The information that should be added to the chart in order to find out who ran a greater distance is THE UNITS USED TO MEASURE DISTANCE EACH DAY.

In science, the use of units if very important and each record made must be accompany with relevant units that are appropriate for the measurement taken. If units are not used along with data, it will be very difficult to quantify the values that are recorded. Scientists all over the world use SI units in their works in order to ensure uniformity.

The information that should be added to the chart in order find out who ran a greater distance are the units used to measure distance each day

 

Since we are talking about distance, then it is just correct that the units that must be added to the chart should be the measurement of the distance. The formula for distance is d = st. By using this formula, then you can accurately find the distance based on the speed of the runner and the time it took for them to reach the distance allocated.

Which has greater heat capacity—iron, tin, or bismuth? Why do you say this?
emmasim [6.3K]

Answer:

Bismuth, because when three cubes of the same mass were heated and dropped into the same temperature water, the water the bismuth cube was dropped in heated up much less than the water with iron or tin.

In the reaction between bromine and sodium, a bromine atom gains an electron. What ion is formed? Is the bromine oxidized, or is
SVETLANKA909090 [29]

Answer: The ion formed after the reduction of bromine is Br^-

Explanation:

The electronic configuration of Sodium (Na) = [Ne]3s^1

The electronic configuration of Bromine (Br) = [Ar]3d^{10}4s^24p^5

From the above configurations, Sodium ion will loose 1 electron in order to gain stable electronic configuration and that electron is accepted by the Bromine atom because it is 1 electron short of the stable electronic configuration.

Na\rightarrow Na^++e^-   (oxidation reaction)

Br+e^-\rightarrow Br^-   (Reduction reaction)

Bromine atom is reduced to form Br^-

Reduction reactions are the reactions in which the element gain electrons.

Oxidation reactions are the reactions in which the element looses its electrons.
