what's the common name for hydrogen oxide​

Answer:

Ionic bond and covalent bond

Explanation:

The two main types of chemical bonding are ionic bond and covalent bond.

In an ionic bond, there is a transfer of electrons from one atom to another. Usually from a metal to a nonmetal leading to the existence of an ion pair. Ionic compounds are soluble in water and have high melting and boiling points due to the strong electrostatic interaction between ions in the compound.

A covalent bond involves sharing of electrons between atoms. In an ordinary covalent bond, the shared electrons are furnished by the two bonding atoms while in a dative covalent bond, the two bonding electrons are furnished by only one of the bonding species.

The given molecule is an aldehyde with the formula HCHO. It is the simplest and primary aldehyde . Hence, option c is correct.

Aldehydes are a class of organic compounds that contain a carbonyl group (a carbon double-bonded to an oxygen) at the end of a carbon chain. The general formula for an aldehyde is RCHO, where R is a substituent or side chain attached to the carbonyl group.

Aldehydes are often characterized by their distinctive odor, which can be described as pungent and irritating. Some common aldehydes include formaldehyde (used in building materials and as a disinfectant), acetaldehyde (found in alcoholic beverages), and benzaldehyde (used in food flavorings).

Aldehydes are important intermediates in many chemical reactions, and they are used in a variety of industrial and laboratory applications. They can be synthesized by the oxidation of primary alcohols or by the partial oxidation of hydrocarbons. The given compound is formaldehyde HCHO.

8.72 × 10^5 moles

Explanation:

To find the number of moles in 5.25 x 10^29 molecules of sucrose, we divide the number of molecules by Avagadro constant (6.02 × 10²³ molecules). That is;

no. of moles = no. of molecules ÷ 6.02 × 10²³ molecules

In this case of sucrose, no of moles contained is as follows;

5.25 × 10^29 ÷ 6.02 × 10²³

5.25/6.02 × 10^ (29-23)

0.872 × 10^6

D) Water is less dense as a liquid than as a solid because of changes in bond structure.

Explanation:

I hope I was able to help!

Have a nice day :)

The correct statements about water is that hydrogen bonding causes water to be strongly cohesive and is less dense as a liquid and solid.

It is bonding in between the hydrogen atom and most electronegative atoms like flourine, chlorine, oxygen atoms, etc.

Hence water is less dense as a liquid than as a solid because of changes in bond structure and hydrogen bonding causes water to be strongly cohesive.

Ghana Empire is was a kingdom in western Africa.

The Oyo Empire was the ancient African Kingdom is located in western Africa.

The Oyo Empire prospered on regional trade and became a key facilitator in moving slaves from Africa's interior to the coast and waiting European sailing ships, with its capital at Old Oyo near the River.

The human trade was so extensive that this region of Africa became known simply as the "Slave Coast."

Finally, despite all efforts, the Oyo Empire became a protectorate of the United Kingdom in 1888; its states ceased to exist as a superpower, and it never regained its prominence in the region.

During the colonial period, however, the Yoruba were one of Africa's most urbanized groups.

Thus, the ancient African kingdom of the Oyo Empire was located in western Africa.

Answer:

1.72 M

Explanation:

Molarity is the molar concentration of a solution. It can be calculated using the formula a follows:

Molarity = number of moles (n? ÷ volume (V)

According to the information provided in this question, the solution has 58.7 grams of MgCl2 in 359 ml of solution.

Using mole = mass/molar mass

Molar mass of MgCl2 = 24 + 35.5(2)

= 24 + 71

= 95g/mol

mole = 58.7g ÷ 95g/mol

mole = 0.618mol

Volume of solution = 359ml = 359/1000 = 0.359L

Molarity = 0.618mol ÷ 0.359L

Molarity = 1.72 M

Answer:

I got 1.14 mol So3 as the answer

hopefully if this could help

Answer:

Solution given:

H20=1+1+16=18grams

we have

1 mole of water =18grams

now

150grams of water=1/18*150=25/3 =8.33mole.

150 grams of water =8.33mole.

Note:

mole =given mass/actual mass of molecule/atom

1 mole of water is 18 grams.

Then,

150 grams of water,

→ 1/18 × 150

→ 25/3

→ 8.33333 . . .

Hence, 150 grams of water is 8.3 moles.

Answer:

Bonding property

Explanation:

Distillation deals with boiling solutions. Therefore the boiling point has a major part to play. Boiling point of a substance deals with the type of bonds present. For example water has hydrogen bonding which is a weak intermolecular force therefore the boiling point of water isn't that high. If we were to focus on an ionic compounds the boiling point would be higher because ionic compounds have ionic bonding which are stronger bonds which therefore requires more energy to break those bonds therefore a higher boiling point.

In this case for the ethanol to distill the property it's focusses on is the bonds. The strength of the bonds really.

If a 6.00 g sample of an optically pure compound was dissolved in 40.0 mL of [tex]CCl_4[/tex] and the observed rotation was +3.30°, measured in a 10.0 cm (1.00 dm) polarimeter tube, how would one determine the specific rotation of the pure compound?

Answer: The specific rotation of the pure compound is [tex]+22^o[/tex]

Explanation:

To calculate the specific rotation of a pure compound, we use the equation:

[tex][\alpha]=\frac{\alpha_{\text{observed}}}{C\times l\text{( in dm)}}[/tex]

where,

[tex][\alpha][/tex] = specific rotation of a pure compound

[tex]\alpha_{\text{observed}}[/tex] = observed rotation of the compound = [ex]+3.30^o[/tex]

C = concentration in g/mL = 6.00 g/40 mL = 0.15 g/mL

l = path length = 1.00 dm

Putting values in above equation, we get:

[tex][\alpha]=\frac{+3.30^o}{0.15\times 1.0}[/tex]

[tex][\alpha]=+22^o[/tex]

Hence, the specific rotation of the pure compound is [tex]+22^o[/tex]

Answer:

Explanation:

The phosphate group PO4 is bonded covalently (bond between two non metals). While the sodium being bonded to the phosphorus atom is an ionic bond (bond between a metal and a non metal)

The chemical bonding in sodium phosphate, Na3PO4 is classified as both covalent and ionic. Therefore, option C is correct.

An enduring attraction between atoms or ions known as a chemical bond is what allows molecules and crystals to form. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds.

Chemical bonds are formed when the atoms in a compound's molecule are brought together and kept together by a powerful combining force. Ionic and covalent bonds are the two different types of chemical bonds.

Molecules are held together by chemical bonds, which also make transient connections necessary for life. chemical bonds, including as ionic, covalent, and hydrogen bonds, as well as London dispersion forces.
