The statement that best describes the type of bond a molecule of water has and how the electrons behave is : O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it; option D

<h3>What are covalent molecules</h3>

Covalent molecules are molecules which are formed by the sharing of electrons between atoms of two or more elements whose elecyronegativity values are close to each other.

Covalent bonds are usually formed by non-metals such as hydrogen, oxygen, nitrogen to form their gases.

Example of covalent molecules include water and hydrogen gas.

<h3>What are Polar molecules</h3>

Polar molecules are molecules which are formed by the uneven sharing of electrons between atoms or by the formation of ions by substances such that the two ends of the molecule will have different charges, positive and negative.

In polar covalent molecules, the more electronegatibe element pulls the shared electrons more to itself. For example, in a water molecule which is polar, oxygen pulls the shared electrons with hydrogen more to itself to have a partial negative charge while the hydrogen atom has a partial positive charge.

Therefore, statement that best describes the type of bond a molecule of water has and how the electrons behave is : O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it; option D

Answer:

see below

Explanation:

1. One atom pulls an electron from another atom.

2. Forming bonds releases energy and is exothermic.

3. Additional bonds require more energy to break, so the bond energy is higher.

4. −153

5. O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it.

A solution is made by mixing 34.5 g of sugar with 75.0 g of water. What is the mass percent of sugar in this solution?
lubasha [3.4K]

the mass percent of sugar in this solution is 46%.

Answer:

Solution given:

mass of solute=34.5g

mass of solvent=75g

mass percent=\frac{mass\:of\:solute}{mass\:of \:solvent}*100\%

=\bold{\frac{34.5}{75.0}*100\%=46\%}

Why krypton and noble gas are not used in airships using the periodic table?
WITCHER [35]

Answer:

Since the noble gases are unreactive or inert, they are safe to use. Helium is used to fill balloons and airships, because it is much lighter that air and it will not catch fire. Neon is used in advertising signs. It will give red glow, but the color can be changes by mixing it with other gases.
