The world’s record for the largest cup of coffee was broken on October 152010, with a 2010 gallon cup of coffee in Las VegasNevada. If a cup of coffee contains 237 mL of coffeehow many cups of coffee would be required to fill this enormous coffee cup?
The number of coffee cups that would be required to fill the enormous coffee cup would be 32 cups.
Dimensional analysisThe world's largest cup of coffee can hold 2010 gallons of coffee as recorded in Las Vegas.
A normal coffee cup will only hold as much as 237 mL of coffee. Recall that:
1 gallon = 3.78541 LIf 1 gallon = 3.78541 L
2010 gallons = 2010 x 3.78541
= 7608.6741 L
In other words, the coffee cup with the record size will hold a maximum of 7608.6741 L of coffee while a normal coffee cup will only hold 237 mL. The problem now is the number of number coffee cups that will fill the world's record largest coffee.
7608.6741/237 = 32.10
Therefore, the number of normal coffee cups that would be required to fill the enormous coffee cup would be approximately 32 cups.

0.002 liters of 225 M Na2S solution is required to completely react with 81.8 g Fe(C2H3O2)3
Starting from the balanced equation of the reaction and the molar mass of iron (III) acetate (Fe(C2H3O2)3, first the reacting moles of this compound are determined, then the amount of reacting moles of sodium sulfide (Na2S) is determined and finally the amount of solution that contains said amount of moles.
Balanced equation of the reaction3Na2S + 2Fe(C2H3O2)3 → 6NaC2H3O2 + Fe2S3
Determination of liters of 225 M Na2S solution for a complete reactionThis determination is made in three steps:
Determination of reactant moles of Fe(C2H3O2)3Determination of the reactant moles of Na2SDetermination of the volume of solution with the number of reacting moles of Na2SDetermination of reactant moles of Fe(C2H3O2)3If 233.00 g of Fe(C2H3O2)3 is equivalent to 1 mol of Fe(C2H3O2)3
So 81. 8 g Fe(C2H3O2)3 equals x mol of Fe(C2H3O2)3
X mol of Fe(C2H3O2)3 = 81. 8 g Fe(C2H3O2)3 x 1 mol of Fe(C2H3O2)3 / 233.00 g of Fe(C2H3O2)3
X mol of Fe(C2H3O2)3 = 0.351 mol
Determination of the reactant moles of Na2SIf 2 moles of Fe(C2H3O2)3 react with 3 moles of Na2S
Then 0.351 mol of Fe(C2H3O2)3 reacts with x mol of Na2S
X mol of Na2S = 0.351 mol Fe(C2H3O2)3 x 3 mol of Na2S / 2 mol of Fe(C2H3O2)3 = 0.526 mol
Determination of the volume of solution with the number of reacting moles of Na2SIf there are 225 moles of Na2S in 1 liter of solution
So there are 0.526 moles of Na2S in x liter of solution.
X liter of solution = 0.526 mol of Na2S x 1 liter of solution / 225 mol of Na2S = 0.0023 liters, that is, 2.3 ml

Analysis of a 10.150 grams sample of a compound known to contain only phosphorus and oxygen indicates a phosphorus content of 4.433 grams. What is the empirical formula of this compound
A 10.150 grams sample of a compound containing only phosphorus and oxygen which indicates a phosphorus content of 4.433 grams has the empirical formula P₂O₅.
An Empirical formula is defined as the simplest whole number ratio of different atoms present in the molecule of a compound.
given,
mass of the unknown compound= 10.150 g
mass of phosphorus= 4.433 g
therefore, mass of oxygen
=mass of the unknown compound - mass of phosphorus
=10.150-4.433 g
=5.717 g
we know that
molar mass of oxygen = 16 g/mol
molar mass of phosphorus = 31 g/mol
number of moles of oxygen
=mass/molar mass
=5.717g/16gmol⁻¹
=0.357
number of moles of phosphorus
= mass/molar mass
= 4.433g/31gmol⁻¹
=0.143
Now, we will divide the moles by the smallest number of moles (0.143)
O= 0.357 / 0.143 =2.49≈ 2.5
P= 0.143 /0.143 = 1
now, we will multiply both numbers by 2 to get the simplest whole number ratio

If the garbage truck and minivan in Part A get into an accident with each other, how can safety restraints in a car can save a life? Explain your response using one of Newton’s laws.
Which of Newton’s laws of motion act upon the vehicles at the point of impact? Explain your answer
Newton's law of motion that act upon the vehicles at the point of impact is the second law of motion.
Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum that is produced. Mathematically, we have;
F = m·v - m·u/Δt
Where;
m = The mass of the object
v = The final velocity of the object
u = The initial velocity of the object
Δt = The duration of motion of the object during change in velocity
Therefore, given that the mass, 'M', of the truck is larger than the mass, 'm', of the minivan, where the time of change in velocity Δt, and the initial and final velocities of both automobiles are the same such as in a sudden stop, the garbage ruck will exert more force than the minivan, and therefore, the garbage truck has a greater initial momentum before the automobiles are brought to a stop.

Show all steps in the solution of this question, including proper units, for full credit
3.88 grams of sodium azide are required to form 5.00 g of nitrogen gas.
In order to determine how many grams of sodium azide are required to form 5.00 g of nitrogen gas, we can use the balanced equation for the reaction:
2NaN3 (s) → 2Na (s) + 3N2 (g)
We can start by converting the given amount of nitrogen gas to moles:
5.00 g N2 x (1 mol N2 / 28.00 g N2) = 0.1786 mol N2
We know that the reaction produces 3 moles of N2 for every 2 moles of NaN3 that are used, so we can use the following ratio to find the number of moles of NaN3 required:
0.1786 mol N2 / 3 mol N2 = 0.0596 mol NaN3
Finally, we can convert moles of NaN3 back to grams using the molar mass of NaN3:
0.0596 mol NaN3 x (64.99 g NaN3 / 1 mol NaN3) = 3.88 g NaN3
So, 3.88 grams of sodium azide are required to form 5.00 g of nitrogen gas.

The acceleration of the mass is 8.0 m/s² when an unbalanced 16.0 N force is applied to a 2.0 kg mass.
To calculate the acceleration of the mass, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).
We know that the force acting on the object is 16.0 N, and the mass of the object is 2.0 kg. So, we can use the equation to solve for the acceleration:
a = F ÷ m
where, a = acceleration, F = force (16.0 N), m = mass (2.0 kg)

Because cheese production in the United States is substantially higher than in Italy, we may assume that the United States can offer this commodity to other nations without jeopardizing its consumption. However, tomato output in the United States is the same as in Italy, but because the United States is a larger country than Italy, tomato consumption in the country may be affected.
As a result, if tomatoes are obtained from another nation, tomato consumption in the United States may surpass the PPC of tomatoes. This may be accomplished through barter, with the United States supplying cheese to Italy and Italy supplying tomatoes to the United States.
