<h3><u>Answer;</u></h3>

<em>ZnS(s) + 2O2(g) → ZnSO4(s) </em>

<h3><u>Explanation;</u></h3>
  • <em><u>Oxidation </u></em>involves the loss of electrons while<em><u> reduction </u></em>is the gaining of electrons. Oxidation-reduction reaction is a reaction which involves the gaining of electrons and loss of electrons.
  • Oxidation may also be referred to as <em><u>increase in the oxidation state </u></em>of an atom while reduction is <u><em>the decrease of oxidation state</em></u> of an atom.
  • The reaction<em> ZnS(s) + 2O2(g) → ZnSO4(s) </em>is an example of a redox reaction or what we call oxidation-reduction reaction.
  • The <u><em>oxidation number of sulfur in ZnS is -2, while the oxidation number of sulfur in ZnSO₄ is 4</em></u>. This means<em><u> sulfur has undergone oxidation.</u></em>
  • The <em><u>oxidation number of oxygen in oxygen gas is Zero, and its oxidation number in ZnSO₄ is -2,</u></em> therefore <em><u>oxygen has undergone reduction.</u></em>

Actually Welcome to the concept of Efficiency.

Here we can see that, the Input work is given as 2.2 x 10^7 J and the efficiency is given as 22%

The efficiency is => 22% => 22/100.

so we get as,

E = W(output) /W(input)

hence, W(output) = E x W(input)

so we get as,

W(output) = (22/100) x 2.2 x 10^7

=> W(output) = 0.22 x 2.2 x 10^7 => 0.484 x 10^7

hence, W(output) = 4.84 x 10^6 J

The useful work done on the mass is 4.84 x 10^6 J

Answer:

Yes

Explanation:

There are so many planets out there that there must be habitable planets if not in our galaxy but the Universe.

Although the chances of advanced life are slim, small primitive life like microbes or sea life may still exist.

A car travels 82 meters do North and 14 seconds the car turns around and travels 44 m due south in four seconds what is the magn
Yakvenalex [24]

Answer:

2.11 m/s

Explanation:

Take north to be positive and south to be negative.

Average velocity = displacement / time

v = (82 m + -44 m) / (14 s + 4 s)

v = 2.11 m/s

The velocity is positive, so it is 2.11 m/s north.  The magnitude of the velocity is 2.11 m/s.
