How many protrons are in 12 carbon isotopes​

Chemistry
1 answer:
Snezhnost [94]3 years ago
4 0

Answer:

The different forms of an element based on the number of neutrons in the nucleus are called "isotopes." Carbon-12 is only one isotope of the element carbon, with 6 protons and 6 neutrons. There are also carbon-13, with 6 protons and 7 neutrons, and carbon-14, with 6 protons and 8 neutrons.

what is the pH of a solution that has a hydronium ion concentration 100 times greater than a solution with a pH of 4
Anna71 [15]

Answer:

2

Explanation:

First, find the hydronium ion concentration of the solution with a pH of 4.

[H₃O⁺] = 10^-pH

[H₃O⁺] = 10⁻⁴

[H₃O⁺] = 1 × 10⁻⁴

Next, multiple the hydronium ion concentration by 100 to find the hydronium ion concentration of the new solution.

[H₃O⁺] = 1.0 × 10⁻⁴ × 100 = 0.01

Lastly, find the pH.

pH = -log [H₃O⁺]

pH = -log (0.01)

pH = 2

The pH of a solution that has a hydronium ion concentration 100 times greater than a solution with a pH of 4 is 2.

Hope this helps.

How are the energy and wavelength of electromag<br> netic radiation related?
tia_tia [17]

Answer:

Electromagnetic radiation is a form of energy that is produced by oscillating electric and magnetic disturbance, or by the movement of electrically charged particles traveling through a vacuum or matter. The electric and magnetic fields come at right angles to each other and combined wave moves perpendicular to both magnetic and electric oscillating fields thus the disturbance. Electron radiation is released as photons, which are bundles of light energy that travel at the speed of light as quantized harmonic waves. This energy is then grouped into categories based on its wavelength into the electromagnetic spectrum. These electric and magnetic waves travel perpendicular to each other and have certain characteristics, including amplitude, wavelength, and frequency.

General Properties of all electromagnetic radiation:

Electromagnetic radiation can travel through empty space. Most other types of waves must travel through some sort of substance. For example, sound waves need either a gas, solid, or liquid to pass through in order to be heard.

The speed of light is always a constant. (Speed of light : 2.99792458 x 108 m s-1)

Wavelengths are measured between the distances of either crests or troughs. It is usually characterized by the Greek symbol  λ .

What are the coefficients for the reaction _Cl2O5 + _H2O → _HClO3 once it is balanced?
Eva8 [605]
It is B (1,1,2) because when you plug those numbers in, there are the same amount of elements in the reactant and product, just rearranged as the format A+B <span>→  AB, because this is a synthesis reaction.</span>
