the radioactive particle that is positively charged and has two protons and two neutrons is the _____. alpha particle beta particle gamma ray neutron

Answers

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.

it is the alpha particle

Which of the following is a change from a less condensed to a more condensed state of matter?A.) Boiling
B.) Evaporating
C.) Condensation
D.) Melting

Answers

The answer is C. Condensation is a change from a less condensed to a more condensed state of matter. It is a phase change from the gas state to liquid state. The gas is the less condensed state and the liquid is the more condensed state as compared to gas.

In terms of molecular motion, why does an increase in pressure lead to an increased solubility of a gas?

Answers

We imagine a piston cylinder and a solution of gas and water. Molecules are in constant random motion and some of the gas particles are in the vapor phase while some in the liquid phase. At a specific volume, molecules move freely. However, when the piston is moved down, increasing the pressure, some of the molecules in the vapor are pushed down to the liquid phase in order maintain equilibrium thus increasing solubility

Metals experience plastic deformation when _____.

Answers

Metals experience plastic deformation when a specific amount of pressure and temperature is applied to them. Most metals have low specific heat. Because of their low specific heat, they easily get hot when heat is applied to them.

A chemist has dissolved a certain substance in water. The chemist knows that more of the substance could be dissolved into the water before it stops dissolving. Therefore, the current solution is

Answers

Answer is: the current solution is unsaturated.

Unsaturated solution means that more of a substance can be dissolve.

For example:

Solubility of potassium chlorate (KClO₃) at 100 grams of water at 80°C is 37.5 g, that means that all 37.5 g is completely dissolves, this is the saturated solution.

If we add 20 grams of potassium chlorate in 100 grams of water, there is less solute than the saturated solution, so this is unsaturated solution.

The current solution is $\boxed{{\text{unsaturated}}}$ .

Further explanation:

The maximum amount of solute particles that can be dissolved in fixed amount of solvent to form a saturated solution is called solubility of a salt. The units of solubility are often expressed as ${\text{g}}/100{\text{ mL}}$ . Depending upon solubility the solution can be of three types:

1. Saturated solution

2. Unsaturated solution

3. Supersaturated solution

The saturated solution may be defined as a solution that has maximum amount of solute dissolved and that cannot accommodate any further solute. Such a solution has some undissolved substance at the bottom.

The unsaturated solution may be defined as the solution in which the solute concentration is smaller than the maximum amount that can be added and hence more amount can be easily added.

The supersaturated solution refers to the solution in which the solute concentration exceeds the maximum amount that can be added. Such a solution is prepared when a solution is heated to a certain temperature to dissolve this solute and then slowly cooled down to lower temperatures.

Since more solute can still be dissolved in the solution hence the current solution is unsaturated.
