Answer:
1. Aluminum oxide
2. Sodium chloride
3. Magnesium oxide
4. Calcium Chloride
Explanation:
Ionic compounds with only 2 elements all end with "ide" Use the full name of the element listed first and the second element with ide. Ex: Chlorine would become chloride.
Explanation:
bases can be either strong or weak
Money so i can get a nice body with the money hahah
S + O → SO -71kcal
Explanation:
The reaction describe is a thermochemical equation. In the reaction above, since heat is liberated, this is an exothermic reaction.
- In an exothermic change heat is liberated to the surroundings.
- At the end of the reaction, the surrounding becomes hotter.
- The value of the heat change is assigned a negative sign.
1 mol of liquid sulfur (S (l)) = S
1 mol of gaseous oxygen (O2 (g)) = O
gaseous sulfur dioxide (SO2) = SO
releasing 71kcal = -71kcal
S + O → SO -71kcal

A_r = 35.5
The average atomic mass of Cl is the <em>weighted average</em> of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its <em>% abundance</em>).
Thus,
0.7553 × 35 u = 26.4 u
0.2447 × 37 u = <u>9.05 u</u>
TOTAL = 35.5 u
