Answer:
A. Physical science is the study of energy and inanimate matter. Life science is the study of living organisms.
Explanation:
Sciences can be grouped into physical science and life sciences. PHYSICAL SCIENCE is a branch of science that involves the study of energy and inanimate objects i.e lifeless. Physical science encompass the following: physics, chemistry, astronomy, geology etc.
On the other hand, LIFE SCIENCES, as the name implies, is the study of living organisms. It is also referred collectively to as BIOLOGICAL SCIENCES and it includes aspects such as biology, botany (plant), zoology (animal), microbiology (microbes), biochemistry etc.
Answer:
5.2g copper (Cu) => 0.082 moles copper (2 sig.figs.)
Explanation:
mole conversions:
grams to moles => divide by formula wt.
moles to grams => multiply by formula wt.
gas volumes to moles => divide volume by 22.4Liters/mole (STP conditions only)
This problem:
mass to moles => divide by formula wt.
mass = 5.2g = 5.2g/63.5g/mole = 0.082 moles copper (2 sig.figs.)
Answer:
The enthalpy of reaction for the reaction of chlorine with ozone is -162.5 kJ.
Explanation:
..[1]
..[2]
..[3]
The enthalpy of reaction for the reaction of chlorine with ozone can be calculated by using Hess's law:
[2] - [1] = [3]
The enthalpy of reaction for the reaction of chlorine with ozone is -162.5 kJ.
Answer:
D
Explanation:
I think it is D. Think about it- if a human jumps, they are less than the gravitational force. But, if you are greater than the gravitational force, I think you will go into space.
