Answer: The correct answer is alpha particle.

Explanation:

There are 3 radioactive particles which are released in radioactive decay process:

1. Alpha particle: This particle is released when a nuclei undergoes alpha decay. The particle released has a mass of 4 units and has a charge of 2 units. The particle is positively charged.

_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}+_2^4\alpha

2. Beta-particle: This particle is released when a nuclei undergoes beta decay process. The particle released has a mass of 0 units and has a charge of (-1) units.

_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta

3. Gamma radiations: These radiations are released when an unstable nuclei undergoes gamma ray emission and gives excess energy by a spontaneous electromagnetic process. The radiations does not carry any charge and has no mass.

_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma

Hence, the radioactive particle that is charged charged and has two protons and two neutrons is the alpha particle.

What is the charge on the phosphorus atom in the polyatomic ion: PO4-3
oee [108]

+5

Explanation:

  The given radical is                 PO₄³⁻

To solve this problem, we need to understand what oxidation number entails.

The extent of the oxidation of each atom is expressed by the oxidation number.

Here are some rules for assigning them:

  • Elements in an uncombined state or elements that combines with one another, their oxidation number is zero.
  • The charge on an ion is its oxidation number
  • In an neutral compound, algebraic sum of all the oxidation numbers of all atoms is zero.
  • In a radical, the algebraic sum of all the oxidation numbers of the ions is equal to the charge on them.

Oxygen is known to have an oxidation number of -2;

                       

                          PO₄³⁻

 P + 4(-2) = -3

 P -8 = -3

  P = -3 + 8 = +5

The charge on phosphorus is +5

A cation is a metallic ion derived from base.Why is it derived from base?Can you derive it from an acid?
Scorpion4ik [409]

Answer:the cation can't be drived from an acid

Explanation:

Example

HCL+MgOH2=MgCl2+H2O

The cation in the salt magnesium chloride is magnesium which is derived from the base and the anion chlorine from the acid hydrochloric acid. The same is true in water.

What does Hess's law state about the total enthalpy change for a reaction?OA. It depends on the reaction pathway.B. It can only
Dimas [21]
<h2>Answer:</h2>

Option D is correct. It is independent of the reaction pathway.

<h2>Explanations:</h2><h2>What is Hess's law?</h2>

Hesslaw states that the enthalpy change of a reaction does not change regardless whether the reaction takes place in a single or multiple reaction pathways.

This shows that the total entalpy change of a reaction does not depend on the reaction pathway.
