Explanation:
Answer:
-1.78 V
Explanation:
There are several rules required to calculate the cell potential:
- given standard cell potential, we may reverse the equation: the products of a given reaction become our reactants, while reactants become our products in the reversed equation. For a reversed equation, we change the sign of the cell potential to the opposite sign;
- if we multiply the whole equation by some number, this doesn't influence the cell potential value. It only produces a different expression in the equilibrium constant.
That said, notice that the initial reaction with respect to the final reaction is:
- reversed: chromium(III) cation and chloride anion become our reactants as opposed to the products in the initial reaction, so we change the sign of the cell potential to a negative value of -1.78 V;
- each coefficient is multiplied by a fraction of . It doesn't influence the value of the cell potential.
Thus, we have a cell of E = -1.78 V.
The question is incomplete, here is the complete question:
Consider the following two-step process (unbalanced). How many moles of water can be formed from 0.680 moles of ?
Enter your answer numerically to three siginificant figures.
<u>Answer:</u> The amount of water formed from given amount of nitrogen gas is 1.38 moles
<u>Explanation:</u>
We are given:
Moles of nitrogen gas = 0.46 moles
The balanced chemical equation follows:
.......(1)
.......(2)
<u>From equation 1:</u>
By Stoichiometry of the reaction:
1 mole of nitrogen gas produces 2 moles of ammonia
So, 0.46 moles of nitrogen gas will produce = of ammonia
<u>From equation 2:</u>
By Stoichiometry of the reaction:
4 moles of ammonia produces 6 moles of water
So, 0.92 moles of ammonia will produce = of water
Hence, the amount of water formed from given amount of nitrogen gas is 1.38 moles
From Earth's<span> density we can estimate what elements must compose the </span>Earth; an iron core<span> just happens to estimate </span>Earth's<span> mass the best. Now from energy waves, geologists use seismometers to measure movements in </span>Earth's<span> interior (e.g. Earthquakes), These energy-waves form compressional and shear waves</span>
The proportion of long-tailed squirrels may have increased due to increased food availability.
The statement has it that the percentage of long tailed increased also that the long tailed are better at jumping and balancing on trees.
The first option could is tempting but saying decrease in trees would not likely support the argument.
The last option has more sound options as more food availability may lead to population increment
Hope it helps....
