How much energy is required to completely vaporize 250 grams of liquid water that is already at 100 degrees Celsius? Show your work & units. Expected Answer = 565,000 J

564100J (~ 565000J) of heat energy is required.

Explanation:

The enthalpy of vaporization of water is 2256.4J/g, meaning that 2256.4J of heat is required to convert 1 gram of water at 100 degrees Celcius to steam at 100 degrees Celcius.

In your case, we have 250g of water at 100C and we want to vaporize it to steam (also at 100C).

This requires ΔH = 2256.4(250) = 564100J of heat energy.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
