atoms can share one, two or three pairs of electrons in the same bond. If one pair is shared it's called a single bond or a covalent simple; if two pairs are shared it's called a double bond or a covalent double, and if three pairs are shared it's called a triple bond or a covalent triple.
If this helps, please mark me as brainly, if not thats ok. im just here to help you get good grades. :D
