Is the H¬O bond in water nonpolar covalent, polar covalent, or ionic? Define each term, and explain your choice.
nydimaria [60]

Like hydrogen fluoride (HF), water (H2O) is a polar covalent molecule.

The electron pair in a non-polar covalent bond is shared equally by the two bonded atoms, but in a polar covalent bond, the electron pair is shared unequally by the two bonded atoms. Differences in electronegativity are what lead to polar bonding.

The entire transfer of valence electron(s) between atoms is referred to as an ionic bond. It is a kind of chemical connection that produces two ions with opposing charges. In ionic bonding, the nonmetal takes the lost electrons to form a negatively charged anion while the metal loses them to become a positively charged cation.

Glucose (c6h12o6) has a single carbonyl group (-c=o) in its linear form. based on the number of oxygen atoms in glucose, how man
sveta [45]
Glucose is a hexose monosaccharide. It is one of the three major monosaccharides along with fructose and galactose. These are carbohydrates with a general formula of Cₓ(H₂O)ₓ, where x could be any number.

Now, you don't have to know the structural formula of the glucose to answer this. Just account all the elements in the glucose. You know that there are 6 oxygen atoms all in all. One of them belongs to the single carbonyl group. Consequently, that would mean that the remaining 5 oxygen atoms bond with hydrogen atoms to form 5 OH groups.

Just to be sure let us refer to the structural formula of glucose shown in the picture. It indeed has 5 OH groups.

How many liters of water do we need to add to 5.00 moles to get a 0.648 M solution?
Tanya [424]

Answer: This is a typical acid/base equilibrium problem, that involves the use of logarithms.

Explanation:We assume that both nitric acid and hydrochloric acid dissociate to give stoichiometric

Moles of nitric acid:

And, moles of hydrochloric acid:

This molar quantity is diluted to

Now we know that water undergoes autoprotolysis:

Alternatively, we know further that
