Answer:

K = 2.96x10⁻¹⁰

Explanation:

Based on the initial reaction:

N2O4 ⇄ 2NO2; K = 1.5x10³

Using Hess's law, we can multiply this reaction changing K:

3 times this reaction:

3N2O4 ⇄ 6NO2; K = (1.5x10³)³ =3.375x10⁹

The inverse reaction has a K of:

6NO2 ⇄ 3N2O4 K = 1/3.375x10⁹;

<h3>K = 2.96x10⁻¹⁰</h3>

Describe a consequence of overpopulation of deer in the forest areas of the northeastern United States
muminat
If the deer population were to overpopulate then that would mean that there would not be enough room for other living things. Also, there would be less grass and plants because of the deer eating it all. Hope this helps!!!

Ethanol (C2H5OH) is produced from the fermentation of sucrose in the presence of enzymes.
madam [21]

actual yield of ethanol = 305.0g

molar mass of sucrose = 342g

molar mass of ethanol  =46g

mass of sucrose = 665g

mole of sucrose = mass / molar mass = 665/342

mole of sucrose =1.9 mole

sucrose :  C2H5OH

       1      :  4

     1.9     : 1.9x4 =7.6 mole of C2H5OH are formed

mass (therotical yield ) of C2H5OH= mole x mass

mass (therotical yield ) of C2H5OH= 7.6 x 46 = 349.6g

percent yields of ethanol =  actual /therotical x100

=305/349.6x100 = 87.24 %

What are Newton's three laws of motion? Are they correct?​
muminat

Answer:

Explanation:

Of course Newton's three laws of motion are correct, because they were verified several hundred of years ago and they continue working today, for such systems. Science is accumulative. What modern physics has done is to constraint the range of validity of those laws.

Newtons first law of motion states that everybody continues in it rest or of uniform motion in a straight line unless an external force is applied on it.

Newtons second law of motion states that acceleration produced on a body by a force is directly proportional to the applied force and inversely proportional to the mass of body.

Newtons third law of motion states that to every action there is equal and opposite reaction.

Hope it will be helpful :)
