Group two elements are
a. Metals b. Nonmetals c. Transition metals is c
The substance is dead or alive is determined by response or consciousness of the substance to external stimulus.
<h3><u>Explanation</u>:</h3>
The living organisms do have several characteristics. They are growth, reproduction, consciousness etc. But among them, consciousness is the only feature that's confined within only the living world. No non living things have this feature.
So if the scientist can find that the substance found have some response to external stimulus, then it does have life. And if it doesn't response to any sort of external stimulus, then it doesn't have life.
The possible options for the proposed multiplication or division of measurements are:
1. 9.0 km * 7.0 km = 63 km²; this is a correct option because km² is dimensionally correct.
3. 24 dL²/0.60 L = 0.24 L²/0.60 L = 0.4 L is a correct option since L is a unit of volume.
<h3>What are the possible options among the proposed multiplication or division of measurements?</h3>
The possible options among the proposed multiplication or division of measurements are those which are dimensionally correct.
Considering the given options:
1. 9.0 km * 7.0 km = 63 km²
This is a correct option because km² is dimensionally correct as it is a unit of area.
2. 2.0 g² * 0.043 kg is not correct since there is no unit of square mass.
3. 24 dL²/0.60 L = 0.24 L²/0.60 L = 0.4 L is a correct option since L is a unit of volume.
In conclusion, the correct measurements options are those that are dimensionally correct.

Electrons travel around the nucleus
The volume of a gas that its pressure increase to 3.4 atm is calculated as follows
By use of boyles law that is P1V1=P2V2
V1=4.0 L
P1=1.1 atm
P2=3.4 atm
V2= P1V1/P2
(1.1 atm x 4.0 L)/3.4 atm= 1.29 L
