Answer: The amount of energy lost by the metal is equal to the amount of energy gained by the water
Explanation:
The bond order of a diatomic element with six bonding electrons, six non-bonding electrons, and 2 anti-bonding electrons is 2 whose formula is( bonding electrons-anti bonding electrons)/2.
<h3>What is an element?</h3>
An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Answer:
D. The relationship between volume and moles
Explanation:
Amedo Avogadro found the relationship between the volume of a gas and the number of molecules contained in the volume.
The law states that "equal volume of all gases at the same temperature and pressure contains the same number of molecules or moles".
Mathematically:
V ∝ n (P,T constant)
Answer:The first method to determine the chemical composition of a substance in space was using light. By determining red shift in the observed spectrum of light they could determine the elements they were observing
