When observing a group of children at a daycare center, emily made the following observations: five year old children played in one location during independent play time. three year old children moved between different activities, rather than staying in one location. by analyzing emily’s observations, what could be a valid conclusion? a. five-year-old children have longer attention spans than three-year-old children. b. three year old children do not like being in daycare. c. five-year-old children are favored over three-year-old children at the daycare center. d. three-year-old children are favored over five-year-old children at the daycare center.

a. Five-year-old children have longer attention spans than three-year-old children.

Explanation:

The text shown in the question says that five-year-olds remained in the same game for as long as the game lasted. This is because five-year-olds can better understand what is happening around them, so they can focus more on one activity and devote their time to it. On the other hand, the text shows that three-year-olds do not behave the same as five-year-olds, because they cannot stay in one activity for a long time and keep playing games all the time.  This is because three-year-olds do not quite understand what is happening around them and therefore cannot concentrate easily.

With this we can conclude that five year olds have longer attention span than three year olds

a. Five-year-old children have longer attention spans than three-year-old children.

Explanation:

Attention span is the length of time a human brain is able to concentrate on one single activity and not get distracted or suffer mental fatigue. Five year old children have a more mature brain than three year old children. Five year old children have brains that are able to make more neural connections hence they have a prolonged attention span as compared to three old children.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
