a. If 103 g of ethanol is needed for a chemical reaction, what volume of liquid would you use? The density of ethanol is 0.789 g/mL. b. For the above reaction, to what height (in cm) would you need to fill a graduated cylinder with a 1.1 in diameter?

2. you__turn left on a red light if you are in the left-most lane of a one-way street, you're turning into the left-most lane of a one-way street, and no nearby sign prohibits the turn.

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

Think about how you can use le chatelier’s principle to find possible solutions to the design problem. describe at least two ways to increase the yield (amount) of ammonia based on this principle.
