Answer:

Please see the pictures attached below

The first picture has the values and the second has the formulas to construct the spreadsheet.

Explanation:

To construct the spreadsheet you should do the following:

1. First name the four columns as:

Number of folds

Thickness in inches

Thickness in feet

Thickness in miles

2. In the first column "Number of folds" put the numbers from 0 to 50 in order to calculate the thickness of each fold.

3. In the second column "Thickness in inches" put the following formula to show that each fold of a sheet is equal to multiply by 2 the original fold:

Thickness in inches = (thickness in inches(number of folds-1))*2

When the number of folds is 1, the formula will be:

Thickness in inches = 0.000 * 2 = 0.000

When the number of folds is 2, the formula will be:

Thickness in inches = 0.004 * 2 = 0.008

When the number of folds is 3, the formula will be:

Thickness in inches = 0.008 * 2 = 0.016

When the number of folds is 4, the formula will be:

Thickness in inches = 0.016 * 2 = 0.032

And so on until 50.

3. In the third column you only multiply by 0.08333 the value of inches to convert it to feet.

4. And in the fourth column you should multiply the value of inches by 0.0000157828 to convert it to miles.

Stells [14]

Answer:

Large crystals

Slowly

Explanation:

Recrystallization is a procedure used to purify an impure compound in a solvent. The concept used here is that the solubility of most of the solids increases with increase in temperature.

Recrystallization is also called as method of fractional crystallization.

After a recrystallization, a pure substance will ideally appear as a network of <u>large crystals</u>. If this is not the case, it may be worthwhile to reheat the flask and allow the contents to cool more <u>slowly</u>.

Balance the equation.<br>P + 02 --&gt; P4O10​
charle [14.2K]

Answer:

4P + 5O₂ —> P₄O₁₀

Explanation:

From the question given above, we obtained:

P + O₂ —> P₄O₁₀

The above equation can be balance as illustrated below:

P + O₂ —> P₄O₁₀

There are 4 atoms of P on the right side and 1 atom on the left side. It can be balance by 4 in front of P as shown below:

4P + O₂ —> P₄O₁₀

There are 10 atoms of O on the right side and 2 atoms on the left side. It can be balance by putting 5 in front of O₂ as shown below:

4P + 5O₂ —> P₄O₁₀

Now the equation is balanced.
