Density is an intensive property of a substance. An intensive property means that it is a physical property that does not depend on the size or the amount of material in the matter. For example, if a diamond is cut in half, the density does NOT change, therefore it is an intensive property.
Answer:
Explanation:
To convert from grams to moles we must use the molar mass, which is found on the Periodic Table.
Use the molar mass as a ratio.
Multiply by the given number of grams: 118
Flip the fraction so the grams of argon will cancel each other out.
The original measurement of grams had 3 significant figures, so our answer must have 3 sig figs.
For the number we calculated, that is the hundredth place. The 7 in the thousandth place tells us to round the 5 to a 6.
There are about <u>2.96 moles of Argon</u> in 118 grams.
The fossil could get damaged and broken into smaller pieces. That is a way it could make it difficult to determine the fossils age.
Answer:
Explanation:
The structures of the starting materials 2‑methylhept‑3‑yne can be seen in the diagram attached below. We will also notice the role of NaNH₂ which acts as a strong base and whose function is to extract acidic proton and form an alkyne as a product.
The reaction with NaNH₂ yields acetylide ion which is then reacted with a straight-chain alkyl halide to form an extended carbon chain.
CHECK THE DIAGRAM BELOW.
Density of boat =
=
= 0.88 g / cm³
Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means,
the boat will NOT sink.B.
