For a particular amount of gas at a constant temperature, the pressure is 3.00 atm at a volume of 80.0 mL. What would the pressure be if the volume is changed to 140.0 mL? Enter your answer as a decimal number.
At 200°C, in the reaction below, the molar concentration of A was 7.81 M after 2.33 s and 1.45 M after 7.93 s. What is the average rate of reaction in M/s? 2A => Q + Z
Two identical rubber bands, A and B, are each 10cm long when relaxed. They are looped together to yield a combined length of 20cm. This length is then stretched to 50 cm. If A is at 25 degrees celcius and B is at 100 degrees celcius, where, is rel..
If you have 100 ml of pure water and add to it 10 ml of 2.0M HNO3, what will be the pH of the final solution
Question- Many gases are produced through chemical reactions inside closed systems in a research lab because only a small amount of the gas is required as a reagent for a further chemical reaction.
A solution containing 100.0 mL of 0.135 M CH3COOH (ka=1.8E-5) is being titrated with 0.54 M NaOH. calculate the ph: at the equivalence point and 5 mL past the equivalence point.
Consider a solution formed by mixing 30.0 mL of 0.100 M H2SO4, 24.5 mL of 0.100 M HOCl, 25.0 mL of 0.200 M NaOH, 25.0 mL of 0.100 M Ca(OH)2, and 10.0 mL of 0.150 M KOH. Calculate the pH of this solution.
