Answers on the right:A balloon containing 0.0400 mol of a gas with a volume of 500 mL was expanded to 1.00 L. Answer the questions and round answers to nearest hundredth place. Which equation should you use to find the amount of gas added?
B. n₂=V₂n₁/V₁
What is the final number of moles?
0.08 mol
__________________________________________________________
Explanation:The ideal gas law is Boyle's law, Charles's law, Gay-Lussac's law, and Avogadro's law combined into one equation. Avogadro's law is V₁/N₁=V₂/N₂, Charles's law is V₁/T₁=V₂/T₂, Gay-Lussac's law is P₁/T₁=P₂/T₂, and Boyle's law is P₁V₁=P₂V₂.
For the balloon problem, B is the correct answer because we are looking for the final moles of gas added. Answer B gives the equation that equals n₂, n₂ means final number of moles. The problem gives us initial volume (500 mL), final volume (1 L), and initial moles amount (0.04 mol). Plug these numbers into the equation, n₂=V₂n₁/V₁, using consistent units. Note that V₁=initial volume, V₂=final volume, n₁=initial moles, and n₂=final moles

Which will boil faster distilled water or salt water and why?
Answers
Answer:
The distilled water will be boiled faster as it does not contain any non - volatile solute.
- The salty water contains different non - volatile salts in it.
- Due to the presence of these salts, its vapour pressure will be decreased and boiling point will be elevated.
- So, salty water will take more time to boil.
- On the other hand, distilled water does not have any such solute and due to this its vapour pressure will not be affected.
- Hence, it will boil fast than salty water.

The question is incomplete, the complete question is;
The half-life of strontium-90 is about 29 years. How many half-lives have elapsed when 6.25% of a strontium- 90 sample remains in the container?
Answer:
4 half lives
Explanation:
From;
N/No = (1/2)^t/t1/2
N= amount of strontium-90 present at time t
No= amount of strontium-90 originally present
t= time taken
t1/2 = half life of strontium-90
But N= 0.0625No
Hence;
0.0625No/No = (1/2)^t/29
0.0625 = (1/2)^t/29
(1/2)^4 = (1/2)^t/29
4 = t/29
t = 4 × 29
t= 116 years
Hence four half lives have elapsed
A presión de 3atm, 7L de un gas a temperatura constante experimenta un cambio ocupando un volumen de 0,5L ¿Cuál será la presión que ejerce? ayuda
Answers
Answer:
La presión que ejerce es 42 atm.
Explanation:
La ley de Boyle relaciona la presión y el volumen y dice que el volumen ocupado por una determinada masa gaseosa a temperatura constante, es inversamente proporcional a la presión.
La ley de Boyle se expresa matemáticamente como:
P*V=k
Ahora es posible suponer que tienes un cierto volumen de gas V1 que se encuentra a una presión P1 al comienzo del experimento. Si varias el volumen de gas hasta un nuevo valor V2, entonces la presión cambiará a P2, y se cumplirá:
P1*V1= P2*V2
En este caso:
P1= 3 atmV1= 7 LP2= ?V2= 0.5 LReemplazando:
3 atm* 7 L= P2* 0.5 L
Resolviendo:
[tex]P2=\frac{3 atm*7 L}{0.5 L}[/tex]
P2= 42 atm
La presión que ejerce es 42 atm.
Answer:10.5
Explanation:
3atm x 7L / 0,5L = 10.5
Quando bajamos el volmen sube la presion y cuando bajamos la presion sube el volumen

Which of the following most likely happens when the volume of a gas increases the number of collisions of gas particles remains same. The number of collisions of gas particles increases. The pressure of the gas remains the same. The pressure of the gas decreases
Answers
Answer:
D. The pressure of the gas decreases!
Explanation:
According to Boyle's Law, there is an inverse relationship between the volume of a gas and its pressure!
So, if the volume of a gas increases, its pressure will decrease; the same thing will happen if the pressure of the gas increases -- the volume will decrease!
↑P↓V and ↓P↑V <---- this is what it would look like visually!!
Hope this helps! :)
When the volume of a gas increases then the pressure of the gas decreases.
What is ideal gas equation?Ideal gas equation is a hypothesis which tells about the behavior of gas in different conditions and it will be represented as:
PV = nRT
From this equation it is clear that pressure and volume are inversely proportional to each other:
P ∝ 1/V
Means if pressure increases ten volume decreases or if pressure decreases then volume increases.
Hence option (4) is correct.

