Answer:
9.8 × 10^21
Explanation:
Equation of the reaction;
Cd(s) + Ni^2+(aq) ----> Cd^2+(aq) + Ni(s)
E°cell= E°cathode - E°anode
E°cathode= -0.25 V
E°anode = -0.40 V
E°cell= -0.25 - (-0.40)
E°cell = 0.65 V
∆G= -nFE°cell
∆G= -(2 × 96500 × 0.65)
∆G = -125450 J
From;
∆G= -RTlnK
lnK = ∆G/-RT
K= e^∆G/-RT
K= e^-[-(125450/8.314 × 298)]
K= 9.78 × 10^21
Answer : The total mass of carbon dioxide and water produced will be, 65.7 grams.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
![C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O](https://tex.z-dn.net/?f=C_6H_%7B12%7DO_6%2B6O_2%5Crightarrow%206CO_2%2B6H_2O)
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of
= Total mass of ![6CO_2+6H_2O](https://tex.z-dn.net/?f=6CO_2%2B6H_2O)
As we are given :
Total mass of
= 65.7 grams
So,
65.7 grams = Total mass of ![6CO_2+6H_2O](https://tex.z-dn.net/?f=6CO_2%2B6H_2O)
Therefore, the total mass of carbon dioxide and water produced will be, 65.7 grams.
Answer:
Protons = atomic #
Neutrons = Mass # - atomic #
Electrons = atomic # - charge ( If no charge electrons = 0 therefore electrons = atomic # only if No charge not including the ^ number thing)
The element is Palladium
atomic number = 46.
Atomic Mass = 106
Therefore The answer being
Protons = 106
Neutrons = 60
Electrons = 104
( Sorry im only in the 9th grade but i did the best i could) The reason electrons are 104 is because of the 2+ meaning 2+ more protons than electons.
Answer:
A variable is anything that can change or be changed. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment.
Fresh water= 1%
Salt water= 99%
