It takes 2 g of chlorine to sanitize 1,000,000g of water. How much chlorine will it take to sanitize a 40,000-gallon pool? ( 1 gallon =3.7L; the density of water is 1.0g/ml ) Show your work
Answer:
0.1g (Gallon) of chlorine
Explanation:
Formula
1 gallon = 3.7L; the density of water is 1.0g/ml
Given
2g (gallon) of chlorine to sanitize = 1,000,000g (gallon) of water
Solve
If 2g (gallon) chlorine = 1,000,000g (gallon)
∴, ? chlorine = 40,000
The First step; set up an equation
1000000/2 = 40000/?
The Next step; divide 1 million to 2
1000000 ÷ 2 = 500000
Then, divide the result by 40000
40000 ÷ 500000 = 0.08
In the nearest unit that is 0.1
Therefore, it will take 0.1g (gallon) of chlorine to sanitize a 40,000-gallon pool.
Answer:
296
Explanation:
1 gallon = 3.7 L
40,000 gallon
= 40,000 × 3.7
= 148,000 L
1 g = 1 / 1000 L
1,000,000 g
= 1,000,000 / 1000
= 1,000 L
Let x be the amount of chlorine that will it take to sanitize a 40,000-gallon pool.
2 : 1,000 : : x : 148,000
2 / 1,000 = x / 148,000
x × 1,000 = 2 × 148,000
x = ( 2 × 148,000 ) / 1,000
= 2 × 148
x = 296 g
Therefore,
296 g of chlorine will it take to sanitize a 40,000-gallon pool.

What does q = 0.75 g x 0.897 J/g•°C x 22°C equal?
Answer:
14.8005 Joules
Explanation:
This question is describing the calculation for the amount of heat (Q) a substance absorbs or releases. The amount of heat, Q, is calculated using the formula:
Q = m × c × ∆T
Where;
Q = amount of heat (Joules)
m = mass of substance (g)
c = specific heat of substance (J/g°C)
∆T = change in temperature of substance i.e. final temperature - initial temperature (°C).
According to this question, the following expression is given:
q = 0.75 g x 0.897 J/g•°C x 22°C
To calculate this further, this will equal to: 14.8005
This means that the amount of heat, q, absorbed or released by that substance is equal to 14.8005 Joules.

Calculate the molar mass of a sample if a single molecule weighs 2.55 x 10^-23 g.
molar mass= energy x mass= 10 x 2.55 x 10^-23
Avogadro's number (NA) or Avogadro's constant (6.0221 x 10^23). The term "mole" is defined as that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram.
What is Avogadro's number?The number of molecules in one mole is 6.022 * 10^ 23 numbers. The molecular mass of the molecule is 2.55 x 10^-23
Molar mass can be defined as 'mass per mole.' In other words, molar mass is the sum of the mass of all the atoms found in one mole's worth of a substance. It is expressed in units of grams per mole.
Molar mass is depicted for elements or molecules. In the case of single elements or individual atoms, the molar mass would just be the element's mass expressed in atomic mass units.
Molar mass = 2.55 x 10^-23/ 6.022 * 10^ 23
= 0.423
Therefore, Avogadro's number (NA) or Avogadro's constant (6.0221 x 10^23). The term "mole" is defined as that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram.

Answer:
44.9g
Explanation:
You have to convert grams of CH4 to moles, use the mole-to-mole ratio of CH4 to water, and convert back to grams.
(20.0g CH4)(1 mol CH4/16.04g)(2 mol H2O/1 mol CH4)(18.01 g H2O/ 1 mol) = 44.9127 g

When 2.0 g copper is heated with an excess of sulfur, copper (I) sulfide is the product. What is the mass of the copper (I) sulfide produced? (mass to mass)
Answer: Mass is 2.50 g
Explanation: reaction 2 Cu + S ⇒ Cu2S
Amount of Cu = m/M = 2.00 g /63.55 g/mol= 0.03147 mol
Amount of Cu2S = 0.5 n(Cu) = 0.01574 mol
M(Cu2S)= 159.17 g/mol, m = n·M

Adiabatic process is a process in which _ is constant (a) temperature (b)volume (c)pressure (d) heat
Answer: Adiabatic process is a process in which heat is constant
Explanation:
The processes in which temperature remains constant is called isothermal process.
The process in which Volume remains constant is called isochoric process.
The process in which pressure remains constant is called isobaric process.
The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.

Why do North and South Pole have different winter times?
The two poles have different location.
North Pole is found in the Western Hemisphere.
The tilt of the Earth towards the Sun changes throughout the year.
North Pole is found in the Northern Hemisphere.
Answer:
Explanation:
Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don't get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn't come up at all for months at a time.
Answer:
The tilt of the Earth towards the Sun changes throughout the year.

Create the Equation: How many grams of Aluminum Chloride would be made from 42.7 L of Chlorine gas at STP reacting with 50.0 g of Aluminum?
Answer: 169.3 g of [tex]AlCl_3[/tex] will be produced
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
moles of [tex]Al[/tex]
[tex]\text{Number of moles}=\frac{50.0g}{27g/mol}=1.85moles[/tex]
moles of [tex]Cl_2[/tex]
According to ideal gas equation:
[tex]PV=nRT[/tex]
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 42.7 L
n = number of moles = ?
R = gas constant =[tex]0.0821Latm/Kmol[/tex]
T =temperature =[tex]273K[/tex] (at STP)
[tex]n=\frac{PV}{RT}[/tex]
[tex]n=\frac{1atm\times 42.7L}{0.0820 L atm/K mol\times 273K}=1.90moles[/tex]
[tex]2Al+3Cl_2\rightarrow 2AlCl_3[/tex]
According to stoichiometry:
3 moles of [tex]Cl_2[/tex] reacts with = 2 moles of aluminium
Thus 1.90 moles of [tex]Cl_2[/tex]reacts with= [tex]\frac{2}{3}\times 1.90=1.27[/tex] moles of aluminium
Thus [tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product.
As 3 moles of [tex]Cl_2[/tex] give = 2 moles of [tex]AlCl_3[/tex]
Thus 1.90 moles of [tex]Cl_2[/tex] give =[tex]\frac{2}{3}\times 1.90=1.27moles[/tex] of [tex]AlCl_3[/tex]
Mass of [tex]AlCl_3=moles\times {\text {Molar mass}}=1.27moles\times 133.34g/mol=169.3g[/tex]
Thus 169.3 g of [tex]AlCl_3[/tex] will be produced from the given masses of both reactants.
