Answer:
0.9 moles of water
Explanation:
Use mole ratios:
5 : 6
divide by 5 on both sides
1 : 1.2
multiply by 0.75 on both sides
0.75 : 0.9
So the result is 0.9 moles of water

Answer:
A
Explanation:
CH3CH2COOH- Propanoic Acid
Explanation:
a) H2S (aq) + 2 O2 (g) → H2SO4(aq)
b) H2SO4 (aq) + CaCO3(s) → CaSO4 (s) + H2O (L) +CO2 (g)
To identify a redox reaction, we have to monitor the oxidation number of the elements to see if there is change.
In reaction (a);
The oxidation number of S increases from -2 (H2S) to + 6 (H2SO4). Also the oxidation number of O decreases from 0 (O2) to -2 (H2SO4). This is a redox reaction.
The oxidizing agent is O2 because it was reduced and the reducing agest is H2S.
In reaction (b);
There is no change in oxidation number in any f the elements. This is not a redox reaction.
One property that water and oil don’t have are that oils and fats not have any polar part and so for them to dissolve in water they would have to break some of waters hydrogen bonds
