Please help with this question.

What are some of the ways that people can Reduce their use of fossil fuels?

alukav5142 [94]

Answer:

By using renewable energy sources.

Explanation:

You need to satisfy a quota of energy for (whatever country you live in). People do this by using the cheapest way of producing the most energy, the most efficient. Sounds great right? Wrong! It stuffs our atmosphere with harmful gasses like carbon dioxide. You can reduce the use of these fossil fuels by using renewable energy sources such as windmills, watermills, and most notable, solar panels!

Be sure to answer all parts. What is the effect of each of the following on the volume of 1 mol of an ideal gas? (a) The pressur

aksik [14]

Answer

A)The volume decreases by a factor of 4

B), the volume has increased by factor of 2

Explanation:

A)Given:

P1= 760Kpa

P2 =202Kpa

The temperature changes from37C to155C

There is increase In pressure from P1 to P2

P1= 760torr.

We need to convert to Kpa

But, 1atm= 760torr

Then 760torr 101000pa

Then 101000pa = 101Kpa

We need to convert the temperature from Celsius to Kelvin

T1= 37+273= 310K

But from ideal gas, we know that PV = nRT where nR is constant

Where P= pressure

V= volume

T= temperature

n = number of moles

(P1V1/T1)=(P2V2/T2)

V1/V2 = P2/P1 * T1/T2

V1/V2 = (202/101)*(310/155)

V1/V2=4

$V2= V1/4$

Therefore, the volume has decreased by factor of 4

B)

Given:

P1= 2atm

P2 =101Kpa

The temperature changes from 305K to 32C

There is increase In pressure from P1 to P2

P1= 2atm

We need to convert to Kpa

But, 1atm= 760torr

Then 760torr 101000pa

Then 101000pa = 101Kpa

P1= 202.65kpa

We need to convert the temperature from Celsius to Kelvin

T2= 32+273= 305K

But from ideal gas, we know that PV = nRT

Where P= pressure

V= volume

T= temperature

n = number of moles

(P1V1/T1)=(P2V2/T2)

V1/V2 = P2/P1 * T1/T2

V1/V2 = (202/101)

V1/V2 = (101/202.65)*(305/305)

V1/V2 = 1/2

$V2=2V1$

Therefore, the volume has increased by factor of 2

How many liters of 0.37 M solution can be made with 29.53 grams of lithium fluoride.<br> (LiF)?

dsp73

Answer:

V = 3.1 L

Explanation:

Given data:

Molarity of solution = 0.37 M

Mass of LiF = 29.53 g

Volume of solution = ?

Solution:

Number of moles of LiF:

Number of moles = mass/molar mass

Number of moles = 29.53 g/ 25.94g/mol

Number of moles = 1.14 mol

Volume:

Molarity = number of moles of solute / Volume in L

0.37 M = 1.14 mol / V

V = 1.14 mol / 0.37 M

V = 3.1 L (M = mol/L)

The diagram shows the process of the water cycle on Earth. Heat from the Sun causes water to evaporate: the liquid water turns i

astra-53 [7]

The diagram below shows the different aspects of the water cycle, such as how water is observed by plants and how it is carried around by the atmosphere.

The diagram relates to a cactus biome.

Cactuses are still plants,

We have several characteristics that make cactus a plant:

1. Photosynthesis

Unlike other plants that photosynthesize with their leaves, cacti do so with their stems. At night, they take in carbon dioxide, which is then used during the day.

2. The stem succulent

A cactus is classified as a succulent. In other terms, a succulent is a plant that has thick juicy stems or leaves that store water. A cactus stores its water in stems, and some species are adapted to arid areas.

3. Special skin surface

One attribute that makes cacti not lose a lot of water is the fact that they have waxy surfaces that prevent evaporation. Some species also have ribbed surfaces that prevent splitting even when the plant expands during desert rainstorms.

4. Cactus spines

Cacti have spines that protect them from being eaten by animals. The spines also act as insulation during the dry seasons.

How do cactuses survive in the desert?

A cactus is able to survive in the desert due to the following features:

It has long roots that go deep inside the soil for absorbing water.

Its leaves are in the form of spines to prevent water loss through transpiration.

Its stem is covered with a thick waxy layer to retain water.

This shows how cactuses can survive without water and this relates to what the diagram shows however, the diagram shows that rain takes a part in the water cycle, whereas for cactuses, they don't need much water due to their extreme adaptivity.

But there are some similarities too, for example cactuses are still plants so they still photosynthesise and give us oxygen and whatnot.

Forgive me if this is wrong, I tried my best <3 Have a great day

(Forgive me if this is too long just use the important part)
