Chemistry

An enzyme can affect a chemical reaction by bringing the reactant closer together - chemical bonds may be weakened, and reactions will happen faster than without a catalyst. The energy can also be lowered, which means reactions will proceed at a lower temperature, light presence, etc.

What are the benefit of understanding physical properties?
klasskru [66]
Physical properties help identifying a substance and how it changes.
For example: if a substance crushes easily that means it has a low density, but if it’s hard and doesn’t crush easily, that means it has a strong high density.
And eventually the substance would not end up forming a new substance.
Look at the picture below to understand more about physical changes.

A book is pushed off the edge of a table. At what point during the fall will the potential and kinetic energy be equal?
vfiekz [6]

Answer:

KE = PE at half the table Height:

Explanation

AT ANY POINT IN THE BOOK'S FALL,

TOTAL E = PE +KE

THE TOTAL E IS CONSTANT

Before the book is pushed off, the total energy is potential

TOT E=PE =MGH

BEFORE THE BOOK HITS THE GROUND, THE TOTAL E IS KINETIC

TOT=KE = MVXV/2

WHEN KE = PE

KE+PE =<u> MGH (STARTING ENERGY SINCE E IS CONSERVED)</u>

<u>OR PE+ PE = MGH</u>

<u>OR MGH' + MGH' =MGH</u>

<u>OR 2H' =</u>H

H' (NEW HEIGHT) =H/2
