Answer:
Metallic compound
Explanation:
Metallic compound -
A metallic compound refers to the species having at least one metal, is known as a metallic compound.
In general a metallic compound consists of two ions, a positive ion or the cation, is is basically a metal, and,
a negative ion or an anion, which is a non - metal.
Hence, from the given statement of the question,
The correct answer is - metallic compound.
A Thermochemical Equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH. In variable form, a thermochemical equation would look like this:
A + B → CΔH = (±) #
Where {A, B, C} are the usual agents of a chemical equation with coefficients and “(±) #” is a positive or negative numerical value, usually with units of kJ.

The answer is 40.
We can solve this by finding out the number of protons, and neutrons. Atomic number of an element means the number of protons in that element. So, the atom has 30 protons if the atomic number is 30.
On the other hand, mass number is the total number of protons and neutrons, but not electrons, because they're too light comparing to the other 2. Therefore, we can simply solve the number of neutrons in the atom by subtracting the number of protons from the mass number. 70 - 30 = 40.
Therfore, the number of neutrons is 40.
