The electron-dot formula of the hydrogen chloride HCl is shown in the attached diagram below.
<h3>What is the lewis electron dot diagram?</h3>A lewis electron dot structure can be used to express the number of bonds, the bonding atoms, and the lone pairs remaining in the atoms in the molecule.
Lines are represented between atoms that are bonded with each other and excess electrons or lone pairs are shown as dot pairs and are placed next to the atoms.
As the valence electrons in the chlorine atom are equal to 7 from the electronic configuration of the chlorine atom. First, the total number of valence electrons in the HCl molecule is 7 + 1 = 8.
A chlorine atom requires only one electron to complete its octet configuration. As the octet completes, the rest of the electrons of Cl are assigned as the lone pairs of the Cl atom. Therefore, the chlorine atom has 3 lone pairs of electrons on it and the hydrogen atom completes its duplet.

<u>Answer:</u> The mass of nickel that was originally heated is 28.4 grams.
<u>Explanation:</u>
When metal is dipped in water, the amount of heat released by metal will be equal to the amount of heat absorbed by water.
The equation used to calculate heat released or absorbed follows:
......(1)
where,
q = heat absorbed or released
= mass of nickel = ?
= mass of water = 150.0 g
= final temperature = 25.0°C
= initial temperature of nickel = 99.8°C
= initial temperature of water = 23.5°C
= specific heat of nickel = 0.444 J/g°C
= specific heat of water= 4.186 J/g°C
Putting values in equation 1, we get:
Hence, the mass of nickel that was originally heated is 28.4 grams.

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.
