The answer will be Carbon Molecule
Answer:
Stratosphere
Explanation:
Small storms would be residing in the troposphere but stronger thunderstorms and hurricanes reside in the stratosphere.
Answer:
Approximately
.
Explanation:
Lookup Avogadro's Number:
(three significant figures.)
Lookup the relative atomic mass of
,
, and
on a modern periodic table:
(For example, the relative atomic mass of
is
means that the mass of one mole of
atoms would be approximately
grams on average.)
The question counted the number of
molecules without using any unit. Avogadro's Number
helps convert the unit of that count to moles.
Each mole of
molecules includes exactly
of these
molecules.
molecules would correspond to
of such molecules.
(Keep more significant figures than required during intermediary steps.)
The formula mass of
gives the mass of each mole of
molecules. The value of the formula mass could be calculated using the relative atomic mass of each element:
.
Calculate the mass of approximately
of
:
.
(Rounded to three significant figures.)
Answer:
Chemical reaction are irreversible. Some of the example of chemical reaction are cooking, rusting, and burning. During a chemical reaction, the composition of substances changes and the particles rearrange to form a new substance. The new substance formed after chemical reaction of substance has different physical and chemical properties.
When a chemical reaction occur, the atoms or molecules of the substances change its physical and chemical properties such as while cooking of vegetable, the molecules of vegetable undergo changes in their properties and form a new substance which is different from the earlier.
Answer:
pure substances and mixtures
Explanation:
pure substances are further broken down into elements and compound....... A mixture is composed of different types of atoms or molecules that are not chemically bonded.
