Constants Periodic Table Imagine that you are in chemistry lab and need to make 1.00 L of a solution with a pH of 2.80. Part A You have in front of you 100 mL of 7.00x10-2 MHCI, 100 mL of 5.00x10-2 MNaOH, and plenty of distilled water. Assuming the final solution will be diluted to 1.00 L , how much more HCl should you add to achieve the desired pH? Express your answer to three significant figures and include the...

Chemists often use molarity MM, in moles/litermoles/liter, to
measure the concentration of solutions. Molarity is a common unit
of concentration because the volume of a liquid is very easy to
measure. However, the drawback of using molarity is that volume is
a temperature-dependent quantity. As temperature changes, density
changes, which affects volume. Volume markings for most laboratory
glassware are calibrated for room...

Please help solve and show work.
Review Constants Periodic Table The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temperature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. In this problem answers are requested to three significant digits for...

< 9 of 13 Review Constants Periodic Table Part A A calorimeter contains 28.0 mL of water at 11.0 °C. When 250 g of X (a substance with a molar mass of 60.0 g/mol) is added, it dissolves via the reaction X(s) + H2O(1) X(aq) and the temperature of the solution increases to 30.0 °C. Calculate the enthalpy change, AH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that...

ReviewI Constants Periodic Table The air that surrounds us is mostly empty space, and it can be almost a factor of one thousand less dense than water. Within that mostly empty space, gas molecules are moving around at high speed and colliding with each other, and if you are in an enclosed space, they are also colliding with the walls. We can more easily observe the behavior of a gas by confining it to a container with a known volume,...
