Which statement explains the polarity of a water molecule?

Physics
1 answer:
timofeeve [1]3 years ago
8 0

Answer:

D. The oxygen side is partially negative because electrons are pulled toward the oxygen side.

Explanation:

The water molecule is polar by the virtue of covalent bonds and the hydrogen bonds within and between its molecule.

The oxygen side is partially negative because the electrons are pulled toward the oxygen side.

Between oxygen and hydrogen that makes up the water molecule, oxygen is more electronegative.

An electronegative atom has more affinity for electrons. Since the electrons in the molecule of water is shared between hydrogen and oxygen, the more electronegative specie which is water draws the electron more to itself.

This leaves a net negative charge on the oxygen atom.

Why is the pressure so high deep inside the outer planets?
AveGali [126]

Answer:

Due to its larger size

Explanation:

This is due to those planets being much larger than Earth. The larger a planet is, the more gravity that planet has, since gravity is mainly calculated based on the mass and radius of the planet. Also since the pressure deep inside of the planet depends mainly on the gravity of that planet on the surface, this is calculated as the square of the planet's surface gravity. Ultimately, the bigger the planet is the higher the pressure deep inside the planet will be.

A juggler throws a bowling pin straight up in the air. After the pin leaves his hand and while it is in the air, which statement
yuradex [85]

Answer:

The velocity of the pin is opposite its acceleration on the way up.

Explanation:

A juggler throws a bowling pin straight up in the air. After the pin leaves his hand and while it is in the air, the velocity of the pin is opposite its acceleration on the way up.

When an object is thrown straight up in the air, the acceleration due to gravity is acting in the opposite direction. As a result, the velocity of the pin is acting in the opposite direction on the way up.

Hence, the correct option is (d).

The mass of the parts is always ___ the mass of the whole when looking at nuclear masses.
Allushta [10]
<span>When looking at nuclear masses we speak of the processes nuclear fision and nuclear fusion. </span>In fission a nucleus breaks up, into two nuclei. In fusion on the other hand two light nuclei combine to form one heavier nucleus. The relation 
E=m*c^2. explains the difference in masses. <span>
So, in case of nuclear fusion t</span><span>he mass of the parts is always </span>more than the mass of the whole when looking at nuclear masses. In case of nuclear fusion. And in case of nuclear fision, the mass of the parts is always less<span> than the mass of the whole when looking at nuclear masses. In case of nuclear fusion</span>

Solve for the indicated variable<br> mass (m):<br> 200 N = m (3.5 %)
goblinko [34]

Answer:

5714.29

Explanation:

The given expression is:

          200 = m(3.5% )

To solve this problem, we use the concept of multiplicative inverse;

   The multiplicative inverse involves using the reciprocal of 3.5% to multiply both side of the expression;

         200  = m x \frac{3.5}{100}  

           m  = \frac{100}{3.5}  x 200  = 5714.29
