Answer:

The answer is adding a proton to the nucleus.

Explanation:

The answer is adding proton to the nucleus.

Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.

There are two types of beta decay: beta minus and beta plus.

In beta plus decay, a proton is converted to a neutron, positron and an electron neutrino, so mass number does not change.

In beta minus decay (atomic number Z is increased by one) neutron is converted to a proton and an electron and an electron antineutrino.

For example, nuclear reaction:

²⁶Na → ²⁶Mg + e⁻(electron) + ve(electron antineutrino

Balance the equation by inserting coefficients as needed. equation: ZnS + HBr -> ZnBr_{2} + H_{2}S ZnS + HBr ⟶ ZnBr 2 + H 2 S

yawa3891 [41]

Answer : The balanced chemical reaction will be,

$ZnS+2HBr\rightarrow ZnBr_2+H_2S$

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

The given chemical reaction is,

$ZnS+HBr\rightarrow ZnBr_2+H_2S$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen bromine atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the $HBr$ and we get the balanced chemical equation.

The balanced chemical reaction will be,

$ZnS+2HBr\rightarrow ZnBr_2+H_2S$

Will reward brainliest Explain why all arrhenius acids can be considered bronsted lowry acids

GuDViN [60]

Answer:

Explanation:

A bronsted lowry acid just means that it donates a proton.

An arrhenius acid dissolves in water to donate a proton

the only difference is that an arrhenius acid must dissolve in water but it still donates a proton so it is considered a bronsted lowry acid
