4. Ethanol has a specific heat of 2.44 (J/g.°C). The temperature of 34.4 g of ethanol increases
from 25 °C to 78.8 °C. How much Heat was absorbed?

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.

What is the approximate vapor pressure when the gas condenses at 70 degrees celsius
