Write a balanced equation for the nuclear reaction in which neon-23 decays to form sodium-23

Chemistry

1 answer:

Bond [772]3 years ago

7 0

Explanation:

The nuclear reaction is a radioactive decay by the emission of a beta particle.

Beta emission increases the mass number of a nuclei.

A beta particle is a particle that closely resembles an electron. When a particle decays by emitting beta particles, the mass number remains the same but the atomic number increases.

Beta particle is designated as °₋₁β

²³₁₀ Ne ⇒ ²³₁₁Na + °₋₁β + energy

What is the concentration, in mass percent (m/m), of a solution prepared from 50.0 g nacl and 150.0 g of water?

Nataly [62]

Mass of solute ( m1 ) = 50.0 g

mass of solvent ( m2 ) = 150.0 g

Therefore:

m/m = ( m1 / m1 + m2 )

m/m = ( 50.0 / 50.0 + 150.0 )

m/m = ( 50.0 / 200 )

m/m = 0.25

How to solve 5gNaCl= MolE NaCl

valentinak56 [21]

0.086mole

Explanation:

The problem is very simple. It involves conversion from mass to number of moles of NaCl

What is mole?

A mole is a unit of measuring chemical substances. It is the amount that contains the avogadro's number of particles.

How is it related and can be converted from mass;

Number of moles of a substance = $\frac{mass}{molar mass}$

Since we know the mass, we can find the molar mass and put into this equation;

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Number of moles of NaCl = $\frac{5}{58.5} =$ 0.086mole

Consider the reaction.

Stella [2.4K]

Answer:

when the rates of the forward and reverse reactions are equal

Explanation:

In a chemical system, the reaction reaches a dynamic equilibrium when the rate of formation of product equals the rate of formation of reactants. This implies that both the forward and revered(backwards) reaction are occurring at the same rate.
