Answer:
C
Explanation:
There are roughly 454 grams for every pound. The conversion factor would look like this for converting 2 lbs of a sample into grams:
2lbs sample (454g sample/1lb sample) = sample in grams.
Nature: the way someone acts “biologically” vs Nurture: the way someone actually deals with how they act
Sr(s)+Mg²+(aq)→Sr²+(aq)+Mg(s)
Number of e-'s transfered are, n=2. Equilibrium constant,
K=2.69×10∧12
ΔG=-2.303RT logK
R=gasconstant=8.314J/mol-k
T= temperature in K= 25 oC=25+273=298K
The value we get ΔG = -70922.3J. But ΔG = -nFE
n= number of e-'s transfered in the reaction =2
F= farady = 96500C
E=potential of the cell is what?
∴E = ΔG.nF
=-(-70922.3)/2×96500)
=0.367v.
Answer:
must be equal to the amount of matter of the coal.
Explanation:
According to the law of conservation of matter, which states that matter can neither be created nor destroyed no matter how transformed it is. This means that the total amount of the reactants must equate the total amount of products.
In this question involving a reaction that causes a change of state from solid (coal) to gaseous (CO2 and other gases), in order to obey the law of conservation of mass, the total amount of the matter of the gases (products) must be equal to that amount of matter of the coal (reactants).
The exception to an octet of electrons would be the first noble gas, Helium, which only has two valence electrons. This primary affects the element hydrogen, which forms stable compounds by achieving two valence electrons.
