Write a nuclear balanced equation An atom of strontium-80 emits a positron

Chemistry

Answer:

₃₈Sr⁸⁰  →  ₃₇Rb⁸⁰ + ⁰₊₁e

Explanation:

Positron emission:

It is also called beta positive decay in which the neutron inside of the nucleus converted into the proton an thus emit the positron and electron neutrino which is called β particle.

Properties of beta radiation:

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiation

⁴₆C → ¹⁴₇N + ⁰₋₁e

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.  It is beta minus decay.

1. This is a combustion reaction.<span>

<span>Combustion reactions can happen with the </span>presence of O</span>₂ <span>gas. O₂<span> reacts with another element or compound and </span></span>oxidize<span> it. Here ethanol reacts with O₂<span> and produces </span></span>CO₂ and H₂O as products.<span> <span>Combustion is also called as </span></span>burning. <span>

2. Reaction will shift to right. <span>

3. The reaction will shift to right.</span><span>

</span><span>If the water is extracted from the system, the </span>amount of water will decrease. <span>That means the </span>amount of products decrease. Then the system will try to gain equilibrium by increasing the water. To increase water the forward reaction should be enhanced. <span>Hence, the</span> reaction will shift to right.<span>

4. The reaction will shift to right.

</span><span>This is an </span>exothermic reaction <span>since it </span>produces heat. If the produced heat is removed, then the system will be cold. To maintain the temperature, system has to increase the amount of heat produced. Then, the forward reaction should be enhanced. Hence, the reaction will shift to right.<span>

5. The Le Chatelier's principle.

</span>Le Chatelier's principle says if a condition changes in a system which was in an equilibrium state, the system will try to gain equilibrium by correcting the changed condition back to normal. Most of industries which make chemicals use this principle</span>

Judging by the electron domain geometry, which type of hybrid orbitals does this molecule have? s sp sp2 sp3
Aleksandr-060686 [28]
The molecule have TETRAHEDRAL HYBRID ORBITAL.
SP3 hybridization involves the mixing of one orbital of S sub level and three orbitals of P sub level of the valence shell. All the orbitals possess equivalent energies and shapes. The SP3 orbital has 25% S character and 75% P character. S and P refers to the s and p sub shells.<span />

What relationship exists between an enzyme and a catalyst?
shepuryov [24]

A catalyst is a chemical that increases the rate of a chemical reaction without itself being changed by the reaction. The fact that they aren't changed by participating in a reaction distinguishes catalysts from substrates, which are the reactants on which catalysts work. Enzymes catalyze biochemical reactions.

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.
