Answer:
b. cost to implement conservation policies
Explanation:
Answer: Urbanization implications
Environmental implications
Benefit vs The cost
Explanation:
Conservation involves preservation of organisms and their natural habitat to encourage biodiversity and reduces the risk of extinction.
Urbanization involves the loss of organism’s natural habitat due to deforestation and building of more structures such as buildings and road structures. Government must consider before passing conservation policies if the urbanization will have a bigger impact than conservation.
Environmental implications is also taken into account as the environment is where we live and makes it very important to ensure there are no negative effects.
The benefit and cost are weighed and the one with a lower cost and higher benefit is usually embraced.

**Please answer quickly!** 5.1169 mol of Ne is held at 0.9148 atm and 911 K. What is the volume of its container in liters?
Answer:
418.352441397 Liters
Explanation:
You start off with your equation of PV=nRt, where P= Pressure, V= Volume, n= The amount of moles, R= the gas constant which is 0.0821, and t= The temperature.
You are solving for volume so you would divide the left side by P so you can isolate the Volume. Now you have V=nRt/P.
Next you would fill in all of the variables. n=5.1169, R=0.0821, t=911K, and P=0.9148atm.
You would get the equation V=(5.1169*0.0821*911)/0.9148
Your final answer would be 418.352441397 Liters, or rounded to 418.35 Liters.
The volume of the container is 418.15 L
Ideal gas lawFrom the question, we are to determine the volume of the container
From the ideal gas equation, we have that
PV = nRT
Where P is the pressure
V is the volume
n is the number of moles
R is the gas constant ( R = 0.08206 L.atm.mol⁻¹.K⁻¹)
and T is the temperature
From the given information
P = 0.9148 atm
n = 5.1169 mol
T = 911 K
Putting the parameters into the formula, we get
0.9148 × V = 5.1169 × 0.08206 × 911
Then,
[tex]V = \frac{5.1169 \times 0.08206 \times 911}{0.9148}[/tex]
V = 418.15 L
Hence, the volume of the container is 418.15 L

Why alcohol is weaker acid than water
Answer:
ACIDS ARE WEAKER THAN WATER
Explanation:In general, alcohols are weaker acids than water because the OH group in alcohols is less polar than the OH group in the water. The electron releasing nature of the R group in alcohols decreases the polarity of the OH bond, which in turn decreases the acid strength of alcohols.
Derrick decided to research what factors might affect the properties of the solubility of a solution. After completing his research, Derrick knew that several factors affected the properties of solubility. Explain the factors that affect the properties of the solubility of a solution.
Answer:
Solubility refers to the maximum amount of solute that dissolves in a given amount of solvent at a particular temperature Factors Affecting Solubility 1. Effect of Temperature For some substances to dissolve in a given solvent, heat is absorbed. The reaction is endothermic. In this case, an increase in temperature increases solubility.
Explanation:
Solubility of a solution is affected by properties like temperature and pressure.
What is solubility?Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Compound B is an ionic compound as it is hard,brittle and conducts electricity.
What is an ionic compound?Ionic compound or electrovalent compound is a type of compound which is formed between two elements when there is an exchange of electrons which takes place between the atoms resulting in the formation of ions.
When the atom looses an electron it develops a positive charge and forms an ion called the cation while the other atom gains the electron and develops a negative charge and forms an ion called the anion.
As the two atoms are oppositely charged they attract each other which results in the formation of a bond called the ionic bond.They are hard, malleable, ductile and good conductors of heat and electricity.They have high boiling points.

Answer
D. Acid rain reacting with limestone bedrock.
Explanation:
- Brief Description:
A chemical reaction occurs when acidic rainfall falls on limestone or chalk. During the process, new, soluble compounds are produced. These disintegrate in the sea and are washed away, weathering the rock. Some forms of rock are resistant to chemical weathering. When rain falls from the sky onto a limestone (CaCO3) statue, a reaction between sulphuric acid and calcium carbonate happens. Calcium sulfate is formed as a result of this process (CaSO4). Because calcium sulfate is soluble in water, the statue will ultimately disintegrate. Limestone is chemically worn through the carbonation process. Rainwater collects carbon dioxide as it travels through the atmosphere, forming a weak carbonic acid. Water and carbon dioxide react to generate a mild carbonic acid. The fractures in the limestone are acted upon by this mild carbonic acid. Many weak acids, such as carbonic acid, are found in water. When carbon dioxide gas from the atmosphere combines with rainfall, a weak but copious acid is created. Other forms of acid rain are produced by sulfur dioxide and nitrogen gases, which function as chemical weathering agents.- Chemical WeatheringChemical weathering is generally the most active and effective weathering process. Water within soil or stone dissolves minerals of soil, softens minerals that absorpb the water, and dissolves carbondioxide.Chemical weathering is the breakdown of rock by chemical processes. Water, air, and chemicals released by organisms cause chemical weathering of rocks when they dissolve the minerals in a rock.- Carbon Dioxide-Bicarbonate-Carbonate Equilibrium
The carbon dioxide/bicarbonate/carbonate buffer is an essential buffer in surface waters. When water is in equilibrium with both CO2 from the atmosphere and carbonate-containing rock, its pH is buffered to 8.3, which is close to the pKa of the weak acid bicarbonate HCO3- (pKa = 8.4).- Acid Rain The production of nitric and sulfuric acids in our atmosphere causes acid rain. These chemicals are strong acids that are very soluble in water and dissolve in cloud water droplets.The majority of nitrogen and sulfur oxides are caused by human activity. Electric utilities (60 percent), industrial combustion (17 percent), and industrial processes are the principal sources of sulfur dioxide emissions (8 percent ). Transportation, with internal combustion engines, accounted for more than half of all NOx emissions, with additional emissions from electric utilities (26 percent) and industrial combustion accounting for the remainder (14 percent ). Agricultural operations, particularly manure management, are the biggest source of ammonia emissions, but industry and transportation also emit some ammonia. Acid rain leads to the acidity of lakes and streams, as well as the degradation of trees at high elevations and vulnerable forest soils.- Effect of LimestoneCalcium carbonate, often known as [Ca][CO3], is a common mineral. One well-known form of calcium carbonate is limestone. Acids in acid rain increase calcium carbonate breakdown by interacting with the carbonate anion.This results in a bicarbonate solution. Because surface waters are in balance with atmospheric carbon dioxide, the concentration of carbonic acid, H2CO3, in the water remains constant.Because the minerals react with the excess acid, the presence of limestone and other calcium carbonate rock in lakes and streams helps to maintain a steady pH. However, acid rain can finally overwhelm the surface water's buffering ability.Once nonrenewable resources like oil, natural gas and uranium are used up, there ___________ be any more in your lifetime. will or wont?

To deplete this gas, they use it in cars, stoves, etc. and they use it up to where there can be no more gas left.
