Well it really depends on what circuit, there's a circuit that means... hmm

ill try to give an example,
You're at a race track, and usually race tracks have the start line, and the finish line, usually they're the same line. So basically where I'm getting at is, it starts where it finishes in circular route; if that made any sense. 

It could also mean simple transportation from one place or another.

A student dissolves powdered tea in water. How can the student separate the parts of the mixture?
mars1129 [50]

Answer:

The student can evaporate the liquid water.

Explanation:

The student only mixed water with the powdered tea. Therefore, if the water is evaporated from the mixture, the student will be left with the tea mixture only.

A wooden boat is discovered just south of the Graet Pyramid in Egypt had a Carbon-14 content of approximately 25% of that found
wolverine [178]

Because 25% is half of 0.5 and the half life of {}^{14}\text{C} is given as 5,715, the time it takes to reach this amount should just be double the half life: 11430 years.

However, in other cases the problem may not have easy numbers, so below is a more mathematical approach.

The half life formula is A=A_0*(\frac{1}{2} )^{\frac{t}{h} }.

Solving for t gives:

t=\frac{h*\ln(\frac{A}{A_0} )}{\ln(\frac{1}{2} )}

Given information:

A=0.25A_0\\h=5715\text{ yrs}

Plug in given values and solve for t.

t=\frac{5715 *\ln(0.25) }{\ln(\frac{1}{2} )} =11430 \text{ yrs}

With correct significant figures, this would be 11000 years.

How many isomers are there with the formula c3h4? include both structural and geometric isomers?
sleet_krkn [62]
There are three possible Isomers for Molecular Formula C₃H₄. Isomers are;

                                           1) Propyne

                                           2) Propa-1,2-diene

                                           3) Cyclopropene

Structures of all three isomers are given below.

There are no geometrical isomers for given molecular formula because geometrical isomers are formed in compounds containing double bond with at least two bulky groups at both sp² hybridized carbons. In given isomers, propyne does not contain any double bond, Propa-1,2-diene is symmetrical in nature while cyclopropene is a 3-membered ring. And for cycloalkenes there must be other groups attached to ring other than Hydrogen atom, hence cyclopropene does not contain any other group, so it can not show geometrical isomerism.

1.72 moles of NOCI were placed in a 2.50 L reaction chamber
elena-14-01-66 [18.8K]

The equilibrium constant, Kc=0.026

<h3>Further explanation</h3>

Given

1.72 moles of NOCI

1.16 moles of NOCI  remained

2.50 L reaction chamber

Reaction

2NOCI(g) = 2NO(g) + Cl2(g).

Required

the equilibrium constant, Kc

Solution

ICE method

   2NOCI(g) = 2NO(g) + Cl2(g).

I    1.72

C   0.56           0.56         0.28

E   1.16              0.56         0.28

Molarity at equilibrium :

NOCl :

\tt \dfrac{1.16}{2.5}=0.464

NO :

\tt \dfrac{0.56}{2.5}=0.224

Cl2 :

\tt \dfrac{0.28}{2.5}=0.112

\tt Kc=\dfrac{[NO]^2[Cl_2]}{[NOCl]^2}\\\\Kc=\dfrac{0.224^2\times 0.112}{0.464^2}=0.026
