Answer : The correct option is, (B) two covalent bonds

Explanation :

Ionic bond : It is defined as the bond that is formed by complete transfer of electrons from one atom to another atom.

That means, the atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom.

The ionic bond is usually formed between a metal and a non-metal.

Covalent bond : It is defined as the bond which is formed when sharing of electrons takes place between the atoms.

This is usually formed between two non-metals.

Metallic bond : It is defined as the bond that is formed from the electrostatic attraction between the free electrons and positively charged metal ions.

As per question, the two chemical bonds unite three atoms into a molecule, it is formed by the covalent bond.

For example : $H_2O$ is formed by the combination of 2 hydrogen and 1 oxygen atom by the two covalent bonds because hydrogen and oxygen is a non-metal element.

Hence, the correct option is, (B) two covalent bonds

One mole of silver has a mass of 107.9 grams. Approximately how many atoms of silver are present in one mole of silver?

irga5000 [103]

Answer:

The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.

Option C is correct.

Explanation:

Step 1: Data given

Mass of 1 mole silver = 107.9 grams

Step 2: Calculate the number of atoms in 1 mole of silver

To calculate the number of atoms in 1 mole, we multiply the number of Avogadro by the number of moles

Number of atoms = 1 mol * 6.022 *10^23 atoms/ mol

Number of atoms = 6.022 * 10^23 atoms

Since the number of Avogadro says there are 6.022 * 10^23 atoms per 1 mole. The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.

Option C is correct.

How many carbon dioxide (CO2) molecules are produced during the decomposition of 1.25 moles of Carbonic acid (H2CO3)? ****Rememb

Andreas93 [3]

Answer:

7.53×10²³ molecules

Explanation:

Given data:

Number of moles of carbonic acid = 1.25 mol

Number of molecules of CO₂ produced = ?

Solution:

Chemical equation:

H₂CO₃ → CO₂ + H₂O

Now we will compare the number of moles of carbonic acid with CO₂ from balanced chemical equation.

H₂CO₃ : CO₂

1 : 1

1.25 : 1.25

Number of molecules can be determine by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

Number of molecules:

1 mole = 6.022 × 10²³ molecules

1.25 mol × 6.022 × 10²³ molecules / 1 mol

7.53×10²³ molecules

If 9.0g of water contain 1.0 g of hydrogen what mass of oxygen is contained in 36 g of water

Mazyrski [523]

9/1 ratio so 9:1=36:x
X is your hydrogen in the 36g sample. To find the mass of Oxygen you subtract the mass of hydrogen from the total.
4 grams H
36-4=32 g h2o

What did rutherfords gold foil experiment help him conclude

Naya [18.7K]

It allowed him to realize that the mass of an atom is concentrated at its center because the atoms mostly went through the foil but some were deflected. He also realized that an atom probably wasn't just empty space and scattered electron and it had a positive center.

CH2 - CH2 - CH3<br> |<br> CH3 - CH2 - CH - CH2 - CH = CH2

lianna [129]

The name of that product is 1-nonene.

The sufix ene is because it is an alkene, which comes from the fact that it has a double bond.

The prefix none is because it has 9 carbon.

And the use of number 1 is because the double bond is in the carbon number 1.
