A unit of ppm has an acronym of parts per million. The
equivalent units of ppm is therefore mg/L and mg/kg. So the ppm is:
mass Ca+ = 1.3 g = 1300 mg
ppm = 1300 mg / 3100 kg
<span>ppm = 0.42 ppm</span>
Answer:
. B. The boxes must minimize thermal energy transfer to prevent thermal energy from transferring into the boxes.
Explanation:
If a box is to remain cool, energy transfer into the box must be minimized and energy transfer out of the box must be maximized.
This implies that only a minimal amount of thermal energy can transfer into the box while the box looses heat rapidly. If a box is this designed, it is likely to remain cool.
Matter cannot be created or destroyed in a chemical reaction best describe law of conservation of mass.
<h3>What is law of conservation of mass?</h3>
The law of conservation of mass states that for any system closed Mass can neither be created not destroy. the mass of the system must remain constant over time,.
Therefore, Matter cannot be created or destroyed in a chemical reaction best describe law of conservation of mass.

Nothing is less dense than gas. gas is the least dense form of matter.
Law of conservation of matter: It is the principle that matter can not be destroyed or created and we have a finite and limit amount of matter in the universe.
