Does sugar when dissolved form ions

Chemistry
2 answers:
sveticcg [70]3 years ago

Answer:

Dissolving sugar is a physical change. It is not a chemical change. So, ions will not be formed.

tatyana61 [14]3 years ago

Explanation:

Sugar will readily dissolve in water but doesn't form cations and anions in solution. That is, there are no charge carriers formed. Substances that only partially ionize into ions when dissolved in water are called weak electrolytes.

I hope it help:)

How many protons, electrons, and neutrons does the following isotope contain? 79Br+
stellarik [79]

The number of protons = atomic number in Periodic table, so 35

The number of neutrons = mass number - number of protons = 79-35=44

The number of electrons = atomic number - 1 = 35-1 =34

Calculate the molarity of the two solutions.
beks73 [17]

Answer:

A = Molarity = 0.22 M

B = Molarity = 0.36 M

Explanation:

Given data:

For first solution:

number of moles = 0.550 mol

Volume of solution = 2.50 L

Molarity = ?

Molarity:

Formula:

Molarity = number of moles of solute / volume of solution in L.

Molarity = 0.550 mol / 2.50 L

Molarity = 0.22 M

For second solution:

Mass of NaCl =  15.7 g

Volume of solution = 709 mL  or 709/1000 = 0.709 L

Molarity = ?

Solution:

Number of moles = mass / molar mass

Number of moles = 14.7 g/ 58.44 g/mol

Number of moles = 0.252 mol

Molarity:

Molarity = number of moles of solute / volume of solution in L.

Molarity = 0.252 mol / 0.709 L

Molarity = 0.36 M

A topaz crystal has an interplanar spacing (d) of 1.36 Å (1 Å =1×10^[−10] m). Calculate the wavelength of the X-ray that should
bija089 [108]

Answer:

7.0*10-11m or 70Å

Explanation:

From Bragg's equation, w=2dsinx/n

Since all the parameters are specified in the question, we can easily go ahead to obtain the wavelength but we must convert the spacing given in angstroms to meters using the conversion factor provided as shown in the solution below:

Compared to visible light, an electromagnetic wave that has a longer wavelength will also have ________.
Anestetic [448]

Question∵

Compared to visible light, an electromagnetic wave that has a longer wavelength will also have?

Answer:

Hi, There! -Randp12- My Name Is jay I'm here to help! :)

<u><em>The correct answer is lower frequency.</em></u>

Explanation:

Information to  Support My Answer :D

it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.

Therefore  for higher wavelength, the electromagnetic wave will also have lower frequency.

Hope this helps!
