An ionic compound and a covalent compound are dissolved in separate beakers of H2O. Which solution will conduct an electric current?

Answer: The empirical formula is [tex]C_{17}H_{19}O_3N[/tex]

Explanation:

Mass of C= 17.900 g

Mass of H = 1.680 g

Mass of O = 4.225 g

Mass of N = 1.228 g

Step 1 : convert given masses into moles.

Moles of C =[tex]\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{17.990g}{12g/mole}=1.5moles[/tex]

Moles of H =[tex]\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{1.680g}{1g/mole}=1.680moles[/tex]

Moles of O =[tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{4.225g}{16g/mole}=0.264moles[/tex]

Moles of N =[tex]\frac{\text{ given mass of N}}{\text{ molar mass of N}}= \frac{1.228g}{14g/mole}=0.087moles[/tex]

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = [tex]\frac{1.5}{0.087}=17[/tex]

For H = [tex]\frac{1.680}{0.087}=19[/tex]

For O =[tex]\frac{0.264}{0.087}=3[/tex]

For N = [tex]\frac{0.087}{0.087}=1[/tex]

The ratio of C : H: O: N = 17: 19: 3: 1

Hence the empirical formula is [tex]C_{17}H_{19}O_3N[/tex]

Explanation:

The percentage by mass of oxygen is defined as;

Mass of oxygen/ molar mass of the compound * 100/1

The average percentage by mass of oxygen = 38.933 + 38.940 + 38.871 + 38.892 + 38.900/5

The average percentage by mass of oxygen = 38.907

Percentage Error  = (|accepted value – experimental value| \ accepted value) x 100%

Percentage Error  = 39.13 - 38.907 / 39.13 * 100

Percentage Error  = 0.57%

Answer:

B. Camels’ ears are lined with fur to keep out sand and other blowing matter.

The coriolis effect is responsible for many large scale weather patterns. The coriolis force is responsible for the deflection of objects. It is this effect which drive the global wind and ocean circulation patterns. The correct option is C.

The apparent effect produced by a rotating frame of reference is defined as the coriolis effect. This effect occurs when an object moving along a straight path is viewed from a non-fixed frame of reference.

Because of the earth's rotation, when an object moving in a straight path is viewed from earth, it appears to lose its course. So the travelling long distances around the earth appear to move at a curve instead of a straight line due to coriolis effect.

The coriolis effect is found to be strongest near poles and it is absent at the equator. The coriolis force is an apparent force caused by the rotation of earth.

Thus the correct option is C.

Explanation:

What would you expect to find?

- The masses of the reactants would be equal to the masses of the product.

Why?

- This is due to the law of conservation of matter which states that matter is neither created nor destroyed in an isolated system but converted from one form to the other.

How is this related to balancing your equations?

- This is why during balancing of equations, we must ensure that the number of atoms in the reactant side must be equal to the number of atoms in the product side.

Explanation:

Heat transfer by radiation tends to be minimal in many everyday instances. This is in part, due to the 4th power exponentiation of the heat transfer equation that governs radiative heat transfer.

For instance, a bar of metal of 75 ºF will interact with your body, from a distance, when your body is at 98 ºF. But the temperature difference of 14 ºF will be so low, that it is difficult to feel or detect. However, if that bar was heated to 120º F and set close to you, you may begin to feel the heat from radiation. Then, if the bar was heated to the point that it began to glow red, several hundred degrees, not only would you feel it, but it may make you uncomfortably hot very quickly. If it was then heated to being white hot, you would almost certainly be burned by it, not by touching it, but simply by the radiative heat transfer. Again, its the 4th power exponent that really makes radiative heat transfer a powerful force when the temperature increases to a high level.

Another example from a text that I once used set an example of a person in a room with their body temperature at 98 ºF. In one case, the walls of the room surrounding the body are said to be 50º F, but in the other case, the walls are said to be 100º F. In both cases, the air in the room is said to be 75ºF. The question is asked: why is the person colder in the room with 50 ºF walls, when the air is the same temperature in both cases.

The answer is that the 100 ºF walls are acting to slightly warm the body, whereas the 50º F walls are actually taking heat away from the body by way of radiative heat transfer. You can do the equations to see exactly how much the different temperatures of the walls will effect this situation.

One final example - if you look into a thermos, you will see a highly reflective liner inside of the thermos. This is a radiant barrier, and it is put into the thermos to keep the liquid inside from losing heat by way of radiation. The reflective film will transfer back most of the heat that would otherwise be lost by radiating to the outer surface of the thermos, after which it would conduct through the side of the thermos. So a thermos provides a good example of a solution for heat transfer in the form of radiation.

Answer:

Ionic Substance is....

Explanation:

In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.

Explanation:

The relationship between H+ and OH-  at 25 °C is given as;

[H+}  x  [OH-]  = 1.0 x 10-14 M

a. 1.0 x 10-5 M OH-

[OH-] = 1.0 x 10-5 M

[H+] = 1.0 x 10-14 M / [OH-] = 1.0 x 10-14 M  / 1.0 x 10-5 M

[H+] = 1.0 x 10^(-14+5)

[H+] = 1.0 x 10^(-9)

pH = - log [H+]

pH = - log [10^(-9)]

pH = 9

This is a basic solution

b. 1.0 x 10-7 M OH-

[OH-] = 1.0 x 10-7 M

[H+] = 1.0 x 10-14 M / [OH-] = 1.0 x 10-14 M  / 1.0 x 10-7 M

[H+] = 1.0 x 10^(-14+7)

[H+] = 1.0 x 10^(-7)

This is a neutral solution since [H+] and [OH-] are equal

c. 10.0 M H+

[H+] = 1.0 x 10 M

[OH-] = 1.0 x 10-14 M / [H+] = 1.0 x 10-14 M  / 1.0 x 10 M

[OH-] = 1.0 x 10^(-14-1)

[OH-] = 1.0 x 10^(-15)

pH = - log [H+]

pH = - log [10^(1)]

pH = -1

This is an acidic solution since it has a pH of -1

Answer:

The correct answer is - yes, 4.57 g of solute per 100 ml of solution

Explanation:

The correct answer is yes we can calculate the solubility of X in the water at 22.0°C. The salt will remain after the evaporate from the dissolved and cooled down at 26°C.

Then, the amount of solute dissolved in the 700 ml solution at 26°C is the weighed precipitate: 0.032 kg = 32 g.

Then solublity will be :

32. g solute / 700 ml solution = y / 100 ml solution

⇒ y = 32. g solute × 100 ml solution / 700 ml solution = 4.57 g.

Thus, the answer is 4.57 g of solute per 100 ml of solution.
