The answer is b although if you think about it all could apply
Answer:
0.006 mol of CaCl2 are present
Explanation:
Use dimensional analysis for this:
60.0 mL CaCl2/1 * 1 L/1000 mL * 0.10 mol/1 L = 0.006 mol
If you were to write this as fractions out on paper, you'll see that all of the units will cancel out and you'll be left with moles of CaCl2.
**REMEMBER** that molarity (M) is talking about how many moles of that substance is present in one Liter of solvent.
Hope this helps :)
Answer:
This is an acid-base reaction (neutralization): H 2SO 4 is an acid, Ca(OH) 2 is a base.
...
1 H2SO4 + Ca(OH)2 → H2O + CaSO4
2 H2SO4 + Ca(OH)2 → CaSO4 + HOH
3 H2SO4 + Ca(OH)2 → H2O + CaOH2SO4
4 H2SO4 + Ca(OH)2 → H2O + Ca(HSO4)2
5 H2SO4 + Ca(OH)2 → H2O + (CaOH)2SO4

Answer:
one mole of oxygen will produce
moles of water
Explanation:
The balanced chemical reaction is as follows -
2 C2H2 + 5 O2 --> 4 CO2 + 2 H2O
As we can see in this reaction
5 mole of oxygen (on the reactant side) will produce 2 mole of water (on the product side)
Hence, one mole of oxygen will produce
moles of water
