Answer:

15%

Explanation:

From the question given above, the following data were obtained:

Mass of sugar = 15 g

Mass of water = 85 g

Percentage of sugar in the solution =?

Next, we shall determine the mass of the solution. This can be obtained as follow:

Mass of solute (sugar) = 15 g

Mass of solvent (water) = 85 g

Mass of solution =?

Mass of solution = mass of solute + mass of solvent

Mass of solution = 15 + 85

Mass of solution = 100 g

Finally, we shall determine the percentage of the sugar in the solution. This can be obtained as follow:

Mass of solute (sugar) = 15 g

Mass of solution = 100 g

Percentage of sugar in the solution =?

Percentage = solute /solution × 100

Percentage = 15 / 100 × 100

Percentage of sugar in the solution = 15%

Because oxygen is more electronegative than hydrogen, the water molecule is

lapo4ka [179]

The water molecule has two hydrogen atoms joined to one oxygen atom by single covalent bonds. Because oxygen is more electronegative than hydrogen, the electrons of the covalent bond spend more time closer to the oxygen then hydrogen which creates a polar covalent bond. Hope this answers your question. Have a great day!

A chemist is using radiation with a frequency of 6.0 x 10^13 Hz

kirza4 [7]

Answer:

λ = 0.5×10⁻⁵ m

E = 39.78×10⁻²¹ J

The given radiation is gamma ray.

Explanation:

Given data:

Frequency of radiation = 6.0 ×10¹³ Hz

Wavelength of radiation = ?

Type of radiation = ?

Energy of radiation = ?

Solution:

Formula:

speed of light = wavelength × frequency

3 ×10⁸ m/s = λ × 6.0 ×10¹³ Hz

Hz = s⁻¹

λ = 3 ×10⁸ m/s / 6.0 ×10¹³ s⁻¹

λ = 0.5×10⁻⁵ m

Energy of radiation:

E = hf

h = planck's constant

f = frequency

E = 6.63×10⁻³⁴ j.s × 6.0 ×10¹³ s⁻¹

E = 39.78×10⁻²¹ J

The given radiation is gamma ray.

What will happen if a crystal of ammonium nitrate is added to a supersaturated ammonium nitrate solution? Will it dissolve in wa

romanna [79]

Answer:

It will not dissolve. More crystals will separate from the solution.

Step-by-step explanation:

If you add a crystal of ammonium nitrate to a supersaturated solution of the solute, it will not dissolve.

Instead, it will act as a "seed" on which more ammonium nitrate crystals will form.

They will separate from the solution as long, colourless, needle-like crystals until the solution is no longer supersaturated.

A solution has a pH of 11.8. What is the pOH?

amid [387]

Answer:

pOH is 2.2

Explanation:

The pH scale goes from 0 to 14. As such, the pH and the pOH add up to 14. Subtract your pH from 14 to get your answer.

14 - 11.8 = 2.2
