Kelvin = C + 273.15
Kelvin and Celsius will be ranked the same because the temperature change is the same. Kelvin is just set at a different zero point.
Fahrenheit has the largest range which you can see by the freezing (32F) and boiling (212F) point of water. (212-32 = 180) Whereas the temperature change going from freezing to boiling water for both Kelvin and Celsius is 100. This means that one degree Fahrenheit feels smaller and should be ranked least.
Answer:
"c" is the element with the most negative electron affinity.
Explanation:
We can obtain the following information from the electron configuration:
Period: Is the level in which the differential electron is in.
Group: Is the sum of all electrons in the last level.
Knowing their ubication in the periodic table, we can classify them as metals, nonmetals or noble gases.
a. 5s² P: 5 G: IIA (2) Metal
b. 5s²5p² P: 5 G: 2 + 2 = IVA (14) Nonmetal
c. 5s²5p⁵ P: 5 G: 2 + 5 = VIIA (17) Nonmetal
d. 5s²5p⁶ P: 5 G: 2 + 6 = VIIIA (18) Noble gas
Noble metals have a low tendency to gain electrons so their electron affinity is neglectable. For elements in the same period, the electron affinity gets more negative from left to right. Therefore, "c" is the element with the most negative electron affinity.
Answer;
C. Decomposition of water
Explanation;
A decomposition reaction occurs when one reactant breaks down into two or more products.This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
The equation for the decomposition of water; 2H2O --> 2H2+O2
2 H2 + O2 = 2 H2O
1 mole O2 --------------- 2 moles H2O
13.35 moles O2 -------- ( moles H2O)
moles H2O = 13.35 x 2 / 1
<span>= </span>26.7 moles of H2O
