Explanation:
Oxides and their hydroxide counterparts made possible the industrial innovations we live in. Indeed, steel is a member of this family. Earth's crust contains them in vast quantities, making them the second most common element.
On a molecular scale, you would find that each oxygen atom is coupled with metal or semimetal atoms that fill in the gaps between them in oxide minerals. Oxides are divided into two groups: simple oxides, with a single metal or semimetal added, and complex oxides, where several metals can be incorporated into the molecule's structure. Hydroxides, on the other hand, are composed of metal ions attached to a highly reactive hydroxide ion (OH). Minerals formed by hydroxide are softer and less dense than oxides and usually form at lower temperatures.
Answer: B
Explanation: its natural gas so its repleinishable
Metamorphism would compare to a mineral that formed through evaporation
Answer:
7x10⁴.
Explanation:
Hello!
In this case, when rounding big number to a representation with less significant figures than it, we need to make sure we remove the spare figures and round up whether the next digit is five or more.
In such a way, for 74,000, we notice that 4 is not enough to round up the 7, that is why the number would contain a 7 only; moreover, to get rid of the thousand places, we need to introduce an exponent in 4 places, which means that the result would be:
7x10⁴.
Best regards!
