Answer:
The velocity is zero
The interpretation of a position-time graph is required.
The correct option is The velocity is zero.
In a position time graph the y axis denotes the position and x axis denotes the time.
A horizontal line where [tex]y\neq 0[/tex].
This means that the points of the line will be for some value of x, the y value will always be constant.
The slope of a position-time graph will gives the velocity of the object.
Slope is given by
[tex]m=\dfrac{\Delta y}{\Delta x}[/tex]
Here, since the graph is a horizontal line, [tex]\Delta y=0[/tex]
[tex]\Rightarrow m=\dfrac{0}{\Delta x}=0[/tex]
The velocity of the person will be zero.

Based on the data given, the correct rate law of the sample reaction is: C. [tex]R = K[A]^2[B]^1[C]^0[/tex]
What is the rate law?Rate law can be defined as a chemical equation that is typically used to relate the initial (forward) chemical reaction rate with respect to the concentrations or pressures of the chemical reactants and constant parameters.
Mathematically, the rate law is given by this formula:
[tex]R = K[A]^x[B]^y[C]^z[/tex]
Where:
k is the rate constant.A is the concentration of reactant A.B is the concentration of reactant B.C is the concentration of reactant C.x, y, and z are the order of the reaction.Based on the data given, the correct rate law of the sample reaction is as follows:
[tex]R = K[A]^2[B]^1[C]^0[/tex]

Explanation:
Two reactant particles collide with proper orientation. The collision will be effective if the particles have
(A) sufficient potential energy
(B) high activation energy
(C) high ionization energy
(D) sufficient kinetic energy
And explain why, and answer in brainly
The collision will be effective if the particles have sufficient kinetic energy (Option D).
Kinetic energy is motion energy, conversely to potential energy.Kinetic energy is required to produce the collision between particles.The more kinetic energy the particles have, then the more collision will occur, thereby it increases the rate of a chemical reaction.In conclusion, the collision will be effective if the particles have sufficient kinetic energy (Option D).

Lithium arsenate (Li3AsO4) and iron nitrate (Fe(NO3)3) are dissolved in water. What precipitate would you expect to form? what is the name and formula?
Answer:
CO₃²⁻ + H₂O <----------------> HCO₃⁻ + OH⁻The chemical formula of the precipitate is Fe(OH)₃Explanation:
Fe(NO₃)₃ and K₂CO₃ are strong electrolytes and completely dissociate in water. Carbonate ions is a weak base and combine with water to form hydroxide ions (OH⁻), CO₃²⁻ + H₂O <----------------> HCO₃⁻ + OH⁻ Ferric, Fe (III), combines with these hydroxide ions to form insoluble precipitates. Fe(OH)₃ is only partially soluble i.e., it does not completely dissociate in water. When the solutions of Fe(NO₃)₃ and K₂CO₃ are mixed, Fe(OH)₃ precipitates out due to the strong electrostatic attraction between Fe (III) and hydroxide ions.Convert 9.213 moles of fe to grams

Answer:
Is a nonrenewable resource
Explanation:
"The fuel for fusion reactors can be drawn from sea water in an almost unlimited supply. The fuel for fission, on the other hand, comes from a limited supply of uranium. Once it is depleted, it cannot be easily replenished. For this reason, nuclear power is considered a nonrenewable resource."

Zinc metal reacts with aqueous copper(II) chloride, as shown in this equation. If 3.03 x 1021 atoms of zinc react, how many grams of Cu will form? Show the sequence of conversions necessary, then calculate the numerical answer. Zn (s) + CuCl2 (aq) ---> ZnCl2 (aq) + Cu (s)
Answer:
0.320 g Cu.
Explanation:
Hello there!
In this case, case, according to the presented chemical reaction, it is possible to determine that the mole ratio of zinc to copper is 1:1 and therefore, we will have the same amount of atoms for the both of them. Moreover, since one mole of copper contains 6.022x10²³ atoms of this element, with a mass of 63.546 g (molar mass); it is possible for us to write up the following mathematical setup in order to calculate the produced grams of copper:
[tex]3.03x10^{21}atoms Zn*\frac{1atom Cu}{1atom Zn}*\frac{1molCu}{6.022x10^{23}atoms Cu}*\frac{63.546gCu}{1molCu} \\[/tex]
Thus, the numerical result turns out to be:
0.320 g Cu

1. The pH of a solution made by combining 150.0 mL of 0.10 M KOH with 50.0 mL of 0.20 M HBr is closest to which of the following?
Answer:
12
Explanation:
The pH of the solution prepared has been 1.25.
The pH of the solution resulting from the mixing of the two solutions can be given by:
Hydrogen ion concentration = [tex]\rm \dfrac{M_1V_1\;-\;M_2V_2}{V_1\;+\;V_2}[/tex]
Where, M1 and M2 have been the molarity of the solution and V1 and V2 have been the volume of the solutions.
For the given resulted solution:
Hydrogen ion concentration = [tex]\rm \dfrac{0.1\;\times\;0.15L\;-\;0.2\;\times\;0.05L}{0.15\;+\;0.05\;L}[/tex]
Hydrogen ion concentration = 0.055 M
pH can be defined as the negative logarithm of hydrogen ion concentration.
pH = - log (Hydrogen ion concentration)
pH = -log (0.055)
pH = 1.25
The pH of the solution prepared has been 1.25.
