Answer:
The importance of significant figures
As stated before, it is important within the science fields that you are not more precise or accurate than the least accurate or precise number. In science, it is generally agreed upon that the last number digit in any figure is filled with uncertainty.
Explanation:
Answer:Minerals form when rocks are heated enough that atoms of different elements can move around and join into different molecules. Minerals are deposited from salty water solutions on Earth's surface and underground
Explanation:
<span>10 g of hexane has a greater volume than 10 g of toluene.
volume of hexane = 15.27 mL
volume of toluene = 11.53 mL
First, look up the density of hexane and toluene.
hexane = 0.6548 g/mL
toluene = 0.867 g/mL
Since hexane has the lower density, the same mass of hexane will have a higher volume than the same mass of toluene. No need for you to actually calculate the volume for the first part of the question.
However, the 2nd part of the question does require you to calculate the volume. That is a simple matter of division.
volume of hexane = 10 g / 0.6548 g/mL = 15.27 mL
volume of toluene = 10 g / 0.867 g/mL = 11.53 mL</span>
Answer:
Tritium
Tritium is a hydrogen isotope consisting of one proton, two neutrons and one electron. It is radioactive, with a half-life of 12.32 years.

The moon exerts pull on the
earth. The pull stretches the earth's watery envelope and creates tidal bulges.
Where the water is thinnest is low tide. The answer is letter A. Moon tides or
lunar tides are caused by the pull of gravity between the moon and earth. The
moon will exert a gravitational pull on earth and the earth also pulls the moon
towards itself. The results is that the moon is near the earth and formation of
oceans tide. Even though the earth can hold any object within its proximity,
the ocean is partly attracted due to its liquid property. At night, the ocean
tends to be attracted to the moon by creating a bulge and assigning it as ‘high
tide’. This is due to the strong gravitational pull of the moon to the earth.
