As there was no electric charge on neutrons, and they did not get affected by electromagnetic fields.

Explanation:

The functions of the neutron in atoms is:

To hold the nuclei with coulombic repulsion between the protons.

The neutron has no charge on it and hence were not discovered.

Its mass is slightly less than the proton.

It provides stability to the atom.

Lord Chadwick is credited to prove the existence and discovery of neutron.

He proved that the nucleus of the atom has its mass in the centre as neutron+ proton.

He bombarded beryllium with alpha particles, and found high energy radiation.

if the percent yield ofr the following reaction is 75% and 45.0g of NO2 are consumed with ercess water in the reaction. how many
NISA [10]

Answer:

30.8 grams of nitric acid are produced

Explanation:

Let's state the reaction:

3 NO₂ + H₂O → 2 HNO₃ + NO

If water is the excess reagent, then the limiting is the gas.

We convert the mass to moles:

45 g . 1 mol/ 46 g = 0.978 moles

Ratio is 3:2. 3 moles of gas can produce 2 moles of acid

Then, 0.978 moles may produce (0.978 . 2) /3 = 0.652 moles of acid

This is the 100% yield, but in this case, the percent yield is 75%

0.652 moles . 0.75 = 0.489 moles

Let's convert the moles to mass → 0.489 mol . 63g / 1mol = 30.8 g
