Explanation:

Identify the molecular shape of each lewis structure we have that:

1. Trigonal pyramidal

2. Tetrahedral

3. Trigonal planar

4. Bent

For an understanding through pictures of the location of electrons in an atom, we represent electrons as dots around the element symbol. The number of electrons available for bonding is indicated by unpaired dots. These symbols are called Lewis symbols.

The Lewis structure shows the formation of bonds in a molecule, as well as the atoms involved and the valence electrons of each of them, in this case was Trigonal pyramidal; Tetrahedral; Trigonal planar; Bent.

Answer:

Wax

Explanation:

The combustible material in a candle or its fuel is wax. Before the wax can become fuel, it first needs to get hot enough. To start that heating process, you first need to light the wick with another source of fire, such as a match. As the wick burns down the heat of the flame melts the wax around the wick.

Explanation:

n a laboratory experiment, you perform the above reaction. However, you only get 7.50g of Al. What was the percent yield of that experiment?

Answer:

5.60 Liters at STP

Explanation:

First you need the balanced reaction equation

2 H2 +  O2   ====>   2  H2O

4 g of oxygen ( O2 )  is   4/(15.999*2) moles of O2     (using periodic table)

  Twice the number of moles of H2O re produced   (from equation)

     at STP the volume of a mole of gas is 22.4 liter/ mole

       put all of this together  

         2 *   4 / (15.999*2) moles * 22.4 L/mole = 5.60 L

Energy is the fundamental need for lives. Fossil fuel is the energy source that is most needed in society. It is now replaced with solar energy as fossil fuels are nonrenewable resources.

Nonrenewable resources are energy sources that are finite in amount and get depleted after some time as it takes millions of years to produce these resources. Fossil fuels though are needed but are nonrenewable and cause pollution.

Solar energy is a renewable source that is present in abundant and infinite quantity and does not get depleted fast after they are used excessively. They are also environmentally friendly and do not produces much pollution.

Therefore, fossil fuel and solar energy are the most demanded sources.

Answer:

The molar mass of calcium hydroxide,

Ca(OH)2, is 74.092 g/mol.

Explanation:

The molar mass of a compound is determined by multiplying the subscript of each element in the formula by its molar mass (atomic weight on the periodic table) in g/mol, and adding the results.

The formula for calcium hydroxide is: Ca(OH)2

Molar Mass Ca(OH)2:

(1×40.078g/mol Ca)+(2×15.999g/mol O)+(2×1.008g/mol H)

=74.092 g/mol Ca(OH)2

Answer:

74.093 g/mol

Explanation:

Add the mass of Ca (found on the periodic table), the mass of 2 oxygens and 2 hydrogens together.

40.078+2(15.999)+2(1.00784)=74.093

Explanation:

150 grams is .15 liters

1 mole of gas at STP occupies 22.414 liters

.15 liter of hydrogen represents .15/22.414 =

0.0066922 moles of H2

equation is

Zn + 2HCl → ZnCl2 + H2

1 mole of Zn will make 1 mole of H2

0.0066922 moles of Zn will make 0.0066922 moles of H2

To convert this molar quantity of zinc into grams we simply multiply by the atomic mass of zinc, which is

65.38 g/mol;-

Mass of Zn required = 0.0066922 moles * 65.38 g/mol = 0.4375390381 grams

Answer:

Glycerine, water and methylated spirits have hydrogen bonds between the molecules. However, in water and Glycerine these intermolecular forces are very strong while in the methylated spirits they are slightly weaker. This leads to the higher boiling point for water and Glycerine.

We know the formula

C is concentration and V is volume

The new volume will be by using the relation between molarity and volume formula.

Molarity, also termed as molar concentration in a solution, is a method of determining how much material is present in a chemical solution.

Calculation of volume with the aid of molarity formula is shown below:

Volume is calculated by using the molarity formula.

[tex]M_{1} V_{1} = M_{2} V_{2}[/tex]

Where, M is molarity and V is volume.

It is given that, [tex]M_{1}[/tex] = 0.750 M , [tex]M_{2}[/tex] = 0.500 M, [tex]V_{1}[/tex] = 275 ml .

Now, put the value of given data in molarity formula.

[tex]M_{1} V_{1} = M_{2} V_{2}\\V_{2} = M_{1} V_{1} / M_{2}\\V_{2} = (0.750 M) (275 ml) / 0.500 M\\V_{2} = 183.34 ml[/tex]

Therefore, the volume will be 183.34 ml.
