Explanation:

The reaction rate decreases with a decrease in temperature. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. Differences in the inherent structures of reactants can lead to differences in reaction rates.

Restaurant​ a's chicken salad contains the same number of grams of fat as the chicken salad of restaurant
german
To compute for grams of fat in each salad:

We know that, A = C.

And B is 5 grams more, so it is B = 5 + A

And the total fat is 65, so A + B + C = 65 grams.


Computation:

A + (5 + A) + A = 65

3A + 5 = 65

3A = 60

A = 20

A = 20

B = (65 - 40) = 25

C = 20

What effect does fermented sugar have in beer brewing
LiRa [457]

Answer:

If the sugar concentration level of the must becomes too high at any given point--either at the beginning or during the fermentation--it starts to have an inhibiting effect on the yeast's ability to produce alcohol. In other words, the higher sugar concentration starts to act as a preservative effecting the fermentation in a negative way.

Explanation:

Fermentation is the process by which yeast converts the glucose in the wort to ethyl alcohol and carbon dioxide gas -- giving the beer both its alcohol content and its carbonation.

What kind of Romance Novels would kids between the age of 14-18 read. Whether it is an actual book or a book made on sites like
alexdok [17]
A book series that a 14-18 year old would read could be the books by Sarah Mlynowski. A book that I have read that is really good it Gimme A Call. It is based on a girls point of view. It is fiction because of the idea that the book revolves around the character getting a call from her future self telling her to do things differently with her life. The book isn't mainly about romance, but it does have some really good topics that teens can deal with. Also, when you are looking for a romance novel keep in mind that there are different levels of romance books. There are the type of books where there is only flirting and the usual teenage dating, but then there are books with very, and I mean very, unpleasing scenes.

Find the energy required to melt the copper once it's reached the melting point.
belka [17]
The answer has to depend on the mass of the copper that you're trying to melt. 

But there is a formula which you can calculate the energy required if you have the information of the mass. This formula requires the value called specific latent heat of fusion, which is the energy required to melt or freeze a specific mass of copper without changing its temperature but change its state. 
E = m l_{f}
E is the total energy required, m is the mass, and lv is the specific latent heat of fusion of copper. 

Usually, in questions, lv is given. But we can also look it up online which is around 205kJ kg^-1 
this means, to melt or freeze a copper, we need to work the mass multiplied by 205kJ in order to calculate its total energy needed or released.

Sound travels most quickly through solids because _____. solids have greater frequencies the molecules in solids are very close
uranmaximum [27]
Sound travels most quickly through solids because _____.

answer is: because solids r the most sense.

The distance between molecules in solids r very small.Because they are so close, they can collide very quickly, i.e. it takes less time for a molecule of the solid to 'bump' into its neighbor. Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids.
