Answer: Use the titration formula
Explanation:
The reaction would be as shown below;
Na2SO4 + Ca(NO3)2 = CaSO4 + 2 NaNO3
The moles of NaSO4 will be;
= 0.05 × 0.0154 = 0.00077 moles
While the number of moles of Ca(NO3)2
= 0.05 × 0.0128 = 0.00064 moles
The mole ratio of sodium sulfate and calcium nitrate is 1:1
Ca(NO3)2 is the limiting reactant, so ignoring the Ksp of CaSO4, zero percent of the Ca^2+ ions remain unprecipitated.
Total solar eclipses would be more common, because it would be easier for the moon to cover it, which is a solar eclipse.
Answer:
CH3COCH3
Explanation:
Acetone is an organic compound belonging to the organic ketone function.
To recognize which function a compound belongs to, we must analyze its functional group. For example, hydroxyl (OH) is characteristic of alcohols. For ketones, the functional group is carbonyl, which is represented below.
Analyzing the options, we can notice that NH3, HNO3, KClO2 and H3PO3 are inorganic compunds, because they don't have carbon in their structures. KOH has the hydroxyl, so it's a alchol, and CH3COCH3 may be writing as a ketone.
