Answer:

This reaction has infinite ways to be balanced

Explanation:

To balance this equation we can use the algebraic method:

N2O4(g) + CO → NO(g) + CO2(g)+NO2(g)

Where we write each molecule as a letter:

A + B → C + D + E

Then, we write the equations according the number of atoms of each molecule. That is:

Oxygen → 4A + B = C + 2D + 2E <em>(1)</em>

Nitrogen → 2A = C + E <em>(2)</em>

Carbon → B = D <em>(3)</em>

Then, we have to give 1 arbitral number for a letter. For example:

B = 1; D = 1

<em>(1) </em>4A + 1 = C + 2 + 2E

4A = C + 2E + 1

2A = C + E <em>(2) </em>Twice <em>(2):</em>

4A = 2C + 2E

Subtracting <em>(1) </em>in <em>(2)</em>

C + 2E + 1 = 2C + 2E

C + 1 = 2C

1 = C

Si 1 = C:

4A + 1 = 1 + 2 + 2E

4A = 2 + 2E <em>(1)</em>

y:

2A = 1 + E <em>(2)</em>

Twice:

4A = 2 + 2E

As <em>(1) </em>and <em>(2) </em>are the same equation:

<h3>This reaction has infinite ways to be balanced</h3><h3 />

For example:

N2O4(g) + CO → NO(g) + CO2(g)+NO2(g)

The question is incomplete, this is the complete question;

In the process of attempting to characterize a substance, a chemist makes the following observations. Which are physical properties and which are chemical properties?

(a) The substance is a silvery white, lustrous metal.

(b) The substance melts at 649 ∘C

(c) The substance boils at 1105 ∘C.

(d) The density of the substance at 20 ∘C is 1.738 g/cm³.

(e) The substance burns in air, producing an intense white light.

(f) The substance reacts with chlorine to give a brittle white solid.

(g) The substance can be pounded into thin sheets or drawn into wires.

(h) The substance is a good conductor of electricity.

Answer:

(a) Physical

(b) Physical

(c) Physical

(d) Physical

(e) Chemical

(f) Chemical

(g) Physical

(h) Physical

Explanation:

(a) The substance is a silvery white, lustrous metal - is appearance which is physical.

(b) The substance melts at 649 ∘C metling point is a physical measurement

(c) The substance boils at 1105 ∘C boiling point is a physical measurement

(d) The density of the substance at 20 ∘C is 1.738 g/cm3 how heavy a substance is,is physical.

(e) The substance burns in air, producing an intense white light. Burning is a chemical change. It is a reaction of a substance with oxygen

(f) The substance reacts with chlorine to give a brittle white solid. This is a chemical reaction as the question says.

(g) The substance can be pounded into thin sheets or drawn into wires. Ductility is a physical change, the substance remains chemically unchanged

(h) The substance is a good conductor of electricity. Any conductivity is physical, the substance remains chemically unchanged

Identify the limiting reactant when 32. 0 g hydrogen is allowed to react with 16. 0 g oxygen
Mkey [24]

Answer:

Oxygen is limiting reactant

Explanation:

2 H2  +   O2  ======> 2 H2 O

from this equation (and periodic table) you can see that

  4 gm of H combine with 32 gm O2  

     H / O  =  4/32 = 1/8

       32 /16    =  2/1    shows O is limiter

         for 32 gm H you will need 256 gm O   and you only have 16 gm
