Molar mass of sodium=23g
2 mole sodium gives 2 g H2
i.e 46g sodium gives 2g H2
so 65.4g will give=2.84g H2
now no. of molecules = 2.8/2*avogadros number

What is this balanced?<br> Al2O3---&gt; Al+O2
saveliy_v [14]

The balanced equation :

<em>2Al₂O₃⇒ 4Al+3O₂</em>

<h3>Further explanation</h3>

Given

Reaction

Al₂O₃⇒ Al+O₂

Required

Balanced equation

Solution

A chemical reaction is said to be balanced if the number of elements involved in the reaction is the same (either the reactants or the products)

The reaction above is said to be unbalanced because the number of elements Al and O in the reactants and products is not the same.

The balancing step

1. Give a coefficient

Al₂O₃⇒ aAl+bO₂

2. Make an equation

Al, left = 2, right = a⇒a=2

O, left = 3, right = 2b⇒2b=3⇒b=3/2

The equation becomes :

Al₂O₃⇒ 2Al+3/2O₂ x2

<em>2Al₂O₃⇒ 4Al+3O₂</em>

Compounds Lab Report
lukranit [14]

Name and Title:

Colleen DeBruin, Hillary Mulkavits, 11/18/2020, compounds lab.

Objectives(s):

to build chemical compounds from known elements

Hypothesis:

if I use oxygen hydrogen and carbon then I can make five new compounds in four minutes

Procedure:

The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using your summary questions at the end of your virtual lab activity, please clearly define the dependent and independent variables of the experiment.

Data:

Record the composition of each of your compounds below. Be sure to include the number of atoms for each element. An example has been supplied for you.

Compound Name Chemical Formula Sodium (Na) Atoms Calcium (Ca) Atoms Hydrogen (H) Atoms Oxygen (O) Atoms Carbon (C) Atoms Chlorine (Cl) Atoms

Ex: Sodium

hypochlorite NaClO 1 0 0 1 0 1

Water H20 o 0 1 2 0 0

Glucose C6H12O6 0 0 12 6 6 0

Formic/methanoic acid HCOOH 0 0 2 2 1 0

Butanoic Acid C3H7COOH 0 0 8 2 4 0

Carbon Dioxide C02 0 0 0 2 1 0

Carbon Monoxide CO 0 0 0 1 1 0

Fructose C6H12O6 0 0 12 6 6 0

0 0 0

0 0 0

0 0 0

Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.

I found as many combinations of carbon hydrogen and oxygen as possible

If there is a job that combines elements you would be doing that every day making it an every day matter

elements are like people, they are all different causing them to react differently and be more reactive

H20 has four because there are 2 oxygen and one hydrogen because of the numbers in the name of the compound

Yes because two elements can form two different types of bonds causing different outcomes

If this isn't right I'm sorry but I had it as an assignment so we will get it wrong together lol
