Answer:
1. Ions are either negatively or positively charged species in which the number of electrons and protons are not equal.
2. The chemical bond that arises due to the sharing of electrons is termed a covalent bond.

Answer:
6L
Explanation:
<em>if it's 3L per 200kPa</em>
then it would be;
4L per 300kPa
5L per 400kPa
6L per 500kPa
that's how i'd work it out in my head, hope it helps, but not sure though!
Answer:
You multiply the 3 numbers together to get your volume, in this case it would be 4058.488 cm^3 (cm cubed)
so
V: 4058.488cm^3 ( round up to 4058.5 for convenience)
M: 27579
D: ?
So we divide mass by the volume to get density, which is
27579 / 4058.5 = ~6.79536 (can round up to 7 or 6.8)
This graph can help a lot, so maybe try and memorize it, hope I helped.
