How many moles of butane gas, C4H10, react to produce 2.50 moles of H2O? How many moles of oxygen gas reacts? Given the balanced
viva [34]
The moles  of  butane gas  and  oxygen gas reacted  if  2.50  moles  of H2O is produced  is  calculated  as below

the  equation  for  reaction
2C4H10  +13 O2 = 8CO2 +10 H2O

the moles  of  butane (C4H10) reacted calculation

by  use  of mole ratio between  C4H10: H2O  which  is  2  : 10 the  moles of  C4H10=     2.50  x2/10 = 0.5 moles  of  C4H10  reacted

The  moles of  O2  reacted calculation

by  use of mole  ratio  between   O2 : H2O  which  is  13:10 the moles of O2

=   2.50  x 13/10=  3.25  moles of O2  reacted

Use the combined gas law to calculate the "corrected" volume of hydrogen at STP
solong [7]

Answer:

We will derive the combined gas equation from the law of Gases

Boyle's law

P∝1/V

PV=Constant

Charles law

V∝T

Avogadro's Law

V∝n

By combining these three equations we get the combined gas equation

PV=nRT

V=nRT/P

If n=1 mole

V=RT/P

By putting the value of R, T, and P in the above equation we can calculate the volume of the gas at STP.

The inhibition caused by the final end product of a reaction is called
Troyanec [42]

Answer:

Non competitive inhibition

Explanation:

Hello,

During enzymatic catalysis, the active sites could be occupied by the very same products' molecules turning out into an inhibition (the reaction starts to slow down since to active places are available for the reagents to react). Nonetheless this inhibition is not competitive as long as the product does not react due to the active sites it is occupying.

Best regards.
