One mole of a substance contains 6.02 × 1023 protons and an equal number of electrons. If the protons could somehow be separated

from the electrons and placed in very small, individual containers separated by a million meters, what would be the magnitude of the electrostatic force exerted by one box on the other?

Magnesium is a highly flammable element which is easily combustible in the presence of oxygen:
NemiM [27]

4 atoms

Explanation:

On the product side, we expect to find 4 atoms of the product.

    An atom is the smallest indivisible particle that takes part in a chemical reaction.

    An element is a distinct substance that cannot be split-up into simpler substances. Such substances consist of only one kind of atom.

    In this reaction we have:

       2 elements:             Mg                O

on the reactant side:

   We have two moles of Mg:   2 atoms of Mg

            1 mole of oxygen gas:   2 atoms of O

                             total atoms:    4 atoms

According to the law of conservation of matter "in a chemical reaction, matter is neither created nor destroyed".

We expect to find 4 atoms of products which is MgO on the product side.

              2Mg + O₂ →  2MgO + heat

Sphinxa [80]

Explanation:

you measure temperature in degrees celsius using a thermometer. Thermal energy is measured in joules. A larger volume of water will take longer to heat up but will store more energy than the smaller object. However, a smaller object will lose it's heat faster than a larger object. A cup of tea has less thermal energy than a swimming pool.
