b. compression only
c. compression and rarefaction
d. compression, rarefaction, and triangulation
Answers
Longitudinal wave has two features which include:
A compression-- the part of the wave which is pressed together.
A rarefaction-- the part of the wave that is the most spread apart.

A substance that can donate a pair of electrons to form a covalent bond is known as a(n) _____ base.
Answers
Answer: Option (A) is the correct answer.
Explanation:
A compound is a substance which contains two or more different atoms combined together.
Sodium is found as sodium chloride in nature. Sodium chloride is also known as common salt.
As it contains a sodium atom combined to a chlorine atom, therefore, it is a compound.
Thus, we can conclude that sodium is the element that is found in nature only in compounds.

The given question is incomplete. But the complete question is this:
A mixture of and
is passed over a nickel catalyst at 1000 K. The emerging gas is collected in a 5.00-L flask and is found to contain 8.62 g of CO, 2.60 g of
, 43.0 g of
, and 48.4 g of
. Assuming that equilibrium has been reached, calculate
for the reaction.
Explanation:
As the given reaction is as follows.
And, we know that
No. of moles =
Therefore, calculate the moles as follows.
Moles of =
= 2.6808 mol
Moles of =
= 2.6866 mol
Moles of CO =
= 0.307747 mol
Moles of =
= 1.2897 mol
As, we know that
Concentration =
Given volume = 5 L
Hence, calculate the concentration of given species as follows.
Conc. of
= 0.5361
Conc. of
= 0.5373
Conc. of CO =
= 0.06155
and, Conc. of
= 0.2579
Now, expression for equilibrium constant for the given reaction is as follows.
Now, putting the given values into the above formula as follows.
Also, we know that
Consider the equation
Calculate change in moles of gas as follows.
change in gas moles (dn) = 1 + 3 - 1 - 1
dn = 2
As,
It is given that,
T = 1000 K, R = 0.0821
So,
= 24.70
Thus, we can conclude that value of for the reaction is 24.70.

Answer:
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
Acid rain affects nearly everything. Plants, soil, trees, buildings and even statues can be transformed by the precipitation.

The correct answer is False
Explanation:
A limiting factor refers to a condition that stops or limits the growth of a population of any species. Some of these factors include the availability of sources such as food, shelter or water; predation; natural weather conditions; natural disasters; and competence.
The previous idea implies food is not the only factor or condition that would stop or limit the growth of a population but there are many other factors that could prevent a population from growing too large, this includes abiotic factors (nonliving condition) such as weather and biotic factors (living condition) such as competition with other species or individuals or predation.
Food is not the only limiting factor that keeps populations from growing too large. This statement is false.
Populations are regulated by a variety of factors, including but not limited to food availability. These factors can be categorized into two main types: density-dependent and density-independent factors.
Density-dependent factors are influenced by population size and include factors such as competition for resources (including food), predation, disease, and territoriality.
As a population grows, competition for limited resources, including food, increases. This can lead to reduced growth, increased mortality, and ultimately limit the population's size.
Thus, while food availability is an important factor in population dynamics, it is not the sole limiting factor. Other ecological factors and interactions within the ecosystem play significant roles in regulating population size and preventing populations from growing too large.
