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:

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

Methane versus carbon dioxide are very important greenhouse gases. However, methane can retain and release about ____ times more

elixir [45]

The blank space in the task statement should be filled with 25 as methane can retain 25 times more heat than carbon dioxide.

<h3>Heat Retention: Methane and Carbon dioxide</h3>

Methane, carbon dioxide amongst other gases are important greenhouse gases which allows the Earth retain it's heat in order for it to be habitable.

Methane can retain and release about 25 times more heat than Carbon Dioxide although Methane emissions are lower compared to Carbon Dioxide.
