The continuous movement of the bike or along those lines
To solve this problem, we make use of the Faraday’s law
for Electrolysis. The formula is given as:
I t = m F / e
where the variables are,
I = current = 24.4 A
t = time = 46 min = 2760 s
m = mass produced = (unknown)
F = Faraday’s constant = 96500 C/equivalent
e = gram equivalent weight of gold
The gram equivalent weight is calculated by dividing the
molar mass with the amount of charge produced per atom. Gold has charge of 3+
therefore the gram equivalent weight is:
e = (196.97 g/mol)(1 mol/3 equivalents) = 65.66
g/equivalents
Solving for the mass m:
m = e I t / F
m = (65.66 g) (24.4 A) (2760 s) / (96500 C)
m = 45.82 g
The type of atoms present in the chemical compound and the proportion or how many specific atoms are respect to other atoms in the chemical compound.
Answer:
There is 18.8% lithium by mass in second sample
Explanation:
Both the two samples are pure lithium carbonate. So % lithium by mass will be same in both samples. This can be proved mathematically as follows-
Let's assume weight of first sample is x g
So, 100 g of sample contains 18.8 g of lithium
Hence, x g of sample contains 
g of lithium
Now, the second sample has weight equal to 2x g
So, 2x g of sample contains 
g of lithium
So, % lithium by mass in second sample = 
% = 18.8%
False.
This is because there are three different rocks, metamorphic, sedimentary, and igneous. Thus, meaning that there are three different pathways, making this statement false.
Hope this helps!
