Explain why is sodium less reactive than potassium

Chemistry
1 answer:
leva [86]3 years ago
8 0

Answer:

As potassium is larger than sodium, potassium's valence electron is at a greater distance from the attractive nucleus and is so removed more easily than sodium's valence electron. As it is removed more easily, it requires less energy, and can be said to be more reactive.

Annette [7]

Answer: A) Storing experimental samples

Explanation:

It is a common piece of laboratory glassware that can be made of glass or plastic and is opened at the top and closed at the bottom.

It cannot be used for measurements because there is no graduation indicating the volume.

Althought it can contain extra chemicals left over from an experiment, it is not the main proposal of the glassware that is to store samples.

It cannot be used in a microscope and the object for that is a microscope slide.

4 b + 3 o2 → 2 b2o3 if 8 moles of b and 4 moles of o2 are allowed to react, how many moles of b2o3 can be formed?
raketka [301]

The number of moles of  b2o3 that will be formed is determined as 4 moles.

<h3>Limiting reagent</h3>

The limiting reagent is the reactant that will be completely used up.

4 b + 3O₂ → 2b₂O₃

from the equation above;

4 b ------------> 2 b₂O₃

2b ------------> b₂O₃

2 : 1

3O₂  -------------> 2b₂O₃

3  :  2

b is the limiting reagent, thus, the amount of b2o3 to be formed is calculated as;

4 b ------------> 2 moles of  b2o3

8 moles -------> ?

= (8 x 2)/4

= 4 moles

Thus, the number of moles of  b2o3 that will be formed is determined as 4 moles.
