Assuming that you need a simple model for your answer:


W=F*h


F: weight, W: Energy, h: height


F=W/h => 3 m (since all units are in SI)

dimaraw [331]

Answer:

I will need  six (6) bags of potting soil

Explanation:

Since you plan on planting in 10 pots and need 15 cups of potting soil per pot, the total amount of potting soil you need <em>(in cups)</em> is 10 X 15 = 150 cups of potting soil.

We have that a bag contains 25 sups. to get the number of bags needed, we have to divide 150 by 25. This will give us 150 / 25 = 6 bags.

Therefore, I will need  six (6) bags of potting soil

Write the recation of formation of ions by fluorine and potassium​
bekas [8.4K]

Answer: The reaction of formation of ions by fluorine and potassium​ is K^{+} + F^{-} \rightarrow KF.

Explanation:

Atomic number of potassium is 19 and its electronic distribution is 2, 8, 8, 1. So, in order to attain stability it needs to lose 1 electron due to which it forms K^{+} ion.

Atomic number of fluorine is 9 and its electronic distribution is 2, 7. In order to attain stability it needs to gain one electron and hence forms F^{-} ion.

Therefore, when both these ions come in contact with each other then it leads to the formation of KF compound.

The reaction equation for this is as follows.

K^{+} + F^{-} \rightarrow KF

Thus, we can conclude that the reaction of formation of ions by fluorine and potassium​ is K^{+} + F^{-} \rightarrow KF.
