Why does sugar dissolves easily in water but sand doesn’t

GarryVolchara [31]

Table sugar dissolves in water because when a sucrose molecule breaks from the sugar crystal, it is immediately surrounded by water molecules. The sucrose has hydroxyl groups that have a slight negative charge. ... Sand can't dissolve in waterbecause the 'spaces' in between the water particles. :)

If you were to mix 7 grams of sugar into 100 grams of water, how much should the total mass of the solution be?

inn [45]

Answer:

<em>The total mass of the solution should be 107 grams</em>

Explanation:

<u>Solutions</u>

A solution is a homogeneous mixture consisting of a solute dissolved into a solvent. The solute is the substance that is being dissolved, while the solvent is the dissolving medium.

The relationship between the masses is:

$m_s=m_o+m_v$

Where:

ms = mass of the solution

mo = mass of the solute

mv = mass of the solvent

If you were to mix mo=7 gr of sugar into mv=100 gr of water, then the total mass of the solution should be:

$m_s=7~gr+100~gr$

$m_s=107~gr$

The total mass of the solution should be 107 grams

What is the wavelength of the carrier wave of a campus radio station, broadcasting at a frequency of 97.2 MHz (million cycles pe

andrey2020 [161]

Answer:

Wavelength is 3.08 meters.

Explanation:

It is given that,

Frequency, $f=97.2\ MHz=97.2\times 10^6\ Hz$

We need to find the wavelength of the carrier wave of a campus radio station. It can be calculated by using following relation as :

$c=f\times \lambda$

$\lambda=\dfrac{c}{f}$

$\lambda=\dfrac{3\times 10^8\ m/s}{97.2\times 10^6\ Hz}$

$\lambda=3.08\ m$

So, the wavelength of the carrier wave is 3.08 meters. Hence, this is the required solution.
