Homework Statement This is for a lab. I have two values that I need to subtract, so I am pretty sure I am supposed to add up uncertainty. I have also been told that the uncertainty decimal places should match up with the decimal places on the value itself. 50.00mL ± 0.05mL – 14.3mL ± 0.1mL =...

The purpose was to determine the Ksp of calcium hydroxide using titration calculations

Homework Statement A sample of saturated Ca(OH)2 solution in water is collected in flask #1, filtered into flask #2, then 25.00mL samples were transferred into flasks #3, #4, #5. Which flasks had to be dry and which could be wet? Also, flask #2 was stoppered. Why? Homework EquationsThe...

Thank you, but why is Bromothymol Blue an acid even though it is blue?

Homework Statement Bromothymol blue is an acid-base indicator. When in solution, it forms the following equilibrium: HInd(aq) ⇌ H+(aq) + Ind-(aq) What side of the equilibrium is favored while the solution is in the bromothymol blue bottle?Homework Equations Keq = [(C)c(D)d]/[(A)a(B)b] The...

Ah, so the acceleration decreases until it reaches its terminal velocity.

Thanks, I understand now. What about the downward part of the ball's path? Would acceleration increase?

Homework Statement A ball is thrown vertically upward with an initial speed of v0. It experiences a force of air resistance. The positive direction for all vector quantities is upward. Does the magnitude of the acceleration of the ball increase, decrease, or remain the same as the ball moves...
