The answer is (1) CaCO3. The bond between C and O is covalent bond. And the bond between Ca2+ and CO3 2- ion is the ionic bond. So the compound CaCO3 satisfy this condition.

Answer: The correct answer is option (A).

Explanation:

Covalent bonds are those bonds in which sharing of an electrons is present in between the two atoms. Generally this type of bonding is found when electro-negativity difference between is very less or zero.

Ionic bonds are those bonds in which complete transfer of an electrons from one atom to another atom is present.Generally this type of bonding is found when electro-negativity difference between two atoms is very large.

Compound CaCO_3 contains both ionic and covalent bonds.

  • Bond between carbon and oxygen atoms in carbonate ion is a covalent bond. Being a ploy-atomic ion it carries 2- charge.
  • Calcium ion being 2+ charge will form ionic bond with carbonate ion.

What is the suffix for -<br>✯ Alcohols<br>✯ Ketones<br>✯ Halogens<br><br>thankyou ~​
antoniya [11.8K]

Answer:

ane, al, keto

ol, al, keto

ol, al, one

ol, ane, one.

Explanation:

The suffix –ol is used in organic chemistry principally to form names of organic compounds containing the hydroxyl (–OH) group, mainly alcohols (also phenol). The suffix was extracted from the word alcohol. The suffix also appears in some trivial names with reference to oils (from Latin oleum, oil).

Functional group is a ketone, therefore suffix = -one

Hydrocarbon structure is an alkane therefore -ane

The longest continuous chain is C5 therefore root = pent

The first point of difference rule requires numbering from the left as drawn to make the ketone group locant 2-

pentan-2-one or 2-pentanone

CH3CH2CH2C(=O)CH3

Describe the main difference between the Bohr model and the electron cloud model of the atom
Leno4ka [110]

Answer:

The main difference between the two models is <em>the position of the electron in the atom</em>.

Explanation:

  • <em>Bohr model:</em> The electrons are moved around the nucleus in circular definite paths (orbitals or shells). Also, he could not find or detect the exact position of electron.
  • <em>Electron cloud model:</em> It is supposed by  Erwin Schrodinger. He showed that the emission spectra of the atom is the way to detect the probability of electron position.

What happens when a catalyst is used in a reaction?.
den301095 [7]
A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without being used up in the reaction. After the reaction occurs, a catalyst returns to its original state and so catalysts can be used over and over again.
