Desirae wanted to be her flag football team's star player so she made a training plan to run 3km a day. How many DECIMETERS will
MariettaO [177]

The total distance which Desirae would run in a week is equal to 21,000 decimeter.

<h3>What is a conversion factor?</h3>

A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.

Generally, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.

Next, we would convert the unit of distance in kilometer to decimeter as follows:

1 kilometer = 1,000 decimeter

3 kilometer = X decimeter

Cross-multiplying, we have:

X = 3 × 1000

X = 3,000 decimeter.

Note; 1 week is equal to 7 days.

The total distance which Desirae would run in a week is given by:

Total distance = 7 × 3,000

Total distance = 21,000 decimeter.

Which element is more reactive? *<br> Cs<br> Rb
Anarel [89]

Answer:

Rubidium is a typical but very reactive member of the series of alkali metals. It is appreciably more reactive than potassium, but less so than caesium, and so would be expected to react more violently with those materials that are hazardous with potassium or sodium.

Which element would you expect to be more metallic?<br> (a) S or Cl (b) In or Al (c) As or Br
Natalija [7]

Explanation:

When we move across a period from left to right then there will occur an increase in electronegativity and also there will occur an increase in non-metallic character of the elements.

As sulfur (S) is a group 16 element and chlorine (Cl) is a group 17 element. Hence, sulfur (S) is more metallic in nature than chlorine.

This means that chlorine (S) is less metallic than chlorine (Cl).

Both indium (I) and aluminium (Al) are group 13 elements. And, when we move down a group then there occur an increase in non-metallic character of the elements. As indium belongs to group 13 and period 5 whereas aluminium belongs to group 13 and period 3.

Therefore, aluminium (Al) is more metallic than indium (In).

Arsenic (Ar) is a group 15 element and bromine (Br) is a group 17 element. Therefore, arsenic is more metallic than bromine.
