Explanation:

The sample has halved twice.

1/2 of 1/2 is 1/4, and 1/2 of 1 is 1/2.

From the options listed The graph would show a negative correlation  ( C )

Correlation is used to express the relationship between two or more variables.  correlation can be measured into four ( 4 ) in statistics :

But Generally correlation is categorized as either a positive or a negative correlation.

In a negative correlation the variables are inversely proportional to each other while in a positive correlation the variables are directly proportional to each other.

Note : an inverse proportion simply means that an increase in value of one variable = decrease in value of the other and vice versa

hence the graph would show a negative correlation given that the the values of the motorcycle decreases with increase in time.

Answer: 4.4lb

Explanation:

Answer:

Kc =[tex]\frac{[8.326x10-3]^{1} }{[1.113x10-2]^{1}[1.490x10-2]^{1} }[/tex]

Kc = 50.2059

Explanation:

1. Balance the equation

2. Use the Kc formula

Remember that pure substances, like H2 are not included on the Kc formula

The value of the equilibrium constant Kc of the reaction at the temperature of the vessel is 0.05.

Calculation,

The balanced chemical equation is given as,

                      [tex]2H_{2}O[/tex]             +         [tex]2CO[/tex]            →            [tex]2H_{2}[/tex]       +     [tex]2CO_{2}[/tex]

At t=0          1.113×[tex]10^{-2}[/tex]                 1.490×[tex]10^{-2}[/tex]                                         0

At [tex]t=t_{eq}[/tex] 1.113×[tex]10^{-2}[/tex]-8.326×[tex]10^{-3}[/tex]   1.490×[tex]10^{-2}[/tex]-8.326×[tex]10^{-3}[/tex]            8.326×[tex]10^{-3}[/tex]  

The number of moles of [tex]H_{2}O[/tex] at equilibrium  =  1.113×[tex]10^{-2}[/tex]-8.326×[tex]10^{-3}[/tex]

The number of moles of [tex]CO[/tex] at equilibrium  = 1.490×[tex]10^{-2}[/tex]-8.326×[tex]10^{-3}[/tex]

The number of moles of  [tex]CO_{2}[/tex]   at equilibrium =   8.326×[tex]10^{-3}[/tex]  

Equilibrium constant is calculated bt ratio of product of concentration of reactant by product.

K = [tex][H_{2}O]^{2}[/tex]×[tex][CO]^{2}[/tex]/[tex][CO_{2}]^{2}[/tex]

K =( 1.113×[tex]10^{-2}[/tex]-8.326×[tex]10^{-3}[/tex] )∧2× (1.490×[tex]10^{-2}[/tex]-8.326×[tex]10^{-3}[/tex])∧2/(8.326×[tex]10^{-3}[/tex])∧2

K = 0.049 ≈ 0.05

The equili constant assuming reaction is from isomer A to isomer B; 19

i.e. A ⇄ B = 19

Given data :

% wt of A = 5

% wt of B = 95

assume the mass of mixture = 100 g

wt of A = 5% of 100 = 5 g

wt of B = 95% of 100 = 95 g

∴ mole of A = 5/M mol,  mole of B = 95/M  mol   ( where M = molar mass )

expressing the equilibrium constant

A ⇄ B  

equilibrium constant = [tex]\frac{[B]}{[A]}[/tex] = [tex]\frac{ (95/M) /V}{(5/M)/V}[/tex]  where V = volume

∴ Equilibrium constant = 19 assuming process is from A to B

hence the equilibrium constant = 19 assuming reaction process is from A to B

Answer:

a. Expansion: the spatial dilation of a material that occurs upon changes in its composition. (an increase in number or amount to become larger in size.)

E.g- in a thermometer, when it gets hotter, the liquid inside them expands and rises up the tube.

b. Sublimation: the process in which a solid changes directly into a liquid.

E.g- dry ice, solid iodine and ammonium salts.

when the above solids are heated, only particles which are found on the surface of the solid have enough energy to break all forces of attraction and form a gas.

c. Contraction: it is the opposite of expansion. when a liquid is cooled the particles slow down and contract.

E.g- when a thermometer is taken out of your mouth, it contracts and the liquid inside falls back to the bottom.

f. Random Motion: motion in which the particle moves in a zig-zag manner and not in a straight line. The kinetic particle theory states that matter is made up of particles which are in constant random motion,

Answer:

in a 1 Liter flask at 850 K, the equilibrium concentration of NH3 is measured as 0.12 M. Given that ammonia decomposes according to the reaction

2 NH3(g) ⇌ N2(g) + 3 H2(g),

what is Kc for the reaction?

a. 0.16

b. 12.00

c. 1.44

d. 6.22

e. 0.75

The response is 12.00 (b). Using the equation Kc = [N2][H2]3/[NH3]2, we can find the equilibrium constant Kc for the reaction 2 NH3(g) N2(g) + 3 H2(g).

In this instance, the capacity of the flask is 1 litre, and the equilibrium concentration of NH3 is 0.12 M. Therefore, using the reaction's stoichiometry, it is possible to determine the equilibrium concentrations of N2 and H2.

Since 2 moles of NH3 break down into 1 mole of N2 and 3 moles of H2, the equilibrium concentrations of N2 and H2 are 0.06 M and 0.18 M, respectively. As a result, the equilibrium constant Kc = [N2][H2]3/[NH3]2 = (0.06)(0.18)3/0.122 = 12.00 may be computed.

Therefore, b. 12.00 is the right response. You should be aware that the equilibrium constant Kc is a value that is temperature-dependent and is only applicable at the specified temperature. As a result, Kc will have a varied value depending on the temperature. The temperature in this instance is 850 K, and the Kc value is 12.00.
