What is the valency & molecular formula of sulphate?

Answers

Explanation:

Let's consider sulphate radical, the chemical formula is given by SO42−. Here we can see there is a -2 charge on SO4, which means it has -2 valency. Now look at the option (a), phosphate can be written as PO43−. There is -3 charge on PO4, that means it has -3 valency.

Explanation:

molecular formula of sulphate ion is SO₄²⁻

and

the valency of sulphate ion is 2.

Identify the atom oxidized, the atom reduced, the oxidizing agent, and the reducing agent. 2Fe + 3V2O3 -------> Fe2O3 + 6VO

Answers

In the given reaction, Fe is the reducing agent and V is the oxidizing agent.

What is a reducing agent?

An atom or compound that loses its electrons to other substances in a reduction-oxidation reaction and gets oxidized to a higher valency state is called a reducing agent.

A reducing agent can be defined as one of the reactants of a redox reaction that reduces the other reactant by giving its electrons to the reactant. If the reducing agent can not give away its electrons to others in a reaction, then the reduction reaction cannot occur.

Given, the following chemical reaction:

2Fe + 3V₂O₃ → Fe₂O₃ + 6VO

The V₂O₃ oxidation state of V:

2 x + 3(-2) = 0

2x = 6

x = + 3

The Fe₂O₃ oxidation state of Fe:

2 y + 3 (-2) = 0

2y = 6

y = + 3

The V acts as an oxidizing agent because it accepts one electron to change the oxidation state from +3 to +2.

Fe acts as a reducing agent because it gives out its electrons to change the oxidation state from 0 to +3.

Answers

A triangular shaped body of water that forms where a stream in to the larger body of water is a delta.

Please take thetime to rate, pick the Brainliest answer (not necessarily mine!), and thank me if you feel Ihelped with this question! Thank you, it helps me a lot. :)

This triangular body of water is called a delta. It is shaped like the Greek letter delta and was coined by Herodotus, the father of history who lived from 484 to 425 BC by seeing the deltoid shape at the mouth of the Nile.

Deltas occur throughout the world except at the poles. They all have three things in common, namely:

1. The presence of a large catchment basin. The top 30 river deltas all have catchment basins.

2. They all are at the mouth of large river systems that carry large quantities of clastic sediments (soils or portions of rocks that have been moved by water from where they formed)

3. They are not found near geologically active coastlines. They take a long time to develop so they are very rarely situated on tectonically active coast.

Answers

A meteorologist predicts fog in the morning over lakes and river bottoms because of the atmospheric conditions and their interactions with the hydrosphere. The hydrosphere is the region on the Earth's surface where the total water on the planet is found. The hydrosphere can be in the form of liquid, vapor, or ice.
