concentration of the contact solution = 3 %

Explanation:

We have the following data:

10.7 g of hydrogen peroxide H₂O₂

355 g of solution

To calculate the concentration of the contact solution we use the following formula:

concentration = (mass of solute / mass of solution) × 100

concentration of the contact solution = (10.7 / 355) × 100

concentration of the contact solution = 3 %

What are the uses of carbon-14?
Gelneren [198K]

Carbon-14 is a radioactive isotope used to date organic material. Its consistent rate of decay allows the age of an object to be determined by the proportion of carbon-14 to other carbon isotopes. This process is called radiocarbon dating. Carbon-14 is also used as a radioactive tracer for medical tests.

Answer:

exothermic

Explanation:

This chemical reaction is an exothermic reaction because heat is liberated into the environment.

In organic chemistry, the reaction is termed a combustion reaction. In such a reaction, a fuel combines with oxygen to produce carbon dioxide and water.

It is an energy transformation from chemical energy to heat energy.

  • An exothermic reaction is one in which heat is liberated to the surrounding.
  • The surrounding becomes hotter at the end of the reaction.

In the reaction depicted, heat is liberated.

An aqueous solution of sodium
DochEvi [55]

Answer:

2.5×10^-7mol/dm^3

Explanation:

Firstly convert the cm^3 to dm^3

200×1000=200000dm^3

Calculate the g/dm^3

2/200000=0.00001g/dm^3

To calculate mol/dm^3

Mol/dm^3=mass given\molar mass

=0.00001/40

=2.5×10^-7mol/dm^3
