I'm not sure but I think is 2H2<span> => 4H</span>+ + 4e- and O2<span> + 4H</span>+<span> + 4e</span>-<span> => 2H</span>2<span>O</span>
Answer:
yes? is there a question...
Explanation:
A. Distillation. If the mixtures have different boiling points, the liquid with the lower boiling point will distill off first, followed by the other one.
“B. Filtration” is <em>incorrect</em>. Both liquids will pass through the filter paper.
“C. Sedimentation” is <em>incorrect </em>because it works only for a solid suspended in a liquid.
“D. Evaporation” is <em>incorrect</em>. Both liquids will pass into the atmosphere never to be seen again.
Answer:
Molarity = 0.202 M
7.36 g/L HCl
Explanation:
KOH + HCl ----> KCl + H2O
1 mol 1 mol
0.560mol/L *0.045L x mol/L*0.125L
0.560mol/L *0.045L = x mol/L*0.125L
x = 0.560mol/L *0.045L /0.125L= 0.2016 mol/L≈ 0.202 mol/L=0.202M HCl
M(HCl) = 1.0+35.5 = 36.5 g/mol
0.2016 mol/L*36.5 g/mol ≈ 7.36 g/L HCl
Answer:
it is 0.24 M
Explanation
Find the molarity of all ions in a solution that contains 0.165 moles of aluminum chloride in 820. ml solution. " Answer: [Al 3+1= 0.201 M. (CI) = 0.603M. ... 2) Find the molartiy of each ion present after mixing 27 ml of 0.25 M HNO3 with 36 ml of ... of each ion and the mass of any precipitate when a 0.300 mole of aluminum.
