Another way to say Density is Density
Density is an intensive property as it does not depend on the quantity of the substances Whereas mass and volume are extensive property. The density is mass divided by volume. the correct option is option A.
What is density?Density tells about the compactness of the substances, how much dense is the substances in other words. Object that is more denser than water they just sink in the water. Density is mass divided by volume.
Mathematically, density can be written as : Density = Mass of the substance÷ volume marked on the graduated cylinder. Density is directly proportional to mass and inversely proportional to volume. Density of water is 1 gram per cubic centimeter.
Therefore, density is mass divided by volume. the correct option is option A.

rect number of sig figs. show work!
Answers
Answer:p=m/v
p=(292.2-130.2)/200
p=0.8100g/ml
Explanation:
Density of a substance is the ratio of its mass to volume. The density of the oil filled in a 200.01 ml beaker is 0.815 g/ml.
What is density?Density of a substance is the mass per volume. Thus we het how much of its particles are located per one unit of volume.
Mathematically density can be written as mass/ volume. The mass of the beaker containing oil is given as 293.2 g. The mass of beaker itself is 130.2 g. Hence, mass of oil is 293.2 - 130.2 = 163 g.
Volume of the oil is 200 ml. Thus density is 163 g/200 ml = 0.815 g/ml.
Hence, the oil in the beaker with 200 ml volume and 163 g mass have a density of 0.815 g/ml.

A reaction occurs that results in a molecule with two atoms of the same element. The atoms share six electrons. Which molecule could be the product of the reaction?
Si2
N2
O2
F2
Answers
Answer:
n2 is correct
Explanation:
i took it just now. :)
The product of this reaction could be N2.
Among the options, only atoms of nitrogen have five electrons on their outermost shell.
The fact that they have five electrons in their outermost shells implies that they can combine by sharing six electrons in a triple bond.
When this occurs, each of the nitrogen atoms involved in the bond now has an octet of electrons. Hence, the product formed when the atoms share six electrons. Which molecule could be the product of the reaction is N2.

The rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.
What are rock cycle?The rock cycle is defined as the process through which the three main rock types i.e. igneous, metamorphic and sedimentary rock transfer from one type to another type.
The plate tectonics is defined as a theory that earth's outer shell is divided into large slabs of solid rocks known as "plates" that glide over earth mantle, the rocky inner layer above earth's core.
Thus, the rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.
