Question

A)
The energy change within a system is based on the change in the bond energies of which parts of achemical reaction?
(1 point)
the reactants only
the products only
neither the products nor the reactants
both the products and reactants

A)
Which list best describes molecules that will react?
(1 point)
hotter, moving quickly, lower energy
cooler, moving quickly, higher energy
hotter, moving quickly, higher energy
cooler, moving slowly, lower energy
A)
When plants perform photosynthesis, they absorb the sun’s energy and use it to convert water andcarbon dioxide into oxygen and the energy-rich sugar, glucose. The following reaction occurs:
6H
O + 6CO
→ 6O
+ C
H
O
In this reaction, does it take more energy to break up the reactants, or is more energy released whenforming the bonds of the products?

More energy is absorbed when breaking up the reactants because they need to form energy-rich productsand need energy applied to do so.
More energy is absorbed when breaking up the reactants because energy from the sun is applied to breakthe bonds.
More energy is released when forming the bonds of the products because energy is stored in glucose, anenergy-rich sugar.
More energy is released when forming the bonds of the products because the molecules broken up aresimple, but the molecules formed are complex.

Answer 1

1) both the products and reactants

2) hotter, moving quickly, higher energy

3) More energy is absorbed when breaking up the reactants because energy from the sun is applied to break the bonds.
