Answer:
not sure, but you know what?
Explanation:
you are amazing! keep doing what youre doing!
Explanation:
Since, it is shown that the reaction has been reversed. Therefore, value of will become .
Hence, new
=
= 20
Also, the number of moles of each reactant has been halved. So, for the reaction will also get halved.
Therefore, = =
= 4.47
As the value of is given as +39.0 kJ. So, it means that the reaction is endothermic in nature. So, energy of reactants will be more than the products. Hence, according to Le Chatelier's principle reaction will move in the forward direction.
As a result, will also increase with increase in temperature.
Explanation:
Percentage ethylene by weight = 57%
Percentage propylene by weight = 43%
Suppose in 100 grams of polymer:
Mass of ethylene = 57 g
Mass of propylene = 43 g
Moles of ethylene =
Moles of propylene =
1 mole = molecules/ atoms
Units of ethylene =
Units of propylene =
a) Fraction of ethylene units:
b ) Fraction of propylene units:
<h3><u>Answer;</u></h3>
Find the number of 1-foot cubes that fill the fish tank
<h3><u>Explanation;</u></h3>
Volume of a cuboid such as the fish tank is given by the product of length width and height;
Such that; Volume = length × width × height
Similarly, we can count the number of 1 foot cube that can fill the fish tank.
And since each cube has a volume of 1 cubic ft, then the number of cubes will be equivalent to the volume of the fish tank in cubic ft.
