Answer:
The correct answers are:
a) 180 g
b) 93.7 cm³
Explanation:
The density of a substance is the mass of the substance per unit of volume. So, it is calculated as follows:
density= mass/volume
From the data provided in the problem:
density = 0.8 g/cm³
a) Given: volume= 225 cm³
mass= density x volume = 0.8 g/cm³ x 225 cm³ = 180 g
b) Given: mass= 75.0 g
volume = mass/density = 75.0 g/(0.8 g/cm³)= 93.75 cm³≅ 93.7 cm³
Answer:
No. Because a pure substance, no matter if an element, compound, it can only contain one kind of particle .
Explanation:
Answer:
Both
Explanation:
Depends on which reaction reffered
I believe the answer is a. A passive prosthesis
Prosthesis is used to replace a part of the patient. Some prosthesis powered by external source that allow it to do some degree of movement. Passive prosthesis doesn't have electronic or mechanic part, which makes their function is more to be cosmetic than function.
