the chemical formula must be after balancingknown as 92.55 (mass) of KOH+HCL will produce 74.55 (mass) of salt, KCLhence, 11.2g of KOH and HCL will produce (x)g of saltWhich statement describes absolute and apparent brightness?
NOTES TO TAKE DOWN:
Apparent brightness is a human measurement, and it would change for each star if the measurement were taken from another location. The more precise counterpart of apparent brightness is called absolute brightness (or absolute magnitude) and is the measure of the luminosity of a star, but on a common scale.
ANSWER:
Absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer.

Identify a human activity that impacts the land negativaly. Then describe a positive action that can help reduce the effects caused by the activity
Answer:
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.
What is an ecosystem?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.

How many moles of silver metal are produced from 1.55 moles of copper metal? How many moles of copper(II) nitrate?
Answer:
1. 3.1 moles of silver, Ag.
2. 1.55 moles of Cu(NO₃)₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
Cu + 2AgNO₃ —> Cu(NO₃)₂ + 2Ag
From the balanced equation above,
1 mole of Cu reacted to produce 1 mole of Cu(NO₃)₂ and 2 moles of Ag.
1. Determination of the number of mole of silver (Ag) produced.
From the balanced equation above,
1 mole of Cu reacted to produce 2 moles of Ag.
Therefore, 1.55 moles of Cu will react to produce = 1.55 × 2 = 3.1 moles of Ag.
Thus, 3.1 moles of Ag is produced.
2. Determination of the number of mole of copper(II) nitrate, Cu(NO₃)₂ produced.
From the balanced equation above,
1 mole of Cu reacted to produce 1 mole of Cu(NO₃)₂.
Therefore, 1.55 moles of Cu will also react to 1.55 moles of Cu(NO₃)₂.
Thus, 1.55 moles of Cu(NO₃)₂ is produced

How many molecules are there in 5.9 moles of NaCl?
The number of molecules= 3.55 x 10²⁴
Further explanationGiven
5.9 moles of NaCl
Required
The number of molecules
Solution
The mole is the number of particles(molecules, atoms, ions) 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 5.9 moles :
= 5.9 x 6.02 x 10²³
= 3.55 x 10²⁴
Where does fission regularly occur and what kind of energy is produced?

2:Fission occurs in a nuclear power plant. The energy produced comes in the form of heat.
3:Fission occurs when fossil fuels are burned. The energy can be used to produce electricity.
4:Fission occurs inside the sun. It creates the light and heat that sustain life on Earth.
Answer:
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.

A room is a cube that measures 4 meters in each dimension. If the temperature changes from 10 C to 30 C, and the pressure decreases from 760 mm to 718 mm Hg, would air be trying to enter or leave the room? Show tour work
Answer:
More air will enter the room since the volume of the room increases.
Explanation:
We'll begin by calculating the initial volume (V₁) of the room. This can be obtained as follow
Length (L) of room = 4 m
Initial volume (V₁) =..?
V₁ = L³
V₁ = 4³
V₁ = 64 m³
Next, we shall determine if there is an increase in the volume of the room or not. This can be obtained as follow:
Data obtained from the question include:
Initial volume (V₁) = 64 m³
Initial temperature (T₁) = 10 °C + 273 = 283 K
Final temperature (T₂) = 30 °C + 373 = 303 K
Initial pressure (P₁) = 760 mmHg
Final pressure (P₂) = 718 mmHg
Final volume (V₂) =?
P₁V₁/T₁ = P₂V₂/T₂
760 × 64 / 283 = 718 × V₂ / 303
48640 / 283 = 718 × V₂ / 303
Cross multiply
283 × 718 × V₂ = 48640 × 303
203194 × V₂ = 14737920
Divide both side by 203194
V₂ = 14737920 / 203194
V₂ = 72.53 m³
SUMMARY
Initial volume (V₁) of room = 64 m³
Final volume (V₂) of room = 72.53 m³
From the calculations made above, we can see that the volume of the room increases from 64 m³ to 72.53 m³. Thus more air will enter the room since the volume of the room increases.

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
What does the respiratory system do for
the human body?
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.
brings oxygen into the body
