Mg (magnesium) reacts with acids and Produces magnesium salt and hydrogen gas as the products.
Followings are some balanced reactions of Mg with acids.
Mg(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂(g)
Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g)
Mg(s) + 2HNO₃(aq) → Mg(NO₃)₂(aq) + H₂(g)
It is an example of physical change. The molecules are not changing, so it is not chemical, and a physical property is something that a physical thing has.
Answer:
The answer is the heat is transferred from the ice to the coffee.
Explanation:
Hot molecules tend to transfer to colder molcules, which causes the ice to melt and makes the coffee colder.
Hope this helps! :)
Polyethylene terephthalate commonly abbreviated as PET
The answer is; C
The radioisotopes in the interior of the earth are not in pure form and have many embedded impurities and are interspersed. Therefore when a neutron is released by a decaying atom, its chances of hitting another radioisotope atom (to continue the chain reaction) are lower than in a manmade nuclear reactor. This way, the radioactive chain reaction in the earth’s interior is not well sustained.
