Which equation shows ejection of an alpha particle?

Chemistry

bija089 [108]2 years ago
4 0

In the third equation, the oxygen with atomic weight 16 undergo alpha decay and produce C₆¹³ . The alpha particle emitted is also called helium nuclei. During this decay some gamma radiations also produce as a byproduct.

<h3>What is Nuclear decay reaction ?</h3>

It is also called as radioactive decay during which an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements.

The atom emit the alpha particles consist of two proton and two neutrons. Which is also called Helium nuclei.

When atom undergoes the alpha emission the original atom convert into the atom having mass number 4 less than and atomic number 2 less than the starting atom.

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

Hence, the oxygen with atomic weight 16 undergo alpha decay and produce C₆¹³  and an alpha particle (He)

The pH of a 1.0M solution of butanoic acid HC4H7O2 is measured to be 2.41. Calculate the acid dissociation constant Ka of butano
Lubov Fominskaja [6]

Answer:

Ka = 1.52 E-5

Explanation:

  • CH3-(CH2)2-COOH ↔ CH3(CH2)2COO-  + H3O+

⇒ Ka = [H3O+][CH3)CH2)2COO-] / [CH3(CH2)2COOH]

mass balance:

⇒<em> C</em> CH3(CH2)2COOH = [CH3(CH2)2COO-] + [CH3(CH2)2COOH] = 1.0 M

charge balance:

⇒ [H3O+] = [CH3(CH2)2COO-]

⇒ Ka = [H3O+]²/(1 - [H3O+])

∴ pH = 2.41 = - Log [H3O+]

⇒ [H3O+] = 3.89 E-3 M

⇒ Ka = (3.89 E-3)² / ( 1 - 3.89 E-3 )

⇒ Ka = 1.519 E-5

The reaction takes place in water. What happens to the equilibrium when the pressure is increased? a)It favors formation of prod
OLga [1]

Answer:

I don't really get the options but it favoures the reactant side.

Explanation:

Increasing pressure favours the side with fewer moles of gas while decreasing pressure favours the side with the more moles of gas. E.g

If there is 0 moles of gas particles in the reactant side and 1 mole of gas particle in the product side, increasing pressure favours the reactants while decreasing pressure favours the product side.

With the explanations I have made, I hope the question is now clear to you.

Which is the best definition of nonpolar covalent bond?​
kondor19780726 [428]

Answer:

It is one of the covalent bonds in which the electrons are shared equally; therefore, dipole moment exists between the atoms in a molecule and there is no charge separation between the atoms in a molecule.
