select the equations that are correctly balanced. h2o 2o2? h2o2 fe2o3 3h2? 2fe 3h2o al 3br2? albr3 caco3? cao co2 can you clarif
natta225 [31]
<span>The choices are as follows:
h2o + 2o2 = h2o2
 fe2o3 + 3h2 = 2fe + 3h2o
al + 3br2 = albr3
caco3 = </span><span>cao + co2

The correct answers would be the second and the last option. The equations that are correctly balanced are:

</span> fe2o3 + 3h2 = 2fe + 3h2o 
caco3 = cao + co2

To balance, it should be that the number of atoms of each element in the reactant and the product side is equal.

What can natural selection accomplish? prove Darwin's idea of "survival of the fittest" change relative number of inhabitants wi
oksian1 [2.3K]
Natural selection makes it so that an organism from a species has a better chance of surviving than an organism in the same species, but with different traits. Survival of the fittest proves that certain traits can help an organisms survive better than its peers. For example, say there was an allele that made bears have thicker fur than others. The year-round climate is extremely cold. The bears with thicker fur are more likely to survive due to the warmth their fur provides and will have more offspring. The bears with thinner fur will die more often and not produce healthy offspring due to the frigid temperature. Eventually, the allele for thin fur will die out because the bears with these alleles cannot survive in their habitat.
