Which of the following is the best explanation for a covalent bond?
Scrat [10]

Answer:

A. electrons simultaneously attracted by more than one nucleus

Explanation:

  • Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.
  • It is the bond which is generally occurs within non metals as they share electrons to complete their octet.
  • The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .

Thus, the electrons are attracted by the two different nucleus of the atoms that are taking part in the bonding.

<u>So, the correct answer is:- A. electrons simultaneously attracted by more than one nucleus</u>

"how many moles of calcium atoms are in 2.5 moles of calcium carbonate caco3"
Montano1993 [528]

Answer: -

2.5 moles of calcium atoms are in 2.5 moles of calcium carbonate CaCO₃

Explanation: -

In order to solve such types of problems, the first step would be to write the chemical formula of the compound.

The chemical formula of calcium carbonate = CaCO₃

The chemical symbol of Calcium is Ca.

From the formula of calcium carbonate we can see that

1 mole of CaCO₃ has 1 mole of Ca

2.5 mole of CaCO₃ has \frac{1 mole Ca }{1 mole CaCO₃} x 2.5 mole CaCO₃

= 2.5 mol of Ca.

∴2.5 moles of calcium atoms are in 2.5 moles of calcium carbonate CaCO₃
