K will give up an electron more easily than Br.
<em>V= 110mL = 110cm³ = 0,11dm³</em>
<em>C = 1,244 mol/L = 1,244 mol/dm³</em>
C = n/V
n = 1,244×0,11
<u>n = 0,13684 moles</u>
<em>mCa(OH)₂ = 74 g/mol</em>
1 mole Ca(OH)₂ ------------ 74g
0,13684 ---------------------- X
X = 74×0,13684
<u>X = 10,12616g</u>

Answer:10g of Fe produces 14.37g of Fe2O3
7g of O2 produce 46.84g of Fe2O3
Explanation:
The maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 ×
P a. So, the correct option is (b).
Radiation pressure is the name for the force electromagnetic wave particles exert on a surface. It is inversely related to the wave's speed. Given data
Solar constant ( S ) = 1350W / m ^2
Now, the radiaton pressure is given by
P = 2 S /c
where c is the speed of the light
P = 2 × 1350 /3 × 10 ^8
P = 9 ×
P a
For a black surface, P = 4.5×
P a
Therefore, maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 ×
P a
