The Solvay process is a multistep industrial process used to produce washing soda, Na2CO3(s). In the last step of the Solvay process, NaHCO3(s) is heated to 300°C, producing washing soda, water, and carbon dioxide. This reaction is represented by the balanced equation below.2NaHCO3(s) + heat ==> Na2CO3(s) + H2O(g) + CO2(g)

Write the IUPAC name for washing soda.

Answers

Answer 1
Answer: Its IUPAC name is sodium carbonate. It is also known as soda ash. It is the water soluble sodium salt of carbonic acid and occurs as a crystalline heptahydrate. Sodium carbonate has an alkaline taste and when in solution forms a basic solution. One important application is that it is used commonly as a water softener.

The atomic mass of an element can be approximated by adding the number of _______ plus the average number of _______.A. protons; electrons

B. protons; neutrons

C. neutrons; electrons

Answers

Answer: Option (B) is the correct answer.

Explanation:

Atomic mass is defined as the summation of total number of protons and neutrons present in an element.

On the other hand, atomic number means the total number of protons present in an element.

For example, atomic number of sodium is 11 and number of neutrons present in it are 12.

Hence, atomic mass of sodium = no. of protons + no. of neutrons

                                                    = (11 + 12) amu

                                                    = 23 amu

Therefore, we can conclude that the atomic mass of an element can be approximated by adding the number of protons plus the average number of neutrons.
by adding number of protons and neutrons

Where does the equilibrium point occur in a reaction system

Answers

The equilibrium point for a reaction is the point at which the rate of the forward reaction equals that of the reverse reaction.  At this point there will  not be a net change in the amount of products or reactants observed.
