when young children are learning new words, they
“Interestingly, we observed that even from the time children mature from 18 to 30 months of age, the cues toddlers use to learn new words change.”. In the study, researchers taught six new words to children, who ranged in age from 18 to 36 months, using three types of cues. The cues were presented alone or in pairs, and the researchers recorded the children’s ability to accurately guess what the words meant.
Alkanes and Cycloalkanes Alkanes —molecules consisting of carbons and hydrogens in the following ratio: C n H 2n+2 Therefore, an alkane having 4 carbons would have 2(4) + 2 hydrogens, which equals 10 hydrogens.This molecule would have the general formula C 4 H 10.l Answer Cycloalkanes —consist of rings of —CH 2 units. Cycloalkanes have the formula: C n H 2n Nomenclature To name a molecule as a cycloalkane, the number of carbons in the ring must be greater than the number of carbons in any substituent. The number of carbons in the ring is the parent chain.
