F4OP2 I’m not sure if you were looking for the molecular formula or other formula
Answer:
pH=7
Explanation:
0.05 L*1.0M= 0.05 mol HClO2 and 0.05 mol NaOH
HClO2 + NaOH ---> NaClO2 + H2O
0.05 mol 0.05 mol
As we can see acid and base react completely, solution will be neutral, so pH =7
Answer:
1,500 mm
Explanation:
if 1 meter = 1000 mm, 0.5 meters is 500 mm, so 1.50 meters is 1,500 mm
Answer:

Explanation:
Hello,
In this case, the undergoing chemical reaction is:

Thus, for 0.904 g of precipitate, that is lead (II) iodide, we can compute the initial moles of lead (II) ions in lead (II) nitrate:

Finally, the resulting molarity in 30.8 mL (0.0308 L):
