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

***How many grams of sodium azide are required to form 5. 00 g of nitrogen gas?***
The molar mass of sodium azide is 64. 99 g/mol
The molar mass of nitrogen gas is 28. 00 g/mol
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)

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.

O petrified wood and Tyrannosaurus
Lystrosaurus and Glossopteris are two pieces of fossil evidence support the idea of continental drift.
One of the geologist's first theories about how continents moved over time was continental drift. The science of plate tectonics has been largely supplanted the hypothesis of the continental drift. Alfred Wegener has been most closely associated with the continental drift idea. Wegener released a paper in the early twentieth century describing his notion that continental landmasses were "drifting" across the Earth, occasionally ploughing through seas and into one other. He developed the term "continental drift" to describe this process.
Wegener found similarities in the coasts of eastern South America as western Africa and hypothesised that those countries had originally been part of a supercontinent called Pangaea, which had separated and travelled many kilometres away over geologic time. He also mentioned nearly comparable fossil creatures and rock layers that happened on vastly different continents. Colbert discovered Lystrosaurus fossils in the Transantarctic Mountains of Antarctica. Such fossils belonged to something like a species previously discovered in Africa, proving that the world's two most distant continents were formerly linked.

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

please hurry
Answer:
a process where the products released in one reaction are the stimuli and reactants for another reaction
Explanation:
A chemical reaction is described as a process in which the products promote or spread the reaction, which may accelerate dramatically under certain conditions.
Answer: chain reaction
Explanation: a chain reaction is a series of chemical reactions where the products of the reaction contribute to the reactants of another reaction. as a series of events that are each caused by the previous event. If a trash can falls over and this scares a cat who then jumps and knocks over a glass of water, thats a chain reaction. The trash can fall is the initial event, and the end result is the glass getting knocked over.
