Suppose that for the same 10.0 ml sample described in q3, the mass of the crucible with precipitate was 17.550 g, and the mass of the empty crucible (tare weight) was 17.410 g. calculate the concentration of the ba (oh) 2 solution from these data.

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 Kelvin and 1.21 atmospheres? Show all of the work used to solve this problem. 2Li (s) + 2H2O (l) yields 2LiOH (aq) + H2 (g)

A student needs to dilute a 0.46 M Pb (NO3) 2 solution to make 55.0 mL of 0.14 M Pb (NO 3) 2. Set up the calculation by placing the values with the correct units into the equation. Then, calculate the volume, in milliliters, of the 0.

When you kick a soccer ball across a field it will eventually come to a stop. Does this prove or disprove Newton's first law of motion? It disproves Newton's first law of motion because gravity is stronger than friction.
