The table below contains concentration and rate data for a reaction involving three reactants. Use these data to determine the overall order of the reaction and the order with respect to M, N, and P.
Answer:
The order of reaction with respect to M, N, and P are 1, 0, and 3, respectively.
The overall order of reaction is 4.
Explanation:
We are given a table containing the concentrations of M, N, P, and the rate of the reaction, and we want to determine the overall order of the reaction and the order with respect to each reactant.
To do so, we can select two experiments from the list where two of the reactant concentrations are held constant and only one changes.
From trials 1 and 2, we can see that holding [N] and [P] constant while doubling [M] doubles the rate.
Therefore, because the rate is directly proportional to M, the reaction is first order with respect to M.
From trials 2 and 3, we can see that holding [M] and [P] constant while doubling [N] does not affect the rate.
Therefore, the reaction is zero order with respect to N.
From trials 1 and 4, we can see that holding [M] and [N] constant and doubling [P] leads to a eight-fold increase (2.6/0.32 ≈ 8).
Therefore, the reaction is third order with respect to P (2³ = 8).
Hence, our rate law is:
[tex]\displaystyle \text{Rate} = k[M]^1[N]^0[P]^3[/tex]
Where the order of reaction with respect to M, N, and P are 1, 0, and 3, respectively.
And the overall order is the sum of each individual reaction orders, or 4.

Starting with 700.0 grams of calcium phosphate and assuming excess silicon dioxide and carbon,
how many moles of phosphorus will be produced?
Taking into account the reaction stoichiometry, 0.1129 moles of P₄ is required to react with with 700.0 grams of calcium phosphate.
Reaction stoichiometryIn first place, the balanced reaction is:
2 Ca₃(PO₄)₂ + 6 SiO₂ + 10 C → 6 CaSiO₃ + 10 CO + P₄
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Ca₃(PO₄)₂: 2 moles SiO₂: 6 moles C: 10 moles CaSiO₃: 6 moles CO: 10 molesP₄: 1 moleThe molar mass of the compounds is:
Ca₃(PO₄)₂: 310 g/moleSiO₂: 60 g/mole C: 12 g/moleCaSiO₃: 116 g/moleCO: 28 g/moleP₄: 124 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
Ca₃(PO₄)₂: 2 moles ×310 g/mole= 620 gramsSiO₂: 6 moles ×60 g/mole= 360 grams C: 10 moles ×12 g/mole= 120 gramsCaSiO₃: 6 moles ×116 g/mole= 696 gramsCO: 10 moles ×28 g/mole= 280 gramsP₄: 1 mole ×124 g/mole= 124 gramsMoles of phosphorus P₄ producedThe following rule of three can be applied: If by reaction stoichiometry 620 grams of Ca₃(PO₄)₂ produces 1 mole of P₄, 70 grams of Ca₃(PO₄)₂ produces how many moles of P₄?
[tex]moles of P_{4} =\frac{70 grams of Ca_{3}(PO_{4} )_{2}x1 mole of P_{4} }{620 grams of Ca_{3}(PO_{4} )_{2}}[/tex]
moles of P₄= 0.1129 moles
Finally, 0.1129 moles of P₄ is required to react with with 700.0 grams of calcium phosphate.

The spontaneity of a reaction depends on the temperature, enthalpy and entropy.
What is spontaneity of a reaction?A reaction is said to be spontaneous if it can proceed on its own without a further input of energy.
In the first case, when the enthalpy is less than zero and the entropy is greater than zero, the reaction is spontaneous at all temperatures.
In the second case, when the enthalpy greater than zero and the entropy is greater than zero, the reaction needs to proceed at high temperatures to be spontaneous.
In the third case, when the enthalpy is greater than zero and the entropy is less than zero, the reaction ought to proceed at low temperature in order to be spontaneous.

Q4: People have concerns about the use of slash and burn partly because it affects the carbon cycle in multiple ways. What are two of those ways
From what we know, we can confirm that people have concerns about the use of slash and burn because it creates more CO2 and decreases the natural ability to remove it from the air.
Why is slash and burn so environmentally harmful?This has to do with CO2 emissions. The slash and burn technique involves slashing away and burning large areas of green land in order to create farmland. This creates large amounts of CO2 through combustion that are released into the atmosphere. This also removes plants that act as a natural filter for CO2 in the atmosphere, limiting the possibility of a natural recovery.
Therefore, we can confirm that People have concerns about the use of slash and burn because it creates more CO2 and decreases the natural ability to remove it from the air.

for the reaction to reach 38.3 percent completion.
The time taken for the second order reaction is 1494 seconds.
What is a second order reaction?A second order reaction is one in which a plot of the inverse of the concentration of a reactant versus time is a straight line and gives the slope of k which is the rate constant.
The formula for a second order reaction is;
1/[A] = kt + 1/[A]o
[A]o = 0.100 M
[A] = 0.100 M - (0.383 × 0.100 M) = 0.0617 M
k = 4.15 x 10^-3
t = ?
t = (0.0617 M)^-1 - ( 0.100 M)^-1/4.15 x 10^-3
t = 16.2 - 10/4.15 x 10^-3

Copper can have improved wear resistance if alloyed with ceramic alumina, Al2O3. If a copper alloy has 7.7 wt % Al2O3, what is its composition in mol %?
The composition in mol% of the elements are :
4.91% of Al₂O₃ in alloy 95.08% of Cu in alloyGiven data :
Weight percentage of copper alloy = 7.7 wt %
Assume weight of alloy = 100 grams
Applying the weight percentagemass of Al₂O₃ in alloy = 7.7 gm
Mass of Cu in alloy = 100 - 7.7 = 92.3 gm
First step : calculate the mole of elements
i) moles of Al₂O₃ in alloy
= mass of Al₂O₃ in alloy / Atomic mass of Al₂O₃
= 7.7 gm / 102 gm/mol
= 0.075 mol
ii) moles of Cu in alloy
= mass of Cu in alloy / Atomic mass of Cu
= 92.3 gm / 63.5 gm/mol
= 1.45 mol
Therefore the total number of moles in the alloy = 0.075 + 1.45 = 1.525
Next step : Determine the mole percentages
i) Mole percentage of Al₂O₃ in alloy
= ( 0.075 ) / 1.525 * 100
= 4.91%
ii) Mole percentage of Cu in alloy
= ( 1.45 ) / 1.525 * 100
= 95.08%
Hence we can conclude that The composition in mol% of the elements are : 4.91% of Al₂O₃ in alloy and 95.08% of Cu in alloy.

Answer:
Easy question to answer, you have the concentration and volume of the base and you have the volume of the acid. You need to find the concentration of the acid. C1V1 = C2V2 equation can be used here
Explanation:
Volume of NaOH = 0.0681 L (change mL into L)
Concentration or Molarity of NaOH = 0.143 mol/L
Volume of HCl = 0.025 L (change mL into L)
Concentration or Molarity of HCl = ???
C1V1 = C2V2
Rearrange equation to find C2
(C1 * V1) / V2 = C2
(0.143 * 0.0681) / (0.025)
C2 = 0.389532
Concentration or Molarity of HCl = 0.389 mol/L
