Decide which element probably has a boiling point most and least similar to the boiling point of cesium.
natka813 [3]

Answer:

Take a look at the attachment below

Explanation:

Take a look at the periodic table. As you can see, Rubidium is the closest element to Cesium, and happens to have the closest boiling point to Cesium, with only a difference of about 30 degrees.

Respectively, you would think that fluorine should have the least similarity to Cesium with respect to it's boiling point, considering it is the farthest away from the element out of the 4 given. This is not an actual rule, there are no fixed trends of boiling points in the periodic table, there are some but overall the trends vary. However in this case fluorine does have the least similarity to Cesium with respect to it's boiling point, a difference of about 1,546.6 degrees.

<em>Hope that helps!</em>

How long will it take for 100 grams of a substance with a half-life of 2 years to decay to a mass of 50 grams?
Elis [28]

Answer:

<u>2 years</u> to decay to a mass of 50g.

Explanation:

given:

100g of substance with a half life of 2 years

to a mass of 50g

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

                          ln 2             0.693

Half life T1/2 = ----------  =  -----------

                              λ                  λ

where  λ = rate constant

The initial amount of 100 grams is decaying to a mass of 50 grams is half of its initial value.

Therefore, it will take 2 years for the decay.
