Using the balanced equation

2c2h6 +702 --> 4co2 +6h20
if 43 g c2h6 react with 105 g o2, what is the excess reactant?

-c2h6
-co2
-h20
-o2

In which environment would primary succession occur? a forest with a few remaining trees after a recent wildfire an area of exposed rock after a glacier melts away beach that is exposed to the air at low tide an abandoned baseball field in a small town

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
