The most appropriate answer is D ! temperature !
as when temperature increases KE increases and the collision factor and frequency increases !
Answer:
MgN3
Explanation:
In MgN3 the charge on the ionic species is greater than NaCl. So,ionic interactions in MgN3 will be stronger
Answer:
+6
Explanation:
We are given;
We are required to determine the oxidation number of S in the compound.
We need to know that;
- The total oxidation number of this compound is Zero
- Oxidation number of Ba metal is +2
- Oxidation number of Oxygen atom is -2
- There is 1 atom of Ba, 1 atom of S and 4 atoms of O in the compound.
Therefore; assuming oxidation number of S is x
Then, (1× 2) + (1 × x) + ( 4 ×(-2)) = 0
2 + x - 8 = 0
x = 6 or +6
Thus oxidation number of Sulfur in BaSO₄ is +6.
I think the answer is b the second one
