Answer: The given statement is false.

Explanation:

When there occurs unrestricted growth and development in number of urban areas for housing, commercial development, roads etc then it is known as urban sprawl.

Hence, when there will be more population in an urban area then there will be more urban sprawl because then there will be more demand for facilities.

Thus, we can conclude that the statement increase in the population of people living in urban areas will cause a decrease in urban sprawl, is false.

The acid-dissociation constant for benzoic acid (C6H5COOH) is 6.3×10−5. Calculate the equilibrium concentration of H3O+ in the s

raketka [301]

Answer : The equilibrium concentration of $H_3O^+$ in the solution is, $2.1\times 10^{-3}M$

Explanation :

The dissociation of acid reaction is:

$C_6H_5COOH+H_2O\rightarrow H_3O^++C_6H_5COO^-$

Initial conc. c 0 0

At eqm. c-x x x

Given:

c = $7.0\times 10^{-2}M$

$K_a=6.3\times 10^{-5}$

The expression of dissociation constant of acid is:

$K_a=\frac{[H_3O^+][C_6H_5COO^-]}{[C_6H_5COOH]}$

$K_a=\frac{(x)\times (x)}{(c-x)}$

Now put all the given values in this expression, we get:

$6.3\times 10^{-5}=\frac{(x)\times (x)}{[(7.0\times 10^{-2})-x]}$

$x=2.1\times 10^{-3}M$

Thus, the equilibrium concentration of $H_3O^+$ in the solution is, $2.1\times 10^{-3}M$

The air all around us is a mixture of gasses containing nitrogen, oxygen, carbon dioxide, argon

KiRa [710]

Answer:

Total pressure = 4.57 atm

Explanation:

Given data:

Partial pressure of nitrogen = 1.3 atm

Partial pressure of oxygen = 1824 mmHg

Partial pressure of carbon dioxide = 247 torr

Partial pressure of argon = 0.015 atm

Partial pressure of water vapor = 53.69 kpa

Total pressure = ?

Solution:

First of all we convert the units other into atm.

Partial pressure of oxygen = 1824 mmHg / 760 = 2.4 atm

Partial pressure of carbon dioxide = 247 torr / 760 = 0.325 atm

Partial pressure of water vapor = 53.69 kpa / 101 = 0.53 atm

Total pressure = Partial pressure of N + Partial pressure of O + Partial pressure of CO₂ + Partial pressure of Ar + Partial pressure of water vapor

Total pressure = 1.3 atm + 2.4 atm + 0.325 atm + 0.015 atm + 0.53 atm

Total pressure = 4.57 atm

Why is fossil fuel considered a nonrenewable energy source?

IRINA_888 [86]

Answer:

$\boxed {\tt Takes \ many \ years \ to \ replenish}$

Explanation:

A nonrenewable is a resource that cannot quickly be regenerated. A nonrenewable resource will eventually run out, and it cannot be remade for many years.

For example, fossil fuel is formed from fossils after millions of years of heat and pressure turn them into fuel. Since they take many years to create, they are a nonrenewable energy source.
