There are 6 electrons for Co2-
Answer:
(C) Only particular quantized energies are given off by excited electrons in the form of light.
Explanation:
Atomic emission spectra often have gaps that help to create the color lines.
These gaps occur as a result of heat energy absorbed by electrons in the atoms, making them to be excited and allow them to jump into higher energy levels by emitting only particular quantized energies in the form of light.
Therefore, the correct option is "C"
(C) Only particular quantized energies are given off by excited electrons in the form of light.

Explanation:</h3>
SI units relate to the International System of Units. These units are the base, metric units that are most commonly accepted for different measurements.
Common SI Units
The most common SI units are as follows:
- Length - meter (m)
- Time - second (s)
- Mass - kilogram (kg)
- Amount of substance - mole (mole)
- Electric current - ampere (A)
- Temperature - kelvin (K)
- Volume - liter (L)
*Note that gram (g) is not an SI unit
Each type of measurement will only have 1 SI unit. This is the unit that will be expected for most answers. Sometimes this means converting an answer into a different unit so it is more widely accepted.
Why SI Units are Important
SI units are important for the same reason that the metric system is used. It gives a standardized list of measurements that scientists across the world can use. Also, it makes it easier to compare scientific findings and studies when all of the measurements are given in the same units.
There are times when it is unrealistic to use SI units. For example, when discussing space, using meters will not be realistic due to the size of space. Also, when measuring the mass of small elements, kilograms are too large. But otherwise, SI units should be used.
Answer:
1: New atoms are formed as products
Explanation:
matter (atoms) cannot be created or destroyed
unless you are God or Cinderella's fairy Godmother or something
Explanation:
Expresa los gramos de soluto por cada 100 gramos de disolución. Porcentaje masa = masa de soluto___ x 100 masa de la disolución Cuando trabajamos con la masa, podemos sumar el soluto y el disolvente para obtener la disolución.
