Answer:

See explanation

Explanation:

The shorthand nuclear reaction equations have been given; the first particle in the parentheses is a reactant particle while the second particle is a product particle. These can now be rewritten as the longhand equations as follows;

238/92U + 4/2 He -------> 241/94Pu + 1/0 n

238/92U + 4/2 He ------> 241/94Pu + 1/0 n

14/7N + 4/2 He------> 17/8O + 1/1 p

56/26Fe + 2 4/2 He----> 60/29Cu + 4/2 He

If 6.02*10^23 molecules of ammonia react with 12.04*10^23 molecules of hydrogen chloride, how many molecules are in the reaction

Helen [10]

Answer:

18.06 × 10²³ molecules

Explanation:

Add the two amounts of molecules together.

6.02 × 10²³ + 12.04 × 10²³ = 18.06 × 10²³

You will have 18.06 × 10²³ molecules in the vessel when the reaction is complete. This is because of the Law of Conservation of Mass. Mass is neither created nor destroyed in chemical reactions. You will have the exact number of molecules in the reaction vessel as you did in the beginning. The types of molecules may change, but the number will stay the same.

How many atoms are there in 10.2 moles of Phosphorous?

nikdorinn [45]

There are 2.06 x 10²⁴ atoms

<h3>Further explanation </h3>

The mole is the number of particles (atoms, molecules, ions)contained in a substance

1 mol = 6.02.10²³ particles

Moles can also be determined from the amount of substance mass and its molar mass
