Your teacher asks you to follow the instructions in a lab to produce several known chemical reactions. During these procedures,
you are required to record any observations that suggest chemical reactions have occurred. Which of these list of observations best
describes evidence of chemical reactions?
a. a liquid melts and becomes a solid.
b. when heated steam comes out of a test tube.
c. a gas or solid is formed from two liquid solutions.
d. the two chemicals separate and form two distinct layers.

What is limiting reactant? with examples

In a spacecraft, the following reaction occurs: co2(g) + 2lioh(s) -> lico3(s) + h2o(i) (i attached picture of equation) how many liters of carbon dioxide will 4 moles of lithium hydroxide (lioh) absorb? (one mole of any gads occupies 22.4 l under certain conditions of temperature and pressure. assume those conditions for this equation.) 45l 6.0l 3.0l 34l

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
