As metal + acid will form hydrogen gas and salt , the chemical equation is :
Mg + 2HCl --> H2 + MgCl2
Answer:
homogenous
Explanation:
its a pure element, so it is a pure substance
Either covalent or ionic... they are nonmetals meaning that the are a component in both types of compounds
MAGNESIUM IS HIGHER IN THE REACTIVITY SERIES.
Explanation:
The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities.
The reactivity series provides information whether a metal can displace another in a single displacement reaction. It can also be used to obtain information on the reactivity of metals towards water and acids.
Magnesium reacts very slowly with cold water, but rapidly in boiling water, and very vigorously with acids.
Titanium reacts with concentrated mineral acids, pyrometallurgical extraction using magnesium, or less commonly other alkali metals, hydrogen or calcium in the Kroll process
.
Answer: Option (c) is the correct answer.
Explanation:
When two substances does not exchange any energy with each other then they are said to be in thermal equilibrium with each other.
This means the temperature of both the substances will be equal, that is why, there is no exchange of energy between them.
Thus, we can conclude that when the objects have the same temperature then you can tell the two objects are in thermal equilibrium.
