(2) the mole ratios of the substances in the reaction
(3) the total number of electrons in the reaction
(4) the total number of elements in the reaction
The coefficients in a balanced chemical equation represent: (2) the mole ratios of the substances in the reaction.
A balanced chemical equation refers to an equation in which the number of atoms present on the reactant side (left) is the same or equal to the number of atoms present on the product side (right) of a chemical equation.
A coefficient can be defined as a number that is placed in front of a chemical symbol (formula) of an element or chemical compound in a chemical equation.

The frequency of the light emitted by the laser pointer is approximately 5.64 x 10ⁱ⁴ Hz, as calculated using the speed of light and the specific wavelength of the light.
To calculate the frequency of the light emitted by the laser pointer, you can use the equation c = fλ, where c represents the speed of light in vacuum (approximately 3.00 × 10⁸ m/s), f is the desired frequency, and λ represents the given wavelength of the light (in this case, 5.32 x 10⁻⁷ m).
By rearranging the equation to solve for frequency (f = c/λ), you can substitute in the given values: f = (3.00 × 10⁸ m/s) / (5.32 x 10⁻⁷ m), which yields a frequency of approximately 5.64 x 10ⁱ⁴ Hz. Therefore, the frequency of the light emitted by the laser pointer is about 5.64 x 10ⁿ⁴ Hz.
It's important to understand that light acts as a wave, and every color of light has a unique frequency, which correlates with its wavelength. The wavelength and frequency of light determine many its characteristics, including the color we perceive.

Explanation:
Reducing agent loses electrons
Answer:
An atom or, to be more specific, a helium atom.
Explanation:
This is a model of an atom. You can tell by the nucleus made only out of neutrons (the balls with no + or - sign) and protons (the balls with the + sign) and by the electrons (the balls with the - sign) circling around the nucleus.
This is a model of not just any atom, but a helium atom. An atom is defined by it's number of protons. For example, an atom with 1 proton is always hydrogen and an atom with 6 protons is always carbon. As you can see, this model has 2 protons. Any atom with 2 protons is a helium atom. This is a model of a helium atom.
