Carbondioxide is a compound formed by burning of carbon and organic compound and it is a colorless and odorless gas.
O2 is the molecular form of Oxygen.
Cobalt(Co) is an element having atomic number 27 and mass number 59.
Is this a multiple choice? Anyways I will just give you a written answer and hopefully it helps.
A: Helium is made up of two electrons held by electromagnetic force to two protons that are inside of a nucleus along with one or two neutrons.
Answer:
some facts of rocks can be interesting but if you have to do it than you do it sorry but that's it goes
To solve for the solubility of this compound:Cu ^ + 2 + CO3 ^ -2 = [x] [x] = x^2 1.4 x 10 ^ -10 = x^2 x = 1.1832 x 10 ^ -5 1.1832 x 10 ^ -5 moles/ L x 123.526 g/mol (molar mass) is equals to 1.5 x 10 ^-3 g/L is the solubility of this compound - CuCO3.
Answer: Energy can be involved in disconnecting or connecting atoms to each other as the energy is used to break the bonds between the atoms ,so the reaction could proceed.
Explanation:<u> The statement can be well explained by the Planck's quantum theory , which states -:</u>
- In the form of small energy packets known as quanta of energy, energy is not released continuously, but discontinuously.
- The energy of each quantum is directly proportional to radiation frequency, i.e. E is directly proportional to v, where v is frequency E = hv, where h is the proportionality constant known as the constant of Planck.
- Any integer quanta will be the total energy of the radiation emitted or absorbed. Let the 'E' be the total radiation energy. So, when n is an integer, E'=nhv.
Hence, the given answer is based on the Planck's Quantum theory.
