One liter of a phosphate buffer, 0.100 m. ph 7, is required. a) how would this buffer prepared if the reagents available are sodium dihydrogen phosphate (nah2po4 x h2o) and disodium hydrogen phosphate (na2hpo4) present as solids? distilled water is also available. b) how would this buffer be prepared if the reagents available are phosphoric acid (h3po4) and 1.5 m naoh? concentrated phosphoric acid is 15 m. distilled water is also available.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

tobey

if you mean hydrogen and oxygen then water is the product

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
