Answer:
th mol
Explanation:
When you balance an equation, you can refer back to the coefficients when calcuating mol and molar mass from the given information about one reactant to antoher reactant ot product. you use the coeffiecients for mol-mol ratio.
for example. if you are given A +3 B -----> 6C + 5D, and you have 10 mol of A and you have to find how many mols of C with 10 mol of A. then you would ratio it as A: C = 10A: 10C= 10(1): 10(6)= 10:60. so with 10 mol A you can make 60 mol C.
Answer:
Explanation:
In this problem, we need to convert 
to miles per hour
We know that,
1 mile = 1.609 km
1 hour = 3600 seconds
Hence,
The answer would be A. which says the emitter- base junction must be forward biased, and the collector- base junction must be reverse biased.
I'm not suree.. is his science?
Answer: 1.19 V
Explanation:
Standard potential for an electrochemical cell is given by:
= standard electrode potential =
The 
values have to be reduction potentials.
Given:
Cadmium is losing electrons , undergo oxidation and thus act as anode. mercury is gaining electrons, undergo reduction and thus acts as cathode.
= standard electrode potential =
Thus the standard potential for an electrochemical cell with the cell reaction is 1.19 V.
