Answer:
The correct answer is the activation energy for the reaction is lowered.
Explanation:
Enzymes are homogenous, thermolabile,biological catalyst which speed the rate of a reaction but itself remains unchanged throughout the reaction.
Enzyme basically reduces the energy barrier also called activation energy and interact with the transition state of the reaction in a complementary fashion.
Enzymes does not have any effect in the equilibrium of the reaction.
C. no difference in the electronegativity of oxygen and hydrogen
Answer: Thus the yield of uranium from 2.50 kg 
is 2.12 kg
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
To calculate the number of moles, we use the equation:
moles of 
(1kg=1000g)
As 1 mole of contains = 3 moles of U
2.97 mole of contains = 
moles of U
Mass of Uranium=
( 1kg=1000g)
Thus the yield of uranium from 2.50 kg is 2.12 kg
Answer:
Here you go I hope it helped you! :) good luck!
Answer:
10
Explanation:
the capacity for each shell for the first 20 elements can be given by
2.8.8.2
2 electrons in the first shell
8 in the 2nd and in the 3rd
and 2 in the 4th
so if both the first and 2nd shells are full,
2+8=10 electrons
