The ratio between C and SO2 is 5:2 So....
take 5.52 * 5 / 2 = 13.8 mol C needed

Answer : The moles of carbon needed will be, 13.8 moles

Explanation : Given,

Moles of SO_2 = 5.52 mole

Now we have to calculate to moles of carbon.

The given balanced chemical reaction is,

5C(s)+2SO_2(g)\rightarrow CS_2(l)+4CO(g)

From the balanced chemical reaction, we conclude that

As, 2 mole of SO_2 react to give 5 moles of carbon

So, 5.52 mole of SO_2 react to give \frac{5}{2}\times 5.52=13.8 moles of carbon

Therefore, the moles of carbon needed will be, 13.8 moles

Entropy of a system decreases with decrease in Temperature T/F
Svet_ta [14]

Answer: The given statement is true.

Explanation:

Entropy means the measure of randomness present in a substance. That is, an increase in temperature will lead cause more motion in the particles of a substance more will be their kinetic energy.

As a result, there will occur more collisions due to which randomness of molecules will increase. Hence, there will be increase in entropy.

So, when we decrease the temperature then there will be decrease in motion of particles. As a result, lesser number of collisions will take place between them. Hence, degree of randomness will also decrease.

Thus, we can conclude the statement entropy of a system decreases with decrease in temperature, is true.

If the density of water is 1g/cm3 what is its specific gravity
MakcuM [25]

Answer:

Specific gravity is the density of asubstance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density(but without any units).
