Answer:

There are certain particles or packets or energy which are generated each time there is some imbalance inside the atomic structure of an atom. As there are a unique number or electrons and protons inside the atoms which however remains the same until some sort of effects or force tends them to dislocate from there position of equilibrium.

  • That is how when an external source is there for an atom (having the characteristics of radiation), there is a net change of the neutral particles into the positrons which tends the whole system inside the atom to attain a balance state. Because it is not possible for an atom to have an unequal number of positrons and electrons on it.
  • And, this effect of conversion inside the atomic structure tends the electrons in the outer shells to move far from the nucleus and at last they are made free while have a net speed they can easily penetrate through a number of mediums.
  • So, we can just say that the Beta particles is another term used for the detached number of electrons from the nucleus which travels in a more specific path or route, as each atom or molecule requires a level of electronic stability on it. So, it has net -1 charge on it, while being an electron with a high level of velocity and energy its mass, m becomes zero in total.
  • While, the transmission of such detached electrons from a given nucleus is termed as the release of electromagnetic energy inside a given space or medium.

A beta particle is an electron and it has a -1 charge and zero mass.

Beta decay by emitting an electron is called as β⁻ decay. When this happens, a neutron of the element converts into a proton by emitting an electron. Hence, the mass of daughter nucleus is same as parent atom but atomic number/number of protons is higher by 1 than atomic number of parent atom.

In a β⁻ decay, the symbol is used as ₋₁⁰β or ₋₁⁰e.
             -1 is for charge
<span>              0 is for the mass of the particle

In a chemical reaction how does the mass of the reactants compare with the mass of the products?
Juli2301 [7.4K]

Answer:

The mass of the reactants compared with the mass of the products should be the same if the reactants are in stoichiometric amounts.

Explanation:

In this question, they ask about chemical reactions and the comparison of the mass of reactants and products. Firstly, it is necessary to introduce the mass conservation principle.

Mass conservation principle mentions that in a chemical reaction, the total mass of reactants is equal to the total mass of products (if the reaction is fully developed). It means mass is not created or destroyed, only transforms from reactants to products.

For example, the mass of sodium plus the mass of chlorine that reactswith the sodium equals the mass of the product sodium chloride.Because atoms are only rearranged in a chemical reaction, there mustbe the same number of sodium atoms and chlorine atoms in both thereactants and products.

Finally, we can conclude that The mass of the reactants compared with the mass of the products should be the same if the reactants are in stoichiometric amounts.

I need help with the first question
gregori [183]
Zn⁰ ----> Zn⁺²   +   2e⁻ -  oxidation
Hg⁺² + 2e⁻ ----> Hg⁰ - reduction

Zn loses 2 moles of electrons , and Hg gains 2 mole of electrons.
So, number of moles of electrons gained and lost during reaction is equal.

What portion of your salt solution in ice water system is: a. A mixture? b. A solution?
ahrayia [7]

The salt and water are a homogeneous mixture but when salt dissolves in the water system is called a solution of salt and water.

<h3>What is a mixture? </h3>

A mixture is defined as the combination of two or more substances that are not chemically bonded together.

There are two types of mixture which include:

  • Homogeneous (uniform composition) and

  • Heterogeneous mixtures

When salt is added to the ice water system, it lowers the freezing point of the ice water thereby forming a homogenous mixture of water and salt.

The dissolution of salt in ice water leads to the formation of salt and water solution.

1. Addition of which of the following will increase the solubility of CaCO3 in water? Consider the equilibrium process:
kolbaska11 [484]

Answer: HCl

Explanation:

calcium carbonate dissolves in HCl acid producing CO 2 gas. It will not dissolve in pure water. The Ksp for calcium carbonate in water is 3.4 x 10-9 moldm-3 which is very low. What takes place here is actually a chemical reaction:

CaCO 3 (s) + 2HCl(aq) → CaCl 2 (aq) + H 2CO 3(aq)

This reaction accounts for the solubility of the Calcium carbonate in HCl and not in pure water.
