Fill in the blank to balance the following chemical equation:
2 al + h2so4 --> al2(so4)3 + 3 h2
match each chemical reaction to its type:
c3h8 + 5 o2 --> 3 co2 + 4 h2o
2 h2o2 --> 2 h2o + o2
agno3 + kbr --> agbr + kno3
cucl2 + zn --> zncl2 + cu
cao + h2o --> ca(oh)2
a.
combustion
b.
synthesis
c.
decomposition
d.
single replacement
e.
double replacement
you suspect one of the products of a single replacement is hydrogen gas. how might you experimentally confirm your prediction? choose the best option.
watch for bubbles to form in solution which indicates a gas was produced.
waft to detect an odor from the test tube.
place a burning splint near the end of the test tube and listen for a 'pop' sound.
hydrogen gas is never a product in a chemical reaction.
