Answer:
True
Explanation:
Because atoms with the same number of valence electrons react in similar ways with other elements.
The answer you're looking for is <u>B. Cell division.</u> Centrioles are involved in the development of spindle fibers in cell division. I hope that this answer helps you out!
I understand here "bias" to be the uncertainty of measurements. So the order will be the following:
6.4 ± 0.5 s
<span>6.6 ± 0.1 s,
</span><span>6.63 ± 0.01 s,
</span><span>6.52 ± 0.05 s,
</span>
(notice how the second number, the one behind the symbol ± gets smaller, as the bias gets smaller).
Answer:
Yes, that is correctly balanced. 2 H2 + 1 O2 = 2 H2O is already balanced.
Explanation:
If you count up the number of hydrogen atoms and oxygen atoms on each side, you will see that they are equal:
2 H2 + 1 O2 (4 hydrogen and 2 oxygen) = 2 H2O (4 hydrogen and 2 oxygen).
