Jaime measures the density of a slab of aluminum (al) metal. what information does jaime need to evaluate the accuracy of his measurement? the accepted value for the density of aluminumthe dimensions of the slab of aluminum that he useda bar graph that shows the densities of different slabs of aluminuma line graph that shows how the density of aluminum varies with temperature

The accepted value for the density of aluminum

Explanation: Accuracy is defined as the degree to which the result of a measurement conforms to the correct value or a standard value.

In order to evaluate the accuracy of his measurement he should relate it to the standard value of density.

Density is a characteristic property of a substance and remains fixed for a particular substance.

Dimensions of the slab would only give the volume of aluminium metal.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
