Answer:

D. All of these.

Explanation:

For an equation to be balanced the number of atoms of each kind in the reactants and the products should be the same.

Then from this equation, CO  is a product.

Last, two carbon atoms undergo reaction with the oxygen molecule for complete reaction to occur. Each atom combines with one oxygen atom.

<u>Answer:</u>

<em>D) All of these</em>

<em></em>

<u>Explanation:</u>

2 C(s) + O_2 (g) > 2 CO(g)

Reactant side (Left side)  Element     Product side (Right side)

2                                                   C                                      2

2                                                   O                                      2

Balanced!!!

Balancing is making the number of atoms of each element same on both the sides  (reactant and product side).

To find the number of atoms of each element we multiply coefficient × subscript  

For example 5 Ca_1 Cl_2 contains  

5 × 1 = 5 ,Ca atoms and

5 × 2 = 10, Cl atoms  

If there is a bracket in the chemical formula

For example 3Ca_3 (P_1 O_4 )_2 we multiply coefficient × subscript × number outside the bracket.......... to find the number of atoms  (Please note: 3 is the coefficient, and if there is no number given then 1 will be the coefficient )

So

3 × 3 = 9 , Ca atoms  

3 × 1 × 2 = 6, P atoms  

3 × 4 × 2 = 24, O atoms are present.

Colloid

Explanation:

A lotion of this type is a typical colloid mixture.

  • A colloid is a homogeneous mixtures of two phases.
  • The dispersed phase and the dispersion medium.
  • Water is the dispersion medium and oil is the dispersed phase.

They have the following properties:

  • Liquid dispersed phase and liquid dispersion medium forms an emulsion and a lotion of this type is an example.
  • The particles are larger than those found in solutions.
  • The particles pass through ordinary filter paper.
  • They may be cloudy or clear .
