Chemistry

Answer:

B) more genetic variation

B) when the organisms produce offspring

Explanation:

More genetic variation means the species is most likely to not die out whenever the environment changes. Take a group of giraffes with varying neck lengths, for example. If the height of the trees were to change, then less of them would die of starvation.

Genes are created through reproduction. During reproduction, an organism with different genes from its parents occurs, creating more genetic variation. Additionally, mutations can also occur, resulting in genes not from either parent.

What is the mass of 3.0 x x times 10^23 atoms of neon?
Sladkaya [172]

Answer:

10.09 grams

Explanation:

First you need to know the number of moles you are dealing with.

If you know that each mole has 6.022x10²³ of something (in this case of atoms), you can divide 3x10²³ atoms of neons by 6.022x10²³ to obtain the number of moles.

You have 0.5 moles of Neon, so then by the periodic table, you see that the molar mass of neon is 20.18g/mol, so by each mole you have 20.18 grams of neon. Multiply 20.18 grams by 0.5 moles and you got 10.09 grams of Neon
