The answer is Two (B).
Tems11 [23]3 years ago

solution:

answer is two

explanation:

In sharing of electrons in the equation water each carbon atom and hydrogen atom share its one electron from its outermost orbit.

since carbon has seven electrons in its outermost orbit and it wants to get one electron to complete its octet.

while hydrogen atoms has one electron to its outermost orbit and it needs one electron to complete its duet.

similarly

second hydrogen atom do as the shame process as it also share one electron to carbon to complete its duet.

after the sharing of electrons both the atoms form molecule water which is stable.

Can someone help me please?<br> Why can’t you see individual atoms without special tools?
natta225 [31]

Answer:

Even the most powerful light-focusing microscopes can't visualise single atoms. What makes an object visible is the way it deflects visible light waves. Atoms are so much smaller than the wavelength of visible light that the two don't really interact. To put it another way, atoms are invisible to light itself.

Why is it necessary for the spins of two electrons that occupy one orbital, to be in the opposite directions? What is that law c
Mars2501 [29]

Answer:

Since electrons cannot have the same set of quantum numbers, a maximum of two can be in the n = 1 level, and a third electron must reside in the higher-energy n = 2 level. If there are two electrons in the n = 1 level, their spins must be in opposite directions.

Which of the following is not the same as 12.5 millimeters? 0.0000125 km 0.00125 hm 0.0125 m 1.25 cm
erma4kov [3.2K]
1 mm (millimeter) = 0.000001 km (kilometer)
12.5 mm = <span>0.0000125 km

1 mm = </span><span>0.00001 hm (hectometer)
12.5 mm = </span><span>0.000125 hm

1 mm = </span>0.001 m (meter)
12.5 mm = 0.0125 m

1 mm = 0.1 cm (centimeter)
12.5 mm = 1.25 cm

So the only one of the answer choices that doesn't equal 12.5 mm is 0.00125 hm, since 12.5 mm is <span>0.000125 hm.

Answer:
</span><span>0.00125 hm

Hope this helps!</span>

The side chain (R group) of the amino acid serine is CH₂OH. The side chain of the amino acid leucine is CH₂CH(CH₃)₂. Where would
Crazy boy [7]

Answer:

The answer is B, Alanine would be in the interior and serine would be on the exterior of the globular protein.

Explanation:

To further explain, the nature of solubility of side chain determines the position of the amino acid in the globular protein.

The hydrophilic amino acid such as serine are on the outside of the globular protein while the hydrophic amino acids such as leucine and alanine are on the interior of the globular protein.

This is why Alanine would be in the interior and serine would be on the exterior of the globular protein.

Cheers!
