Write the balance chemical equation for propane.

What must be changed, temperature or heat energy, during condensation explain in 2-3 sentences

Nastasia [14]

Answer:

Change occur in heat energy.

Explanation:

Change occur in the heat energy of molecules during condensation process. The molecules of gas releases its heat energy and converted into liquid state. With this heat energy, they are active and escape from each other but when the heat energy is removed from them, the attractive forces between these gas molecules are formed which convert them into liquid state so change in heat energy occur in the condensation process.

Calculate the ratio of naf to hf required to create a buffer with ph = 4.05.

NARA [144]

PH is the test of acidity or basicity of a solution. it follows the formula:
pH = pKa + log [salt] / [acid] where NaF is the salt and HF is the acid in this case.

By literature, Ka of HF is 3.5*10^-4
pKa= -log(Ka)= 3.46 

pH = pKa + log [NaF / [HF] 

4.05 = 3.46 + log [NaF / [HF]

log [NaF / [HF] = 0.59

[NaF / [HF] = 3.89
