When pumping air into a tire, you have to pull back on the pump plunger to fill the pump with air. This increases the volume of the air inside the pump. This increase in volume has what effect on the gases inside the pump?
Question 9 options:
the gas molecules inside the pump are able to spread out more which decreases the pressure of the gas.
the gas molecules inside the pump get compressed and packed closer together which decreases the pressure of the gas.
the gas molecules inside the pump are able to spread out more which increases the pressure of the gas.
the gas molecules inside the pump get compressed and packed closer together which increases the pressure of the gas.
Answer:
Pulling back on the plunger allows you to put in more air into the pump and the more air you have inside a fixed volume, the greater the pressure becomes. (D)
3.00 L of a gas is collected at 150 K and then allowed to expand to
15.0 L. What must the new temperature be in degrees C in order to
maintain the same pressure (as required by Charles' Law)?
Answer:
477 ºC
Explanation:
on an isobaric process, an increase on the volume implies an increase on the temperature:
V1/T1 = V2/T2
T2 = V2T1/V1 = 15.0 L×150 K/3.00 L = 750 K
t/ºC = T/K - 273 = 750 K/K - 273
t = 477 ºC
V1: initial volume
T1: initial temperature
V2: final volume
T2: final temperature

Which is NOT true of the Sc3+ ion?
Multiple choice question.
A)
It is a scandium ion with three positive charges.
B)
It was formed by the loss of 4s and 3d electrons.
C)
It has the same electron configuration as Ar.
D)
It is considered to be a different element than a neutral Sc atom.
Answer:
D. It is considered to be a different element than a neutral Sc atom.
The statement i.e. not true of the Sc3+ ion is that it is considered to be a different element than a neutral Sc atom.
The statements that should be considered as true regarding the Sc3 + ion is as follows:
It represents the scandium ion having 3 positive charges.It is created via the loss of 4s & 3d electrons. And, it contains the similar configuration as treated as Ar.Therefore we can conclude that the statement i.e. not true of the Sc3+ ion is that it is considered to be a different element than a neutral Sc atom.

The power of the crane was 68600 W
Caculate the time taken for the crane to do 3430000 J of work
Give the unit
Answer:
t = 50 s
Explanation:
P = W/t
Solving for t,
t = W/P = (3430000 J)/(68600 Watts)
= 50 s
Note: 1 Watt = 1 J/s
According to the question, the time that is taken by the crane which has the power of 68600 W to 3430000 J of work is 50 seconds.
What is Power?Power may be defined as the amount of energy that is significantly transmitted or converted per unit of time. In a more simple sense, it is also characterized as the measure of the rate of doing work.
According to the question,
The power of the crane = 68600 W.
The amount of work that the crane has to do = 3430000 J.
Time may be calculated with the help of the following formula:
Power = Work/time.Time = Work/power = 3430000 J/68600 W = 50 seconds. (where 1 W = 1 J/sec).Therefore, according to the question, the time that is taken by the crane which has the power of 68600 W to 3430000 J of work is 50 seconds.

Calculate the moles of of Fe that would be needed to form 336 grams of Cl2 (round your answer to 2 decimals)
2Fe + 3Cl2 → 2FeCl3
Answer:
6.32 moles of Fe
Explanation:
The given chemical equation is presented as follows;
2Fe + 3Cl₂ → 2FeCl₃
The mass of Cl₂ in the reaction = 336 grams
The molar mass of chlorine gas Cl₂ = 35.435 g/mol
The number of moles, n = Mass/(Molar mass)
The number of moles of Cl₂ in the reaction, n = 336 g/(35.435 g/mol) ≈ 9.842 moles
From the given reaction, 3 moles of Cl₂ react with 2 moles of Fe to produce 2 moles of FeCl₃
By the law of definite proportions, we have that 9.482 moles of Cl₂ will react with approximately 9.482 × 2/3 = 6.32 moles of Fe to produce approximately 6.32 moles of FeCl₃
Therefore, approximately 6.32 moles of Fe will be required to react with 336 grams of Cl₂.

Answer:
36.4cm2
Explanation:
I have 3 questions that I will need help from you. 1. The weight of a millimeter of (NH4)2 HPO4 is? 2. How many moles of alanine, C3H7NO2 are there in 159g of alanine? And 3. Nitric acid is a very important industrial chemical. 1.612 * 10^10 pounds of it were produced in 1992. If the density of nitric acid is 12.53 pounds/gallon. What volume would be occupied by this quantity. (1 gallon =3.7854liters)
Answer:
1. m(NH₄)₂HPO₄ = 1.62 g
2. molesC₃H₇NO₂ = 1.79 moles
3. V = 4.87x10⁹ L
Explanation:
These questions are pretty easy to solve, using the correct expressions and formula.
1. To do this, we just need the density of the (NH₄)₂HPO₄. In this case, the reported density is 1.62 g/mL, therefore:
d = m/V (1)
Where:
d: density (g(mL)
m: mass of the compound (g)
V: volume of the compound (mL)
As we already have the volume, we can solve for m:
m = d * V (2)
m = 1.62 * 1
m(NH₄)₂HPO₄ = 1.62 g2. To do this, we need the atomic weights of each element that composes the alanine.
C: 12 g/mol; H: 1 g/mol; N: 14 g/mol; O: 16 g/mol
With these atomic weight, let's determine the molar mass of alanine:
MM C₃H₇NO₂ = 3(12) + 7(1) + 14 + 2(16) = 89 g/mol
Now to get the moles, we use the following expression:
moles = m/MM (3)
moles = 159 / 89
molesC₃H₇NO₂ = 1.79 moles3. We have the mass and density of the nitric acid, we just solve for Volume from expression (1) of part 1:
V = m/d (3)
V = 1.612x10¹⁰ pounds / 12.53 pounds/gallons
V = 1.287x10⁹ gallons
Converting this to liters:
V = 1.287x10⁹ * 3.7854
V = 4.87x10⁹ LHope this helps
