Converting carbon to nitrogen by increasing the number of protons from 6 to 7 and decreasing the number of neutrons from 8 to 7 is an example of what type of decay?

Answers

Answer: The given decay process is beta decay.

Explanation:

Beta-decay is defined as the decay process in which a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units and has a mass of 0 units.

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

The chemical reaction for converting carbon nucleus to nitrogen nucleus, the equation follows:

$_6^(14)\textrm{C}\rightarrow _7^(14)\textrm{N}+_(-1)^0\beta$

Thus, the given decay process is beta decay.

this is beta decay as the mass number stays the same but proton number changes, this is specifically beta minus as a neuron changes into a proton

The smallest part of an element that can still be identified as that element is a(n) _____. (A) molecule
(B) proton
(C) electron
(D) atom

Answers

Answer:

atom

Explanation:

(A) molecule is the a group of atoms which are bonded together,

(B) proton it is a particle that comprise an atom

(D) atom is the smallest part of an element that can still be identified

Hence the correct answer is D. The smallest part of an element that can still be identified as that element is an atom.

Answer:

(D) atom

Explanation:

The atom is the smallest unit of matter that has the properties of a chemical element.

The atom is composed of protons, electrons, and neutrons, they are subatomic particles.

Each chemical element has an atom that identifies it, but all atoms are composed of subatomic particles, this means that all atoms have electrons, neutrons, and protons.

Depending on the number of subatomic particles that we have is what gives the properties to each atom.

Josh prepares a solution by mixing sodium nitrate with water. To calculate the molarity of the solution, josh should calculate the moles of which substance,and why?

Answers

There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. Josh should calculate the moles of the sodium nitrate by dividing the mass with the molar mass of sodium nitrate. This is because it is the solute in this problem.

Answer:

the answer is sodium nitrate because it is solute

Explanation

thats what is correct I assure you.

Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) 2NH3(g) What occurs when the concentration of H2(g) is increased?

Answers

Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) = 2NH3(g). When the concentration of the hydrogen gas is increased, the equilibrium will tend to go to the products or to the forward reaction. Therefore, more products are formed.

Would the two as yet undiscovered elements A+1 and D+2 react?

Answers

Answer: No, the given elements will not react.

Explanation:

Ionic bond is defined as the bond which is formed from the complete transfer of electrons from one atom to another atom. The atom which looses electrons is known as electropositive atom and it attains positive charge. The atom which gains electrons is known as electronegative atom and it attains negative charge. For Example: KBr

Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms forming a bond. No ions are present in the compound. For Example: HCl

We are given, two elements with their oxidation states:

$A^+\text{ and }D^(2+)$

As, both the ions are positive ion and thus, will not react to form any compound because like charges repel each other.

Hence, no, the given elements will not react.

The best answer is no bc the question ask "Would the two as yet undiscovered element A+1 and D+2" don't sound right

In chemistry, there are three commonly encountered theories to explain what acids and bases are and what they do. Name these theories and describe what each one states about acids and bases. Give an example to help describe each of the types. Make sure to explain how these theories differ from each other. (Properties of Acids and Bases)

Answers

Answer: The theories are such that if any chemical produce H+ ion then it is an acid and if the chemical produces OH- ion then it's a base.
