A buffer solution consists of moderately high concentrations of an acid and its conjugate base. An example is a solution containing 0.1M carbonic acid # (H_2CO_3)# and 0.1M bicarbonate ion # …

This equation can be used to calculate the pH of a buffer solution, which, as you know, contains a weak acid and its conjugate base or a weak base and its conjugate acid in comparable amounts.

Why has Earth's human carrying capacity increased greatly? Consider a stable frog population living at carrying capacity in a pond. If an average female produces 6,000 eggs during her lifetime and an …

Here's one recipe. > It makes 1 L of 0.010 mol/L phosphate buffer of pH 7.2 with ionic strength 0.154 mol/L. The ingredients 0.39 g (0.0028 mol) of "NaH"_2"PO"_4·"H"_2"O" 1.93 g (0.0072 mol) of …

Aug 3, 2016 · Here's what I got. The idea here is that the heat given off by your reaction will be absorbed by the calorimeter. -q_"given off" = q_"absorbed" The minus sign is used here because …

-"1410 kJ/mol" Start by making sure that you have clear understanding of what heat capacity means. As you can se from the units used to express it, heat capacity tells you what the ratio between the …

I need to prepare 100.0mL of a 0.200M acetate buffer of pH 5.00. All I am given is solid sodium acetate and 1.00M of acetic acid. What is the volume of acetic acid used and the mass of sodium acetate …

Feb 27, 2016 · Yes, you use the formula for a cone volume to find the capacity. depth = sqrt147 ~~12.1cm capacity ~~622 cm^3 C = 2*pi*r " and "V = 1/3 * pi * r_2^2* h Diameter = 28 cm , rarr r_1 = …

You'd release 409 J when converting that much mercury from liquid to solid at its melting point. There are two steps to bringing the mercury from liquid to solid at melting point - you must first get the …

However, you included the enthalpy change of the entire system, and you weren't given the heat capacity of sodium, so the way above may be the most effective way given that data on an exam.