You are a NASCAR pit crew member. Your employer is leading the race with 20 laps to go. He just finished a pit stop and has 5.0 gallons of fuel in the tank. On the way out of the pits, he asks, "Am I going to have enough fuel to finish the race or am I going to have to make another pit stop?" You whip out your calculator and begin your calculations based on your knowledge of stoichiometry. Other information you know is: The car uses an average of 300.0 grams of O2 for each lap. The formula for fuel is C5H12. The fuel has a density of 700 g/gal. What do you tell the driver? (The density can be used as a conversion factor between grams and gallons)
Answers
Answer:
Since there are 3500 g of fuel left in the tank, and he needs only 1687.5 g to complete 20 laps, he has enough fuel to complete the race. I will tell the driver that he does not need to make another pit stop as he has enough fuel to complete the race.
Explanation:
Density = mass / volume
Density of fuel = 700 g/ 1 gal
Therefore, the mass of fuel in 1 gallon = 700 g
The driver has 5.0 gallons of fuel in the tank.
The mass of 5.0 gallons of fuel = 5 × 700 = 3500 g of fuel
Equation of the combustion of fuel, C₅H₁₂ is given below:
C₅H₁₂ + 8 O₂ ---> 6 H₂O + 5 CO₂
1 mole C₅H₁₂ requires 8 moles of O₂
1 mole of C₅H₁₂ has a mass = 72 g
8 moles of O₂ has a mass = 256 g
Therefore, 300 g of O₂ will require 300 × (72/256) g of C₅H₁₂ = 84.375 g of C₅H₁₂
84.375 g of fuel is used by the car per lap;
20 laps will require 20 × 84.375 g of fuel = 1687.5 g of fuel.
Since there are 3500 g of fuel left in the tank, and he needs only 1687.5 g to complete 20 laps, he has enough fuel to complete the race. I will tell the driver that he does not need to make another pit stop as he has enough fuel to complete the race.

What is the molarity if 60.4 grams of hydrochloric acid was added to 505 mL of water?
M
H - 1.0079 g/mol
Cl- 35.453 g/mol
Answers
Answer:
3.29 M
Explanation:
Molarity refers to the molar concentration of a solution and it can be calculated using the formula below:
Molarity (M) = number of moles (n) ÷ volume (V)
According to this question, the mass of HCl was given to be 60.4 grams and the volume of water as 505 mL.
Using mole = mass/molar mass to convert mass of HCl to moles
Molar mass of HCl = 1.0079 + 35.453 = 36.4609g/mol
mole = 60.4g ÷ 36.4609g/mol
mole = 1.66mol
Volume of water = 505mL = 505/1000 = 0.505L
Molarity, M = 1.66 ÷ 0.505
Molarity of HCl solution = 3.29 M

I took the test and it wright
The correct pair that lists a substance that can neutralize [tex]\rm Ca(OH)_2[/tex] and the salt that would be produced from the reaction is HCl and [tex]\rm CaCl_2[/tex].
A reaction is a process that involves the transformation of one or more substances into one or more different substances.
When HCl (hydrochloric acid) reacts with [tex]\rm Ca(OH)_2[/tex] (calcium hydroxide), they undergo a neutralization reaction. The HCl donates a hydrogen ion ([tex]\rm H^+[/tex]) to the [tex]\rm Ca(OH)_2[/tex], resulting in the formation of water ([tex]\rm H_2O[/tex]) and [tex]\rm CaCl_2[/tex] (calcium chloride).
The reaction can be represented as follows:
[tex]\rm 2HCl + Ca(OH)_2\rightarrow 2H_2O + CaCl_2[/tex]
Therefore, HCl is an acid that can neutralize [tex]\rm Ca(OH)_2[/tex] and the salt produced from this reaction is [tex]\rm CaCl_2[/tex].
