.What is the effective number of bonds between the sulfur atom and each oxygen atom in the sulfate ion
Rzqust [24]

Answer:

The effective number of bonds in sulfate ion is 1.5

Explanation:

The number of chemical bonds between two atoms is known as the bond order.

In covalent bonds between two atoms, a single bond has a bond order of one, a double bond has a bond order of two, a triple bond has a bond order of three.

If there are more than two atoms in a molecule, the effective number of bonds can be determined by applying the following steps:

1. Draw the Lewis structure.

2. Count the total number of bonds.

3. Count the number of bond groups between individual atoms.

4. Divide the number of bonds between atoms by the total number of bond groups in the molecule.

For the sulfate ion, the resonance structure is shown in the attachment below. From the structure;

Total number of bonds = (2 × 2) + (2 × 1) = 6

Total number of bond groups = 4

Effective number of bonds = 6/4 = 1.5

Therefore, the effective number of bonds in sulfate ion is 1.5

The density of iron is 7.8 g/cm^3 (cubed), what is the mass of 5 cm^3 (cubed) of it? Include the symbol for the correct unit.
Monica [59]

Answer:

<h2>The answer is 39 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of iron = 5 cm³

density = 7.8 g/cm³

It's mass is

mass = 5 × 7.8

We have the final answer as

<h3>39 g</h3>

How do you calculate the number of neutrons???? please help
vladimir1956 [14]

Answer:

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
