Max Planck concluded that energy is not continuous and is carried in discontinuous units which he named quanta.
Yes, the chemical reaction occurs because new substance is formed and heat energy is released.

What is chemical reaction?</h3>
Chemical reaction is a process in which one or more substances i.e. the reactants, are converted to one or more different substances i.e. the products so we can conclude that the chemical reaction occurs because new substance is formed and heat energy is released.

An ionic compound is formed between a metal and a non metal. The metal being electropositive can form a cation by transferring the electron to the electronegative non metal that gains the electrons to form an anion. Both the elements try to get a stable octet configuration by the transfer of electrons. The number of electrons lost by metal will be equal to the number of electrons gained by the non metal. Hence, the magnitude of positive charge on the cation will be equal to the magnitude of negative charge on the anion. Therefore, the overall charge on the compound will be 0
So the correct answer is the sum of all charges in the formula for an ionic compound is 0
Answer:
The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
Answer:
A. a poisonous gas is one of the reactants
Explanation:
Chlorine gas is a poisonous and very toxic gas. Chlorine is a moderately reactive halogen. It is a greenish-yellow gas with choking and irritating smell. The gas is very poisonous. Proper care must be taken when working with this gas.
This is why chlorine gas are harmful in production of fireworks.
