A 100.0 mL sample of 0.200 M HCl is mixed with a 100.0 mL sample of 0.205 M NaOH in a coffee cup calorimeter. If both solutions

were initially at 25.0 C and the temperature of the resulting solution was recorded as 27.0 C, determine the delta Hrxn (in kJ/mol). Assume no heat is lost to the calorimeter. Hint: What is the limiting reagent?

At what temp will a gas be at if you allow it to expand from an original 456 mL to 65°C to 3.4 L
alexira [117]
We use the gas law named Charle's law for the calculation of the second temperature. The law states that,
                                          V₁T₂ = V₂T₁
Substituting the known values,
                                (0.456 L)(65 + 273.15) = (3.4 L)(T₁)
                                             T₁ = 45.33 K

The atomic mass and abundance of Cr-50 is 49.946 amu and 4.3%. The atomic mass and abundance of Cr-52 is 51.941 amu and 83.8%. T
Sati [7]
Multiply the mass by the abundance and add each. Make sure to convert the percentage into a decimal. (49.946 * .043) + (51.941 * .838) + (52.941 * .095) + (53.939 * .024) = 51.99 round up using sig figs and the answer is c. 52.00 amu
