Any of the Halogens (second to last vertical column going down)
a is 1 and b is 0 c is the same as b
hope this helps
Mililiters
% (V/V) = [V of solute / V solution ] *100
20.0 / 100 = V of solute / V solution = V of solute = 0.2 * V of solution
V of solution = 240.0 mL
=> V of solute = 0.2*240.0 mL = 48 mL
Answer: 48 mL
Answer:

Explanation:
Hello,
In this case, since the rate equation turns out as shown below due to the first-order kinetics:

Its integration results:

However, the rate constant is computed by considering the given half-life time as follows:

In such a way, the required time in minutes to diminish the concentration by 66.8% of the initial turns out:



Best regards.
Malleability is the property due to which substances tend to hammered into thin sheets when pressure is applied. Malleability is observed in metal as the metal atoms are bound by metallic bonds. The layers of metal atoms can roll over each other without breaking the metal bond when pressure is applied. In the periodic table malleability decreases as the metallic nature decreases. Among the given metals Al is the most metallic element, followed by Zinc an Carbon is a non metal. Therefore, the order of increasing malleability will be C, Zn, Al
