1. a compound is when the atoms of different elements are chemically held to one another. a mixture is a substance that has two or more different materials in such a way that no chemical reaction occurs.
A mixture can usually be separated back into its original components, a compound can not.
Example of mixture: salt water, because you can evaporate the water and get the salt. it is not chemically held together.

Example of a compound: H2O(water) you cant seperate the hydrogen and oxygen


2. the size of the sugar particles are probably extremely small because it is dissolved

3. the ice cubes are bigger. if you want to remove the sugar, you would have to evaporate the water.

What is the frequency of radiation whose wavelength is 2.51 x 10 -7m?​
hodyreva [135]

The frequency of radiation : 1.2 x 10¹⁵ Hz

<h3>Further explanation </h3>

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

\large{\boxed{\bold{E\:=\:h\:.\:f}}}

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

<h3>f = c / λ </h3>

c = speed of light

= 3.10⁸  m/s

λ = wavelength

Wavelength-λ is 2.51 x 10⁻⁷m

The frequency :

\tt f=\dfrac{3.10^8}{2.51\times 10^{-7}}=1.2\times 10^{15}

Suppose 6 quarts of a solution that is 45% antifreeze is mixed with 2 quarts of a solution that is 19% antifreeze.
Sidana [21]
6+2=8 quarts of a new solution

0.45*6  - quarts  antifreeze in <span>a solution that is 45% antifreeze
0.19*2  - </span>quarts  antifreeze in a solution that is 19% antifreeze

x- concentration of a new solution
8x -  quarts  antifreeze in a new solution 

0.45*6 + 0.19*2 = 8x
3.08=8x
x= 0.385 =38.5 %
