What volume of a 0.33-M C12H22O11 solution can be diluted to prepare 25 mL of a solution with a concentration of 0.025 M?
Vsevolod [243]

The dilution formula can be used to find the volume needed

c1v1 = c2v2

Where c1 is concentration and v1 is volume of the concentrated solution

And c2 is concentration and v2 is volume of the diluted solution to be prepared

c1 - 0.33 M

c2 - 0.025 M

v2 - 25 mL

Substituting these values in the equation

0.33 M x v1 = 0.025 M x 25 mL

v1 = 1.89 mL

Therefore 1.89 mL of the 0.33 M solution needs to be diluted up to 25 mL to make a 0.025 M solution

The hydrogens and oxygen of a water molecule are held together by ______ bonds. select all that apply.
zavuch27 [327]

The hydrogens and oxygen of a water molecule are held together by covalent bonds.

<h3>What are covalent bonds?</h3>

A covalent bond is an electron exchange that causes the production of electron pairs between atoms. Covalent bonding is a stable equilibrium of the attractive and repulsive forces between two atoms that occurs when they share electrons.

Bonding pairs or sharing pairs are other names for these electron pairs. Because electrons are shared among several molecules, each atom can reach the equivalent of a full valence shell, resulting in a stable electronic state.

In organic chemistry, covalent bonds are much more common than ionic bonds. Covalent bonds unite the atoms in a single water molecule, whereas hydrogen bonds join two water molecules. Water develops a covalent bond when oxygen shares an electron with each hydrogen atom.

What kind of product is formed when a ketone reacts with a grignard reagent followed by protonation?
svet-max [94.6K]

c. a tertiary alcohol; when a ketone reacts with a grignard reagent followed by protonation a tertiary alcohol is formed.

More about tertiary alcohol:

No hydrogen atoms are bonded to the functional group's carbon in a tertiary alcohol. Alcohols that have a hydroxyl group bonded to the carbon atom and are linked to three alkyl groups are referred to as tertiary alcohols. These alcohols' structural makeup largely determines their physical characteristics.

This -OH group's existence enables alcohols to create hydrogen bonds with the atoms next to them. Because of this weak connection, alcohols have higher boiling points than their alkane counterparts.

The alcohol is referred to as a tertiary (3°) alcohol if the carbon atom carrying the alcohol group is connected to three other carbon atoms in the alcohol molecule.
