Part C
IrinaVladis [17]

Answer:

                     (i) 1 moles of C

                     (ii) 4.5 moles of C

Explanation:

                   The Chemical equation is as follow,

                                             A + 2 B  →  C

This chemical equation can be translated as;

(i) 1 mole of A reacts with 2 moles of B

(ii) 1 mole of A produces 1 mole of C

(iii) 2 moles of B reacts with 1 mole of A

(iv) 2 moles of B produces 1 mole of C

(v) 1 mole of C is produced by 1 mole of A and 2 moles of B

Therefore to find the number of moles of C produced by 2 mole of B we will do following proportional method.

As,

                        2 moles of B produced  =  1 mole of C

So,

                    2 moles of B will produce  =  X moles of C

Solving for X,

                      X =  2 moles × 1 mole / 2 moles

                      X =  1 moles of C

Note:

         In above problem the given moles were the same as that present in balance equation so incase if the moles are different from that of the equation then the method shown above can be used to solve it.

Lets try it for 9 moles of B:

As,

                        2 moles of B produced  =  1 mole of C

So,

                    9 moles of B will produce  =  X moles of C

Solving for X,

                      X =  9 moles × 1 mole / 2 moles

                      X =  4.5 moles of C

A massive toxic spill kills off half the population of photosynthetic plankton in the ocean. What would happen to the atmosphere
Rzqust [24]

Answer:

The amount of oxygen in the atmosphere would decrease.

Explanation:

If a massive toxic spill kills off half the population of photosynthetic plankton in the ocean. That would mean that only half of the original population of plankton will remain. Photosynthetic plankton consumes carbon dioxide from the atmosphere during photosynthesis to produce energy and releases oxygen.
