Calculate the percent yield for the reaction:
P4 (s) + 6 Cl2(g) → 4 PC13 (1)

if 75,0 g of phosphorus reacts with excess chlorine gas to produce 111.0 g of phosphorus trichloride.

Select the correct answer. you have a nightlight plugged into an outlet in the hallway, which uses 3.5 watts when plugged in. if the house circuit provides 120.0 volts, what is the current through this bulb?

What does the process of natural selection involve

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
