Gamma rays

Explanation:

Every member of the electromagnetic radiation has commensurate amount of energy, wavelength and frequencies.

The electromagnetic waves with the shortest wavelengths and the highest frequencies are the gamma rays.

Gamma rays also are the most energetic electromagnetic radiation.
The short wavelength of gamma rays suggests that more waves passes with times.
It's high frequency shows that a high amount of wave passes through a point at each passing of time.
These factors combines to give its high energy. Energy of an electromagnetic radiation is a factor of its wavelength and frequency.
Gamma rays are ionizing radiations which causes ionization of gas molecules.

Is the chemical reaction between magnesium metal and hydrochloric acid solution an acid base reaction?

Anika [276]

Answer:

Explanation:

The chemical reaction between magnesium metal and hydrochloric acid solution is not an acid - base reaction.

An acid - base reaction involves an acid and base to produce salt and water.

This reaction is called a neutralization reaction.
An acid is a substance that produces excess hydroxonium ions in solutions.
A base produces excess hydroxyl ions in solution.
When acids and base combines, the main product is a salt in water solution.

What is the volume of an object with a density of 2.6 g/cm³ and a mass of 30.5g?

inessss [21]

Answer:

The answer is

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density}$

From the question

mass of object = 30.5 g

Density = 2.6 g/cm³

The volume is

$volume = \frac{30.5}{2.6} \\ = 11.7307692...$

We have the final answer as

Oksanka [162]

Answer: The partial pressure of $Cl_2$ is 1.86 atm

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_c$
