As a result of the transfer of an electron from a less electronegative atom to a more electronegative atom,

Viktor [21]

<u>Answer:</u> The correct answer is Option d.

<u>Explanation:</u>

Electronegativity is defined as the tendency of an element to attract the shared pair of electron towards itself in a compound.

When electron is transferred from less electronegative atom to more electronegative atom.

The atom which is more electronegative gains electron and undergoes reduction reaction.

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

During the transfer of electrons, energy is released when an electron looses is potential energy during the transfer.

Hence, the correct answer is Option d.

What is the molecular formula of a compound with the empirical formula so and molecular weight 96.13?

garik1379 [7]

<h3>Answer:</h3>

Molecular Formula = S₂O₂ (Disulfur Dioxide)

<h3>Solution:</h3>

Molecular formula is calculated by using following formula,

Molecular Formula = n × Empirical Formula ---- (1)

Also, n is given as,

n = Molecular Weight / Empirical Formula Weight

Molecular Weight = 96.13 g.mol⁻¹

Empirical Formula Weight = 32.06 (S) + 16.0 (O) = 48.06 g.mol⁻¹

So,

n = 96.13 g.mol⁻¹ ÷ 48.06 g.mol⁻¹

n = 2.0002 ≈ 2

Putting Empirical Formula and value of "n" in equation 1,

Molecular Formula = 2 × SO

Molecular Formula = S₂O₂ (Disulfur Dioxide)

Answer:

Hi Lovelys!!

Answer down below!!

Explanation:

Answer: Plants need water for photosynthesis in order to make food. Water is needed more for cooling, to maintain body temperature and transport nutrients.

Reason: Plants need water for photosynthesis. Water also helps move nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop. Too much water can cause a plant's roots to rot. Plants are about 80-95% water and need water for multiple reasons as they grow including for photosynthesis, for cooling, and to transport minerals and nutrients from the soil and into the plant.

Hope this helps!! =3

Have a wonderful day, evening, or night!!

Is food a fuel? Explain your answer. a ?

diamong [38]

Answer:

no, food is not a fuel because it just give energy to do many activities but it will not provide any fuel only the dead and decaying material which berries under the soil then after a long years it becomes fossil fuel
