When you convert feet to inches, how do you decide which portion of the conversion factor should be in the numerator and which i
Inessa05 [86]

Answer : The conversion used is, 1\text{ feet}=12\text{ inches}

Explanation :

The conversion used :

1\text{ feet}=12\text{ inches}

For example : To convert 10 feet into inches.

1\text{ feet}=12\text{ inches}

10\text{ feet}=10\text{ feet}\times \frac{12\text{ inches}}{1\text{ feet}}

                    =120\text{ inches}

From this we conclude that, the conversion factor used in the numerator and denominator for 1 feet should be, \frac{12\text{ inches}}{1\text{ feet}}

The equilibrium constant, K., for the following reaction is 83.3 at 500 K. PC13(g) + Cl2(g) = PC13(E) Calculate the equilibrium
lord [1]

Answer:

The equilibrium concentration of PCl_5=0.228 M.

The equilibrium concentration of PCl_3=0.280 M -0.228 M=0.052M.

The equilibrium concentration of Cl_2=0.280 M -0.228 M=0.052M.

Explanation:

Answer:

The equilibrium concentration of HCl is 0.01707 M.

Explanation:

Equilibrium constant of the reaction = K_c=83.3

Moles of PCl_3 = 0.280 mol

Concentration of  [PCl_3]=\frac{0.280 mol}{1.00 L}=0.280 M

Moles of Cl_ = 0.280 mol

Concentration of [Cl_2]=\frac{0.280 mol}{1.00 L}=0.280M

           PCl_3(g)+Cl_2(g)\rightleftharpoons PCl_5(g)

Initial:            0.280      0.280                            0

At eq'm:         (0.280-x)   (0.280-x)                     x

We are given:

[PCl_3]_{eq}=(0.280-x)

[Cl_2]_{eq}=(0.280-x)

[PCl_5]_{eq}=x

Calculating for 'x'. we get:

The expression of K_{c} for above reaction follows:

K_c=\frac{[PCl_5]}{[PCl_3][Cl_2]}

Putting values in above equation, we get:

83.3=\frac{x}{(0.280-x)\times (0.280-x)}

On solving this quadratic equation we get:

x = 0.228, 0.344

0.228 M < 0.280 M< 0.344 M

x = 0.228 M

The equilibrium concentration of PCl_5=0.228 M.

The equilibrium concentration of PCl_3=0.280 M -0.228 M=0.052M.

The equilibrium concentration of Cl_2=0.280 M -0.228 M=0.052M.

What is the working of NMR?
tiny-mole [99]

Answer:

NMR stands for Nuclear Magnetic Resonance, and NMR spectroscopy is the technology that makes use of the phenomena of NMR in the analysis of a material's molecular structure through measurement and observance of the nuclear spin interactions, in order to determine the biological, physical and chemical properties of the material

NMR works by the noting that some atoms in molecules placed in a strong magnetic field display the characteristics of small magnets. The application of a broad spectrum radio frequency to the molecules will cause the nuclei to resonate at particular frequencies. An NMR spectrum is formed from the measured nuclei resonant frequencies such that the graph peaks shows the correct frequencies in the sample and the peak height is directly related to the proportion or number of the nuclei which are resonating to a given frequency, such that the frequency values are indicative of the type of atoms and their distances apart from a given atom

There are two reactants
Xelga [282]

Answer:

13g

Explanation:

The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction.

Therefore, if the total mass of the products is 30g, that means that the reactants have a mass of 17g + the other reactant to = 30g.

30g - 17g = 13g
