There are D) 9.51E23

Given

1.58 moles of LiOH

Required

The number of formula units

Solution

The mole is the number of particles(molecules, atoms, ions, formula units) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

So for 1.58 moles :

= 1.58 x 6.02 x 10²³

= 9.5116 x 10²³

There are 5.5 moles of Argon gas in tank

Given

122.6 liters of Argon gas

Required

The number of moles

Solution

Assume at STP

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

So for 122.6 L :

= 122.6 L : 22.4 L

= 5.47 moles ≈ 5.5 moles

Answer:It’s helps use take in fresh air and conduct it to carbon

dioxide.

Explanation:Our respiratory system not only helps us turn air to Co2 the frest air also helps refresh our blood when it passes through our heart.

The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood. The respiratory system also helps to regulate the acid-base level in the blood. lastly, the respiratory system allows us to vocalize by the movement of exhaled air through the larynx.

Pollution

•The number of trips one takes in a car should be reduced.

•Reduce or eliminate fireplace and wood stove use.

•Burning leaves, trash, and other materials should be avoided.

•Using gas-powered lawn and garden equipment should also be avoided.

In an ecosystem, pollution is  a human activity that impacts the land negatively.Minimum use of vehicles and emission of smoke can help reduce the effects caused by the activity.

An ecosystem is defined as a system which comprises of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through  means of nutrient cycles and flow of energy.

Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the ecosystem .Living organisms also influence the quantity of biomass which is  present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

haploid

Explanation:

Meiosis is a type of cell division that occurs during the process of formation of gametes particularly sexually reproducing organisms.

Gametes are reproductive, sex cells that are haploid (having half the number of chromosomes as their parent cell).

Thus, during meiosis a diploid parent cell gives 4 haploid daughter cells, called gametes (such as eggs and sperms).

2:Fission occurs in a nuclear power plant. The energy produced comes in the form of heat.

Explanation:

Nuclear fission regularly occurs in nuclear power plants. The energy produced is in form of heat energy which is used for a wide range of purposes.

Nuclear fission is the radioactive decay process in which a heavy nucleus spontaneously disintegrates into 2 lighter ones and several neutrons with the release of a large amount of energy.

This reaction is utilized by nuclear power plants to generate electricity.

Answer:

A i just did it. And yes i do go to k12

Explanation:

Answer:

2.23L

Explanation:

Using the general gas law as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas constant (0.0821 Latm/molK)

T = temperature (K)

According to the information provided in this question,

Mass of nitrogen = 2800mg

Since 1g = 1000mg

2800mg = 2800/1000

= 2.8g

Using mole = mass ÷ molar mass

Molar mass of nitrogen gas (N2) = 28g/mol

mole = 2.8/28

mole of N2 gas = 0.1mol

Pressure = 98kPa

1 kilopascal (kPa) = 1000pascal (pa)

98kPa = 98 × 1000

= 98000pascal

Since 1 Pascal = 9.869 × 10^-6 atmosphere (atm)

98000pascal = 98000 × 9.869 × 10^-6

= 0.967atm

Temperature = -10°C

Kelvin = °C + 273

Kelvin = -10 + 273

K = 263K

Hence, using PV = nRT

0.967 × V = 0.1 × 0.0821 × 263

0.967V = 2.159

V = 2.159/0.967

V = 2.23

Volume of Nitrogen gas = 2.23 L
