Explanation:
No as oxygen is not balance
In reactants side there is 12 oxygen and in the product side there is 8 oxygen
Answer:
1.33 Å
Explanation:
Given that the edge length , a of the KCl which forms the FCC lattice = 6.28 Å
Also,
For the FCC lattice in which the anion-cation contact along the cell edge , the ratio of the radius of the cation to that of anion is 0.731.
Thus,
.................1
Also, the sum of the radius of the cation and the anion in FCC is equal to half of the edge length.
Thus,
...................2
Given that:
To find,
Using 1 and 2 , we get:
<u>Size of the potassium ion = 1.33 Å</u>
<span>For addition and subtraction you round to decimal places.
Round the number so that it has the same number of decimal places as the number in your data that has the least number of decimal places.
9 cm + 2.8 cm = 11.8 cm
the 9 has no decimal places so
= 12 cm
(this is rounded to 0 decimal places.)

Filtration. A filter is a porous barrier. Heterogeneous means it's a visible mixture, i.e large enough particles to see.
