Answer: The reaction of formation of ions by fluorine and potassium is .
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 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 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.
Thus, we can conclude that the reaction of formation of ions by fluorine and potassium is .
Answer:
<h2>Density = 0.75 g/cm³</h2>Explanation:
Density of a substance is given by
<h3>From the question
mass of the wood = 180 g
Since the wood is a cuboid we can find the volume using the formula
Volume = length × width × height
From the question
length = 10cm
width = 6 cm
height = 4 cm
Volume = 10 × 6 × 4 = 240 cm³
Substitute the values into the above formula and solve for the Density
That's
<h3>We have the final answer as
<h3>Density = 0.75 g/cm³</h3>Hope this helps you
