Answer:
(C) knowing which minerals are in a rock can help you identify and classify that rock.
Explanation:
It is the truth.
Answer:
Explanation:
We can start with the <u>reaction of hydrogen and nitrogen to produce ammonia</u>, so:
When we <u>balance</u> the reaction we will obtain:
Now, the <u>production of nitric acid</u> with oxygen would be:
If we <u>balance</u> the reaction we will obtain:
Now, if we put the reactions together we will obtain:
We can <u>multiply</u> the second reaction by "2":
We have "" on <u>both sides</u>. In the first reaction is in the right in the second reaction is on the left. Therefore we can <u>cancel out</u> this compound and we will obtain:
On this reaction, we will have 2 nitrogen atoms on both sides, 6 hydrogen atoms on both sides, and 8 oxygen atoms on both sides. So, this would be the <u>net reaction</u> for the production of nitric acid.
Answer:
Heptane (d) > Hexane (b) 3,3 dimethyl pentane (c) > butane (a)
Explanation:
<u>The boiling points of the alkanes are depends on the following factors:</u>
- Hydrocarbons with strong intermolecular forces have high boiling points.
- Longer carbon chain molecules have high boiling points.
- Straight chain hydrocarbon molecules have high boiling points than the branched chain hydrocarbons molecules because straight chain molecule have large surface area.
The given molecules are as follows.
a) Butane
b) Hexane
c) 3,3 dimethyl pentane
d) Heptane.
The Highest to lowest boiling point order is as follows.
Heptane (d) > Hexane (b) 3,3 dimethyl pentane (c) > butane (a)
