1. How many moles of CO2 can be produced from a reaction of 10.0 moles CzHg?

mr_godi [17]

Answer:

$20$ moles of CO2 can be produced from a reaction of 10.0 moles C2H6

Explanation:

In this reaction -

2 moles of C₂H6 produces four molecules of Carbon dioxide (CO2)

So 1 mole of C₂H6 will produce $\frac{4}{2} = 2$ moles of Carbon dioxide (CO2)

Thus, 10 moles of C₂H6 will produce $2 * 10 = 20$ moles of Carbon dioxide (CO2)

Neha and Reha are playing see-saw. Neha is sitting 60 cm away from the fulcrum and Reha is sitting 40 cm away from the fulcrum.

stich3 [128]

Answer:

Reha should apply 540 N to lift Neha.

Explanation:

L = 360 N

LD = 60 m

E =?

ED = 40m

NOW

L * LD = E * ED

360 *60 = E*40

21600/40 = E

540 N = E
