(Sorry for my bad drawing I don't have the physical official drawing) frosty has been accused of breaking into a house through a

window, moving into the next room, and stealing valuables from a safe. He is also accused of melting as he went from one room to the other and back. Prove that Frosty the Snowman has or has not committed the crime of stealing the money and jewelry from a safe! (Using knowledge on states OF matter: solid, liquid, and gas, melting and freezing points , and vaporization/evaporation. By the way the *F is degrees Fahrenheit .

Frosty the snowman is GUILTY. he broke into a room that was 20 degrees F, then moved into the room with the safe, which was 65 degrees F, above the freezing point, and no snow can not melt at 65 degrees. as he was tromping through the hot house, he began to turn back into liquid because he began melting in the heat. so all evidence points towards the fact that frosty did it.

Frosty the Snowman did break into the house. He did because the melting point of water is 32 degrees Fahrenheit and so he went from a solid to a liquid. There was no other way to answer the question because he did. He must have if the temperature was below freezing point he would remain solid and until the temperature was higher that 32.

What is the ph of a buffer prepared by adding 0.809 mol of the weak acid ha to 0.608 mol of naa in 2.00 l of solution? The disso
Anarel [89]

The pH of the buffer is 6.1236.

Explanation:

The strength of any acid solution can be obtained by determining their pH. Even the buffer solution strength of the weak acid can be determined using pH. As the dissociation constant is given, we can determine the pKa value as the negative log of dissociation constant value.

pKa=-log[H] = - log [ 5.66 * 10^{-7}]\\ \\pka = 7 - log (5.66)=7-0.753=6.247\\\\pka = 6.247

The pH of the buffer can be known as

pH = pK_{a} + log[\frac{[A-]}{[HA]}}]

The concentration of [A^{-}] = Moles of [A]/Total volume = 0.608/2 = 0.304 M\\

Similarly, the concentration of [HA] = \frac{Moles of HA}{Total volume} = \frac{0.809}{2} = 0.404

Then the pH of the buffer will be

pH = 6.247 + log [ 0.304/0.404]

pH = 6.247 + log 0.304 - log 0.404=6.247-0.517+0.3936=6.1236

So, the pH of the buffer is 6.1236.

To make a sarurated solution, 36 g of sodium chloride is dissolved in 100 g of water at 293 k . Find its concentration at this t
nexus9112 [7]

Answer:

The answer is "26.47\%"

Explanation:

Sodium chloride  solute mass=36 \ g

Solvent water mass=100\ g

Calculating the solution mass = Solute mass  + solvent mass

                                                  = 36\ g +100\ g\\\\ = 136\ g\\\\

Calculating the percentage of concentration:

= \frac{solute\ mass}{solvent\ mass} \times 100\\\\=\frac{36\ grm}{136\ grm} \times 100\\\\=0.2647 \times 100\\\\=26.47 \%
