The density of a cube is 2.0gcm3. If the mass is 128 g, what is the length of each side of the cube?

kozerog [31]

Density = Mass / Volume

Volume = Mass/Density

Volume = 2/128

Volume = 1/64

so side will be 4 cm

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

77julia77 [94]

Answer:

For 1: The product is phosphoric acid and the solution is acidic in nature.

For 2: The product is sodium hydroxide and the solution is basic in nature.

For 3: The product is nitric acid and the solution is acidic in nature.

Explanation:

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:

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