A. 128 B. 177 C. 199 D. 120 E. 150
D. 120
Let the length of the train be x meters and its speed be y m/sec. They, x / y = 11 => y = x/11 x + 120 / 22 = x / 11 x = 120 m. Answer:D

What's it called when the reaction is sped up until equilibrium is established? A. division B. favoring C. limiting D. pushing
B. favoring
If more NH 3 were added, the reverse reaction would be favored. This “favoring” of a reaction means temporarily speeding up the reaction in that direction until equilibrium is reestablished. Recall that once equilibrium is reestablished, the rates of the forward and reverse reactions are again equal. The addition of NH...

When Earth first formed, it was a fiery hot, barren ball. It had no oceans or atmosphere. Rivers of melted rock flowed over its surface. Gradually, the planet cooled and formed a solid crust. Gases from volcanoes formed an atmosphere, although it contained only a trace of oxygen. As the planet continued to cool, clouds...
