WILL GIVE BRANLIEST WILL FOREVER BE GREATFUL EASY BUT I WAS TO LAZY TO LEARN 13. How much of 0.05M HCl solution can be made by diluting 250 mL of 10M HCl?

16. What are the oxidation numbers for each element is the compound: PbO2

0.05 * V1 = 250 * 10  

V1 = 2500 / 0.05  

V1 = 2500 * 20  

V1 = 50000 mL  

V1 = 50 Liters .  

In PbO2 , oxygen exhibits an oxidation number of −2 (since it's not a peroxide or superoxide): Let the oxidation number of Pb be x . Then, for the compound to be neutral, the oxidation numbers of all atoms should add up to zero

Explanation:

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
