Basically, the graph shows a linear (line) relationship with mass and volume. The slope will equal the density of the substance because mass/volume is the equation for density. Your paper is a bit unclear, but I can understand this much, Hope this helped a little bit :)

How many grams of NH3 can be produced from 2.93mol of N2 and excess H2?
mote1985 [20]
<span>1 mol of N2 is 28 gms, thus, 2.93mol is 84 gms.

According to the equation-

N (2 + 3H (2) =  2NH(3) 

28gms (1mol) of N2 produces 34gms of NH3

so, 84gms of N2 will produce:

28gms of N2----->34gms of NH3
84gms of N2-----> 28/84 = 34 / x

x= (34*84) / 28

Answer: 102gms</span>

Which of the following is a major difference between lactic acid and alcohol fermentation?
pishuonlain [190]

Both lactic acid and alcoholic fermentation begin with pyruvic acid and nadh. they are anaerobic processes that result in the production of energy in the absence of oxygen. So basically the two differences are that one makes ethanol and one makes lactic acid, and the other is that they are made by different species.


Alcohol fermentation requires aerobic conditions, while lactic acid fermentation requires anaerobic conditions.

HEYYY FAM IS THIS RIGHT
Otrada [13]

Answer: A reversible reaction is a reaction that takes place in back and front directions. If the reaction were to reach equilibrium, the rate of forward direction would be equal to that of the reverse reaction.

Explanation:

Reversible reactions :

These are the reaction in which reactants reacts to give product and products reacts to give reactants as a product in return.

        A+B\leftrightharpoons C+D

  • In above equation, 'A' and 'B' are reacting together to give 'C' and 'D', as products and vice-versa.
  • When the above reaction reaches equilibrium the rate of forward and backward reaction becomes equal.
