Identify which unknown was observed to be a basic salt (give the letter and chemical identity). Write the chemical reaction that is responsible for the increase in pH by this compound. Saved

The unknown compound is Na2CO3(Sodium carbonate).

Explanation:

The chemical compound Na2CO3 is known as Sodium carbonate. It has the value for Molar mass to be 105.9888 g/mol, the Density value to be 2.54 g/cm³ and the Melting point and boiling point values to be 851 °C and 1,600 °C respectively.

The chemical compound that is sodium carbonate is also known as the basic salt.

The chemical compound is also used in water softening and it is this process that causes the changes in pH value.

When added to water, the pH rises that is to say it becomes more basic.

The chemical reaction that is responsible for the increase in pH by this compound is given below;

Step one:

Na2CO3(s) > Na2CO3(aq).

Step two:

Na2CO3(aq) > 2Na^+ + CO3^2-.

Step three:

H2O + CO3^2- > OH^- + HCO3^-.

people flirt to show their affection towards someone in a less forward way then telling. they want the other person to guess what they’re feeling to have the other person also start to like them

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
