There are a total of 40 valence electrons in the PCl5 Lewis structure. Remember when you draw the Lewis structure for PCl5 that Phosphorous (P) is in Period 3 on the Periodic table. This means that it can hold more than 8 valence electrons.

How many gallons of concentrated sulfuric acid (density of 1.84 g/cm3) are required to have a mass of 184.33 pounds?
KengaRu [80]

After series of conversion from one unit to another, the number of gallons was found to be 12 litres

<h3>Density, Mass and Volume</h3>

Given Data

  • Density of Sulfuric acid = 1.84 g/cm3
  • Mass of Sulfuric acid = 184.33 Pounds

Conversion from pounds to Gram

1 kg ---------2.204 lb

x kg ---------184.33 lb

x = 184.33/2.204

x = 83.634 kg

hence the mass in gram = 83.634*1000

mass in gram = 83634 g

Now let us find the volume

We know that density = mass/volume

volume = mass/density

volume = 83634/1.84

volume = 45453.26 cm^3

Convert cm^3 to litres

Volume in litres = 45453.26 /1000

Volume in litres = 45.45 Litres

Convert from Litres to Gallons

1 gallon = 3.79 L

x gallons =  45.45 L

x =  45.45/3.79

x gallons = 11.99 L


Approx = 12 Litres

2KCIO3 ----------&gt; 2KCI + 302<br> How many moles of KCIO3 are needed to make 3.5 moles of KCL?
lyudmila [28]

Answer:

3.5 mol KClO3

Explanation:

Given 3.50 moles of KCl as the target amount in the problem, used the coefficient of the balanced chemical reaction involved to determine the number of moles of potassium perchlorate needed.

x mole of  KClO3  = 3.5 mol  KCl x [(2 mol KCl)/ (2 mol KClO3)] = 3.5 mol KClO3

x mole of  KClO3 = 3.5 mol KClO3

Express 975,000 in scientific notation
kodGreya [7K]

9.75 x 10^5

A number in scientific notation has the form <em>a x 10^b</em> where

• a is the <em>coefficient</em>

• b is the <em>exponent</em>

Here are the steps to convert a number greater than 1 to scientific notation.

a) Find the coefficient

Put the decimal point after the first digit and drop the trailing zeroes

<u>9.75</u> 000

The coefficient is 9.75 .


b) Find the exponent

Count the number of digits after the first digit.

In 975 000 there are five digits after the 9. Therefore, the exponent is 5.

c) Write the number

We write 975 000 as 9.75 x 10^5.
