Chemistry

Answer:

Y=50.9\%

Explanation:

Hello,

In this case, given the reaction, we can directly compute the theoretically yielded grams of carbon dioxide, considering the 2:2 molar ratio between carbon monoxide (molar mass = 28 g/mol) and carbon dioxide (molar mass = 44 g/mol) and the initial reacting grams of carbon monoxide in excess oxygen:

m_{CO_2}^{theoretical}=10gCO*\frac{1molCO}{28gCO}*\frac{2molCO_2}{2molCO}*\frac{44gCO_2}{1molCO_2}   =15.7gCO_2

Thus, as only 8 g were actually yielded, we compute the percent yield:

Y=\frac{8g}{15.7g}*100\% \\\\Y=50.9\%

Best regards.

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.
