Answer:
speed and velocity, c would be my guess
This is an example of conduction
Ca(NO3)2(aq) + Na2CO3(aq) → 2NaNO3 + CaCO3⬇. NaNO3 is solution so CaCO3 is the precipitate formed.
A Safety Data Sheet (SDS) provides even more information on chemicals than a label: True.
<h3>What is a
Safety Data Sheet (
SDS)?</h3>
A Safety Data Sheet (SDS) can be defined as a text-based document (bulletin) that is developed to provide more information with respect to the chemical and physical properties of a chemical compound, substance or equipment such as:
Additionally, a Safety Data Sheet (SDS) contains information on the potential health hazards and safety precautions for proper use, handling, storage and transportation of a chemical compound, substance or equipment.
In conclusion, we can deduce that a Safety Data Sheet (SDS) provides even more information on chemicals than a label, which only contains lesser information about a product.

Refractive index(n)= speed of light in vacuum/ speed of light in medium.
Since refractive index is 1.11, and usually we know that the speed of light is 300,000km/s, simply divide 300,000km/s over 1.11. That is, 270,270.2703 when simply rounding, its 270,270 km/s.
