Answer:
Explanation:
cent means “one hundredth”.
the meter is the base unit.
cent is a hundredth.
so there are 100 centimeters in a meter.
If a liquid does not have a constant boiling point but it looks the same throughout, then the liquid is probably a homogeneous mixture. A liquid that does not have a constant boiling point would mean that it is not a pure liquid, it would be a mixture of different substances. As stated, the liquid is observed to be the same all throughout then it most likely is homogeneous. Homogeneous mixture are mixture which has the same composition of the components at any point of the mixture. So, it would have uniform properties as well. Examples of this type of mixture would be soda, coffee, tea and juices.<span />
When should lab participants look at the safety data sheet (sds) of a substance--- before using the substance
Which of the following will be found on a safety data sheet?
The SDS includes information such as the properties of each chemical; the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting the chemical.
Where can safety data sheets be found?
To obtain SDS, get them from the manufacturer. They may be sent with the chemical order (paper copy or e-mail attachment). Otherwise, go to the manufacturer's website and download it or request a copy
What is the purpose of a safety data sheet?
A Safety Data Sheet (formerly called Material Safety Data Sheet) is a detailed informational document prepared by the manufacturer or importer of a hazardous chemical. It describes the physical and chemical properties of the product

The area was probably covered by water. I think
Answer is: density of the talc sample in air is 4,61 g/cm³.
m(talc) = 13,65 g.
d(talc) = 1,75 g/cm³.
V(talc) = m(talc) ÷ d(talc).
V(talc) = 13,65 g ÷ 1,75 g/cm³.
V(talc) = 7,8 cm³.
d(talc in air) = m(talc in air) ÷ V(talc).
d(talc in air) = 35,97 g ÷ 7,8 cm³.
d(talc in air) = 4,61 g/cm³.
