Predict the products of each reaction, and whether the solution at equilibrium will be acidic, basic, or neutral.1. P4O10 + 6H2O
77julia77 [94]

<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:

P_4O_{10}+6H_2O(l)\rightarrow 4H_3PO_4(aq)

(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:

Na_2O+H_2O(l)\rightarrow 2NaOH(aq)

(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:

3N_2O_5+3H_2O(l)\rightarrow 6HNO_3(aq)

An object has a density of 1.8 g/mL and a mass of 14 g. What is the volume of the object
lesya692 [45]

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!
