Answer:

iron sulfate

Explanation:

Electrostatic attraction as bonds between ions is characteristic of the electrovalent bond or the ionic bond

In this type of bond, there is electron transfer from one atom to another. The atom that looses electrons become positively charged while the atom that gains electrons becomes negatively charged.

In iron sulfate, there is electrostatic attraction between Fe II ions and sulphate ions, making iron sulfate an ionic compound.

The answer option which is not a benefit of using biofuels instead of fossil fuels is: D. Fossil fuels may be used in the production of biofuels.

Renewable energy is also referred to as clean energy and it refers to a type of energy that is generated through natural sources or technology-based processes that are replenished constantly.

Some examples of these natural sources are:

Non-renewable energy refers to a type of energy that is generated through artificial sources and as such cannot be replenished such as coal, natural gas, fossil fuels, petroleum.

In conclusion, fossil fuels cannot be used in the production of biofuels.

Answer:The Strong Nuclear Force (also referred to as the strong force) is one of the four basic forces in nature (the others being gravity, the electromagnetic force, and the weak nuclear force). As its name implies, it is the strongest of the four. However, it also has the shortest range, meaning that particles must be extremely close before its effects are felt. Its main job is to hold together the subatomic particles of the nucleus (protons, which carry a positive charge, and neutrons, which carry no charge. These particles are collectively called nucleons). As most people learn in their science education, like charges repel (+ +, or - -), and unlike charges attract (+ -).Hope this helps

A chemical formula is like a recipe for a chemical substance.

A chemical formula lists the elements that consist the compound as well as the number of atoms of each element in the compound's smallest unit, whether a molecule or a formula unit. Cognizing the elements' names and a few basic rules allows us to name simple compounds given a chemical formula.

Chemical formulas are classed into three types: empirical, molecular, and structural.

Empirical formulas depict the simplest whole-number ratio of atoms in a compound, whereas molecular formulas depict the number of each type of atom in a molecule and structural formulas depict how the atoms in a molecule are bonded to each other.

Thus, A chemical formula is like a recipe for a chemical substance.

Answer:

There are 30 atoms in total

Explanation:

There is 5 carbon, 5 of whatever A is and 4 oxygens but since the whole symbol has been multiplied by 5 there would be 20 oxygen

So 20 + 5 + 5 = 30 atoms

C, 0.746 mol Ag.

1 mol Ag = 6.022 x 1023 atoms of Ag -> 4.49 x 1023 atoms of Ag x 1mol Ag/6.022 x 1023 atoms -> 0.746 mol Ag

The moles of Ag that contain 4.49  [tex]\rm \times\;10^2^3[/tex] atoms have been 0.745 moles.

The number of atoms in a mole can be given by the Avagadro number. The Avagadro number has been equal to the number of atoms in a mole of compounds. The Avagadro number has been constant with a value of 6.023 [tex]\rm \times\;10^2^3[/tex].  

6.023 [tex]\rm \times\;10^2^3[/tex] atoms = 1 mole

So, for the given 4.49  [tex]\rm \times\;10^2^3[/tex] atoms:

4.49  [tex]\rm \times\;10^2^3[/tex] atoms = [tex]\rm \dfrac{1}{6.023\;\times\;10^2^3}\;\times\;4.49\;\times\;10^2^3[/tex] moles

4.49  [tex]\rm \times\;10^2^3[/tex] atoms = 0.745 moles.

The moles of Ag that contain 4.49  [tex]\rm \times\;10^2^3[/tex] atoms have been 0.745 moles.
