Answer:
Explanation:
The relation between new scale and absolute temperature scale is given as follows
Aw = 2 K
for K = 273.15 ( freezing point of water at absolute scale )
Aw = 2 x 273.15 = 546.3 K
So each division of new scale is half the each division of absolute scale
each division of new scale is small .
The value of R = 8.314 J per mole per K
Here per K is equivalent to 2Aw
So the vale of R in new scale = 8.314/2 J per mole per Aw
= 4.157 J per mole per Aw
k = R / N
= 4.157 / 6.02 x 10²³
= .69 x 10⁻²³
= 6.9 x 10⁻²⁴ J per molecule per Aw .

Th first one is Iron and the second one is Xenon
A catalyst is a chemical substance that hastens the chemical reaction. This does not participates in the creating the product(s) but allows it to be formed easily. With this, it is now known that the rate of the reaction becomes relatively higher compared to the uncatalyzed reactions.
Therefore, the answer to this item is the rate of the reaction becomes faster.
Answer:
The average atomic mass is 126.1
Explanation:
To obtain the atomic mass of the isotope we use this formula;
(% composition of isotope 1 * mass number) + (% composition of isotope 2 * mass number)
1. Equate the percentage composition with the mass number of each isotope
45/100 * 125 = 56.25
55/100 * 127 = 69.85
2. Add both answers together you get,
56.25 + 69.85 = 126.1.
The average atomic mass is therefore 126.1
