First, we discuss the given values. E₀ cell is the reduction potential of the cell. This indicates the tendency of a given substance to be reduced. Next, ΔG is the Gibbs free energy, and a negative Gibbs free energy indicates the likelihood of a reaction taking place. Therefore, for a spontaneous reaction, ΔG will be negative and E₀ cell is positive.
The second option is correct.
Answer:
pentaphosphorus heptanitride.
Explanation:
Answer:
A. 100 g of this solution contains 39 g of phosphoric acid
Explanation:
The formular for percentage by a mass id usually given as;
( Mass of element / Mass of compound ) * 100%
So when a solution contains 39% by mass of phosphoric acid, it means that in 100 units of the solution, there are 39 units of phosphoric acid.
The only option that satisfies this is option A. 100 g of this solution contains 39 g of phosphoric acid
The bowling ball have more gravitational potential energy as it sit on top of the building
<u>Explanation:</u>
The energy that is possessed by an object due to the position of that object in the field of gravity is called Gravitational potential energy . The object that is present in the place that is very closer to the Earth's surface has a constant gravitational potential energy. When an object is at certain height there is a necessity of force for lifting that object form that height.
This is applies to the gravitational potential energy also.When two objects are placed at different heights, the object that is placed at the greater height will have more potential energy. This is because, the force necessary to take the object from greater height will be more.
Answer:
See explanation
Explanation:
In this question, we have to follow the IUPAC rules. Lets analyze each compound:
a. 1-methylbutane
In this compound we have a chain of 5 carbons, so the correct name is <u>Pentane.</u>
b. 1,1,3-trimethylhexane
In this compound, we longest chain is made of 7 carbons, so, we have to use the name "heptane". Carbon one would be the closet one to the methyl group, so the correct name is <u>2,4-dimethylheptane.</u>
c. 5-octyne
In this case, carbon 1 would be the closet one to the triplet bond. With this in mind, the correct name is <u>oct-3-yne.</u>
d. 2-ethyl-1-propanol
In this compound, we longest chain is made of 4 carbons, so, we have to use the name "butane". Carbon one would be the carbon with the "OH" group, so the correct name is <u>2-methylbutan-1-ol.</u>
<u>e. 2.2-dimethyl-3-butanol</u>
In this case, carbon 1 would be the closet one to the "OH". With this in mind, the correct name is <u>3,3-dimethylbutan-2-ol.</u>
See figure 1
I hope it helps!
