What things can the atomic radiation help us with

Chemistry

Chemotherapy is when radiation is used to kill cancer cells while sparing healthy tissue cells, also doctors sometimes inject patients with a nuclear tracer to show problematic areas that need to be checked out, and Nuclear power plants use nuclear energy to create a large amount of energy from just a small amount of Uranium. These are just some of the ways nuclear radiation is used to help us.

Pls help me with is question.​

Answer:

25cm³ = 0.025L of H2So4

Molarity of H2SO4 = 1moldm-³

Recall ... 1dm-³ = 1L

So the Molarity can also be 1mol/L

Mole = Molarity x volume in L

Mole of H2SO4 = 1mol/L x 0.025L

=0.025Moles of Sulphuric acid reacted.

From the equation of reaction

1mole of H2SO4 reacts to produce 1mole of Copper sulphate crystal

Since their Mole ratio is 1:1

It means that Since 0.025mole of H2SO4 reacted.... 0.025mole of CuSO4.5H2O would be produced

Nice.. OK

So we know the moles of CuSO4.5H2O produced

We can get the Mass

Recall

From

Mole=Mass/Molar Mass

Mass = Mole x Molar Mass

Molar Mass of CuSO4.5H2O = 64 + 32 + 16x4+ 5(2+16)

Mm= 250g/mol

Mass = 0.025mol x 250g/mol

= 6.25g of CuSO4.5H2O crystals Would be PRODUCED.

1. List three factors that can cause a chemical reaction to proceed faster.
Luba_88 [7]

Explanation:

1. The three factors are;

- Increasing the surface area of the reactants

- Using a catalyst

- Increasing temperature

2. Raising the temperature of a reaction mixture is the same as increasing the kinetic energy of the reacting molecules.

3. This reaction is an exothermic reaction. In exothermic reaction, the temperature of the system (mixture) decreases while that of the surroundings increases.

4. Reactions that releases energy to the surroundings are exothermic reactions.

5. All the options is an example of exothermic process because heat is being removed from the system except;

B. Evaporation of water - This is because it must absorb heat from the surroundings making it endothermic.
