Tanzania [10]

Answer:Yes,enzymes are catalyzed reactions

Explanation:Enzymes are protein that speeds up chemical reactions. Enzyme catalyzed reaction are divided into two:

Homogeneous reaction

Heterogeneous reaction.

Homogeneous catalysts occupy the same phase as the reaction mixture, while heterogeneous catalysts occupy a different phase.

Acid catalysis, organometallic catalysis, and enzymatic catalysis are examples of homogeneous catalysis.

Would the molecules in a gas have more or less movement than the molecules in a solid ? PLEASE HELP WILL MARK BRAINLY
Sergeeva-Olga [200]

Molecules in a gas will have more movement than molecules in a solid. This is because the molecules in solid matter are packed very tightly together to maintain its shape, whereas with gases they are spaced much further apart and fairly free to move. Hope this helps!

How many joules of heat are absorbed to raise the temperature of 435 grams of water at 1 atm from 25°C to its boiling point, 100
zepelin [54]
The energy absorbed may be calculated using:
Q = mcΔT
Where Q is the energy absorbed, m is the mass of water, c is the specific heat capacity of the water and ΔT is the change is the temperature of the water. Substituting the values,
Q = (435)(4.18)(100-25)
Q = 136,372 J

The energy absorbed is 136.4 kJ
