Explanation:

An image showing the range of cells is attached.

The task is to use autofill to fill the range of A9:H11 with the formatting from the range of A7:H8;

As shown in the image some cells are already filled. First, we highlight the cells A7:H8 and then we move the cursor to the end of the selected cell (precisely end of H8) over what is called Fill Handle and the cursor then turns into a black plus sign.

Hold down the right mouse button and drag over the wanted range of cells (A9:H11) and release.

A list of options is presented, this options include:

Copy cells, Fill series, Fill formatting only, Fill without formatting and so on.

From the displayed options, we select "Fill formatting only" and the cell (A9:H11) will have the same formatting as the cells (A7:H8).

To perform the autofill process, we take the following steps :

• Highlight the cells whose formatting we want to copy to other cells in our worksheet. In this case the cells to be highlighted are A7:H8
• We move our cursor the bottom - right corner of the highlighted cell, in this scenario, (bottom right corner of cell H8.
• At this point, a solid plus(+) sign appears, right click and hold on the + sign and drag the mouse over the preferred cells which we want the formatting of our highlighted cell to be applied (A9:A11).
• Once the mouse has been dragged over the preferred cell range , release the mouse and a number of formatting options appear.
• The required formatting option should be selected and it would applied on the preferred cell range.

Autofill option in Excel allows a certain formating option used in a cell or range of cells to be copied to a preferred cell range easily by simply dragging our mouse over the preferred range.

The enthalpy change ΔHrxn of the given reaction is 295 kJ/mol

Consider the hypothetical reaction whereby hydroxyl radical reacts with Chlorofluorocarbon. The balanced chemical equation can be expressed as:

\mathbf{OH_{(g)}+ CF_2Cl_{2(g)} \to HOF_{(g)} + CFCl_{2(g)} }

In the above chemical equation, the chemical species participating in the reaction are:

• O-H, C-F, C-Cl, and O-F

The bond energies of these chemical species are:

• O-H bond = 458.9 kJ/mol
• C-F bond = 485 kJ/mol
• C-Cl bond = 385 kJ/mol
• O-F bond = 190 kJ/mol

The ΔHrxn is the enthalpy change of the reaction and it can be expressed by using the formula:

\mathbf{\Delta H_{rxn} = \sum \ B.E (reactants) - \sum \ B.E (products)}

∴

\mathbf{\Delta H_{rxn} =\Big ( B.E (O-H) + 2B.E(C-F) +2B.E(C-Cl) \Big) - \Big( B.E (O-H) + B.E(O-F) } \\ \\ \mathbf{\ \ \ \ \ \ \ \ \ \ \ \ \ \ +B.E( C-F )+2B.E(C-Cl) \Big)}

By replacing the bond energies into the above expression, we have:

\mathbf{\Delta H_{rxn} =\Big ( 458.9 \ kJ/mol + 2(485 \ kJ/mol) +2(385 \ kJ/mol) \Big)} \\ \\ \mathbf{ - \Big( 458.9 \ kJ/mol + 190 \ kJ/mol +485 \ kJ/mol +2(385 \ kJ/mol)\Big)}

\mathbf{\Delta H_{rxn} =\Big ( 2198.9 \ kJ/mol \Big) - \Big( 1903.9\ kJ/mol\Big)}}

\mathbf{\Delta H_{rxn} =295 \ kJ/mol}

Therefore, provided that the enthalpy change is positive, it implies that the reaction is improbable and non-favorable.

Answer: A

Step-by-step explanation:

The best group to survey is option A. A.Get a list of salons in her town and use a deck of cards to pick 5 of them to visit. Survey all hairstylists that work in each salon.

What is the survey?

Surveys represent the list of questions that should be focused on for extracting particular data from the people. It could be conducted via the phone, mail, internet, malls, etc.

Since mags want to know the hottest hairstyle trend so here he should get the list of towns and then use the deck of cards so that she should pick 5 for visiting them. Therefore, the correct option is a.
