5 0

Answer: V = 5.1 L

Explanation: To find the new volume, we will use the formula of Combined Gas Law and derive V2. We also need to convert first the temperature in Kelvin and convert torr to atm ( 1 atm = 760 torrs ).

A 3000 MWt fast reactor has a 42% efficiency. This reactor operates for 23 months followed by a 1 month down time for refueling
n200080 [17]

Answer:

capacity factor = 0.952

Availability factor = 0.958

Explanation:

1) capacity factor

capacity factor = actual power output /  maximum power output

                        = (actual power output)/(efficiency * rated power output)

                       = \frac{1200}{\frac{42}{100}*3000}

= 0.952

2) Availability factor

Availability factor  = Actual operation time period/ total time period

                            = 23/24 = 0.958

For single bonds between similar types of atoms, how does the strength of the bond relate to the sizes of the atoms? Explain.
uysha [10]

When comparing single bonds between atoms of comparable types, the stronger the bond is, the bigger the atom, the weaker it is.

The length of the X-H bond lengthens while the strength of the bond shortens with increasing halogen size (F-H strongest, I-H weakest). When comparing single bonds between atoms of similar sorts, the larger the atom, the weaker the bond. It can be explained by the fact that less energy is required to break the bond the bigger the atom's atomic size. The force of attraction from the nucleus to the outermost orbit will be less for iodine since it has a larger atom than the other elements in the group.

Answer:

²³⁵₉₂U

Explanation:

               ²³⁵₉₂U

The nuclear symbol of U- 235 should be written as;

   

235 is the mass number of uranium. The mass number is written as the superscript before the symbol of the element.

92 is the atomic number of uranium. It is written as the subscript before the symbol of the element.

He table shows the percentages of hydrocarbons that are found in a sample of crude oil.
Flura [38]

Answer is: a mixture.

Crude oil is mixture (solution) consist of several different hydrocarbons (alkanes, alkenes...). This hydroalkanes can be separated from mixture (crude oil) using distilation (usually fractional distillation), because they have different boiling points.  

Proportion of hydrocarbons is diiferent in varios parts of the world.

Solution is homogeneous mixture composed of two or more substances.
