Predict whether a precipitation reaction will occur in the following situations. If a precipitation reaction occurs, enter the balanced chemical equation for the reaction. NiCl2(aq)+(NH4)2S(aq)→ AgNO3(aq)+CaBr2(aq)→
The density of air at STP is 1.29g/L. If your stoppered the250mL flask contains 242mL of water(also the volume of air it would contain), calculate the mass of air in the flask under STP.
If liquid is at or above it's flash point, the flame spread rate is fast, and the entire pool is engulfed within seconds. In such a case, the liquid is already evaporating sufficiently to reach the lower flammability lim ...
