The nuclear emission that is negatively charged is \boxed{{\text{2}}{\text{. a beta particle}}}.

Further Explanation:

Radioactive decay:

Also known as nuclear decay, radioactivity, nuclear or radioactive disintegration. It is the process due to which an unstable atomic nucleus releases its energy in the form of various particles such as alpha particles, beta particles, and gamma particles.

Following are the types of radioactive decays:

1. Alpha decay

In this decay, alpha particles are emitted by unstable nuclei. An alpha particle is a helium nucleus with two protons and two neutrons. It has a charge of +2. The general equation for an alpha decay is as follows:

_{\text{Z}}^{\text{A}}{\text{X}} \to _{{\text{Z - 2}}}^{{\text{A - 4}}}{\text{X}} + _{\text{2}}^{\text{4}}{\text{He}}

2. Beta decay

In this decay, beta particles are produced. This occurs when the nucleus decays continuously and emits an electron or a positron. The general equation for beta decay is as follows:

_{\text{Z}}^{\text{A}}{\text{X}} \to _{{\text{Z + 1}}}^{\text{A}}{\text{X}} + _{{\text{ - 1}}}^{\text{0}}{\beta }}

Beta decay is further classified as follows:

(a) {\beta }}^-} decay: In this decay, an electron and an electron antineutrino are emitted. The atomic number of the element is increased by one. Its general equation is as follows:

_{\text{Z}}^{\text{A}}{\text{X}}\to _{{\text{Z+1}}}^{\text{A}}{\text{X}}+{e^-}+{\mathop{\text{v}}\limits^-_{\text{e}}}

(b) {\beta }}^+} decay or positron emission: In this decay, a positron and an electron neutrino are emitted. The atomic number of the element is decreased by one. Its general equation is as follows:

_{\text{Z}}^{\text{A}}{\text{X}} \to _{{\text{Z}} - 1}^{\text{A}}{\text{X}}+{e^+}+{{\text{v}}_{\text{e}}}

3. Gamma decay

In this decay, gamma rays are emitted. Energy is emitted during gamma decay but the number of protons remains unaltered. The general equation for gamma decay is as follows:

_{\text{Z}}^{\text{A}}{\text{X}} \to _{\text{Z}}^{\text{A}}{\text{X}} + _{\text{0}}^{\text{0}}{{\gamma }}

4. Neutron emission

It is the type of radioactive decay that occurs when one or more neutrons are ejected from a nucleus. Neutrons are the subatomic particles with no charge. Since only neutrons are removed from the atom, the number of protons as well electrons remain unaltered. This results in the formation of an isotope of the same element.

Therefore the negatively charged nuclear emission is a beta particle because an electron that is a negatively charged species is lost in {\beta }}^-} decay, a type of beta decay.

What is the oxidation number for iodine in Mg(IO3)2 ?
navik [9.2K]
The oxidation number of iodine is 5 in Mg(IO3)2 which can be calculated as 
   Mg(IO3)2
   MgI2O6
As we know that
Mg has +2
O has -2
So,
   (+2) + 2I + 6 (-2)=0
   2 + 2I - 12 =0
   10+ 2I =0
    10 = 2I
     I =5

Reason why chemistry is studied
mina [271]

Answer: Chemistry is the study of change. Various reasons why to study Chemistry is to appreciate the fundamentals of the world such as the composition of all living thing. We are made up of matter. The interaction of sub atomic particles in an atom to form a single being. Also to understand how certain chemicals are beneficial and harmful in our lives just by reading product labels.

For the reaction 2A(g) â B(g), the equilibrium constant is Kp = 0.76. A reaction mixture initially contains 4.0 atm of gas (PA =
timofeeve [1]

Answer: (a) The reaction mixture will proceed toward products.

Explanation:

Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as K_p

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

2A(g)\rightleftharpoons B(g)

The expression for Q_p is written as:

Q_p=\frac{p_B}{(p_A)^2}

Q_p=\frac{(2.0)}{(2.0)^2}

Q_p=0.5

K_p=0.76

Thus as K_p>Q_p , the reaction will shift towards the right i.e. towards the product side.

Find the formula for the hydrate<br>0.737 g MgSO3 and 0.763 g H2O
babunello [35]

The required formula of hydrate is MgSO₃.6H₂O.

<h3>How do we calculate the formula of hydrate?</h3>

The number of moles of water per mole of anhydrous solid (x) will be computed by dividing the number of moles of water by the number of moles of anhydrous solid (x) to find the hydrate's formula.

Moles will be calculated as:
n = W/M, where

  • W = given mass
  • M = molar mass

Moles of MgSO₃ = 0.737g / 104.3g/mol = 0.007mol

Moles of H₂O = 0.763g / 18g/mol = 0.04 mol

Number of H₂O molecule = 0.04/0.007 = 5.7 = 6

So formula of hydrate is MgSO₃.6H₂O.

Hence required formula of hydrate compound is MgSO₃.6H₂O.
