I think it is 3, but I'm not sure
ANSWER:
all of them
Explanation:
preciseness is measured by how many decimal places are used not by accuracy. since all of these are to the same decimal place they are all equally precise even if they are inaccurate.
Option C is correct.
Lactic acid fermentation is a metabolic process in which a glucose molecule turns into lactate which again turn into lactic acid.
In this process a glucose molecule produces 2 molecule of lactate and releases 2 NADH. The NADH is produced from the reduction of NAD+ and ADP takes the phosphates to release 2 molecules of ATP.
Answer:
no. of moles of PbI₂ = 14 moles
Explanation:
Data Given:
no. of moles of HI = 28 moles
no. of moles of Pbl₂ = ?
Reaction Given
Pb + 2HI -------→ Pbl₂ + H₂
Solution:
To solve this problem we have to look at the reaction
Reaction:
Pb + 2HI -------→ Pbl₂ + H₂
2 mol 1 mol
So if we look at the reaction 2 mole of hydrogen iodide (HI) gives 1 moles of Lead iodide (PbI₂), then how many moles of Lead iodide (PbI₂) will be produced by 28 moles of hydrogen iodide (HI)
For this apply unity formula
2 mole of HI ≅ 1 moles of PbI₂
28 mole of HI ≅ X moles of PbI₂
By Doing cross multiplication
moles of PbI₂ = 28 moles x 1 moles / 2 mole
moles of PbI₂ = 14 mole
28 mole of HI will produce 14 moles of PbI₂
