Answer:nitrogen fixation i think
Explanation:
It is because precise amount measured is required for the reaction to take place chemically, and an accurate conclusion will prevent any dangerous and misleading conclusions made due to inaccurate data.
For example, in physics, every measurement we state the instrument uncertainty after the measurement, stating that it is not a definite certain measurement, but the smaller the value for the uncertainty, the more precise that instrument's data is.
Precise is important in terms of knowing how many moles or grams of reactant is required for this reaction to complete without any shortage or excess chemically. Accuracy is based on the conclusions we make in regards to the data and observations we make experimentally.
Answer:
Electrons will flow from left to right through the wire.
Pb^2+ ions will be reduccd to Pb metal.
The concentration of Sn2+ ions in the left compartment will increase.
Explanation:
Looking at the relative electrode potentials of the two metals
Sn= -0.14
Pb=-0.13
Tin is expected to function as the anode (left hand half cell) and lead as the anode (right hand half cell) tin oxidizes to sn^2+ hence its concentration increases on the left compartment while lead is reduced to ordinary lead metal on the right hand half cell . since oxidation occurs on the left hand side, electrons flow from left to right.
This is right
Reduce the concentration of NICO4
Answer:
3750 cm.
Explanation:
You multiply the three side measurements to find the volume.
25cm·10cm·15cm
375cm·10cm
3750 cm.
