The answer is volume that is volume limits the precision of data obtained in an experiment .
As while pouring of the liquids, we control the volume, but it can have been off. And this could results in the wrong mole to mole ratio.Thus it limits the precision, So the answer is that volume limits the precision of data obtained in an experiment .
Cu2S is the one that is going to form a precipitate and Cu(NO3)2 will not form a precipitate because it is soluble. It is a fact that those that are insoluble will form a precipitate. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
Answer:
The oxygen-rich blood is then pumped out to your body through your arteries. It's bright red at this point. ... Your lips have a lot of these capillaries, which is why they're red. Your blood, now exhausted of its oxygen, is dark red as it now returns to your heart through your veins.
Explanation:
42.6897 grams of carbon dioxide would be produced from the following reaction, if 175 kJ of energy is given off.
<h3>How do we calculate moles?</h3>
The mole (symbol mol) is the SI base unit of material quantity. The amount of substance in an object or sample is a measure of how many elementary entities of a certain substance are present.
Given chemical reaction is:
→ 
From the stoichiometry of the reaction, it is clear that 2 moles of carbon dioxide are produced.
Actual moles will be calculated by using the enthalpy and energy value as:
Actual moles of 
= 275kJ × (
) = 0.97 moles.
Grams of carbon dioxide = moles X molar mass of carbon dioxide.
Grams of carbon dioxide = 0.97 X 44.01 g/mol
Grams of carbon dioxide = 42.6897 g

Electrons orbit in orbitals (s, p, d, f).
Technically, the number of orbitals extend to infinity, but the effective nuclear charge decreases as the distance increases.
