Answer:
74 ± 1 klumps; 1.44 ± 0.01 glips
Step-by-step explanation:
8. <em>Smallest scale
</em>
There are no divisions between 0 and 10, so the smallest scale division is 10 klumps.
9. <em>Length of line
</em>
You should estimate to the nearest tenth of the smallest scale division.
The line appears to be slightly less than half-way between 70 and 80.
I estimate the length of the line to be 74 klumps, with an uncertainty
of ±1 klump.
10. <em>Smallest scale division
</em>
There are 10 divisions between 0 and 1, so the smallest scale division
is 0.1 glip.
11. <em>Length of line
</em>
The line appears to be slightly less than half-way between 1.4 and 1.5.
I estimate the length of the line to be 1.44 glips, with an uncertainty
of ±0.1 glip.
A. or Sodium. All the other elements have the same amount of valence electrons and that makes them attract to each other.
We are given ΔG°rxn = -30.5 kJ/mol for the following reaction:
ATP + H₂O → ADP + HPO₄²⁻
We are given a series of concentrations for each of the species and are asked to find the value of ΔG for the reaction. We can use the following formula:
ΔGrxn = ΔG°rxn + RTlnQ
We can use R = 0.008314 kJ/molK; T = 335.15 K and Q is the reaction quotient which can be found as follows, and be sure to first convert each concentration of mM to M:
Q = [ADP][HPO₄²⁻]/[ATP]
Q= [0.00010][0.005]/[0.005]
Q = 0.0001
Now we can use the above formula to solve for ΔGrxn.
ΔGrxn = -30.5 kJ/mol + (0.008314)(310.15)ln(0.00010)
ΔGrxn = -54.3 kJ/mol
The value of ΔGrxn = -54.3 kJ/mol.
When Lead (II) acetate and Hydrogen sulfide react, they form Lead sulfide and Acetic acid. The reaction is a reduction-oxidation (redox) reaction.
The balanced chemical reaction is this:
Pb(C2H3O2)2 + H2S --> PbS + 2C2H4O2
And the net ionic reaction is this:
Pb2+ + S2- --> PbS
Answer:
PH is a logarithmic scale it means that 1 increase or decrease in PH changes concentration tenfold
PH 3 is 10 times more acidic than PH 4
