Answer:
Explanation:
This question is asking to convert a measurement in kilometers to meters
<u>Answer:</u>
<u>For 1:</u> The product is phosphoric acid and the solution is acidic in nature.
<u>For 2:</u> The product is sodium hydroxide and the solution is basic in nature.
<u>For 3:</u> The product is nitric acid and the solution is acidic in nature.
<u>Explanation:</u>
For the given options:
(1): When diphosphorus pentoxide reacts with water, it leads to the formation of phosphoric acid, which makes the solution acidic in nature.
The chemical equation for the reaction follows:

(2): When disodium oxide reacts with water, it leads to the formation of sodium hydroxide, which makes the solution basic in nature.
The chemical equation for the reaction follows:

(3): When dinitrogen pentoxide reacts with water, it leads to the formation of nitric acid, which makes the solution acidic in nature.
The chemical equation for the reaction follows:

Answer:
0.13 cm^3
Explanation:
Volume = Mass/ density
1.8 g/ml / 14g = 0.128571429
Both numbers have 2 significant digits.
With that, the answer rounds to 0.13
The final answer is 0.13 cm(don't forget the units for volume)
Hope it helped!
