Which of the following equations are balanced?

Chemistry
1 answer:
Debora [2.8K]2 years ago
7 0

Answer:

The only balanced equation is:

2KClO₃ → 2KCl + 3O₂

Explanation:

In reactant side: 6 atoms of O, 2 atoms of Cl and 2 atoms of K

In product side: 2 atoms of K and 2 atoms of Cl + 6 atoms of O

CO + 3H₂ → CH₃OH

In reactant side: 1 C, 1 O and 6 H

In product side: 1 C, 4 H and 1 O

PCl₃ + 2Cl₂ → PCl₅

In reactant side: 1 P, 7 Cl

In product side. 1 P, 5 Cl

Mg + N₂ → Mg₃N₂

In reactant side 1 Mg and 2 N

In product side 3 Mg and 2 N

Gemiola [76]

Exchange rate is 2 guilders for every 3 florins

The conversion factor will be

2 guilders / 3 florins = 3 florins / 2 guilders = 1

so if we wish to convert 17 guilders to florins we will use following conversion factor

3 florins / 2 guilders = B / C

D = 17guilders X 3 florins / 2 guilders = 25.5 florins

What factors could have affected your results?
AleksandrR [38]

Answer:

See below  

Step-by-step explanation:

heat gained by metal + heat lost by water = 0

           m₁C₁ΔT₁           +         m₂C₂ΔT₂         = 0

C₁ = -(m₂C₂ΔT₂)/(m₁ΔT₁)

The factors determining C₁ are

  • mass of water
  • temperature change of water (T_f - Ti)
  • mass of metal
  • temperature change of metal (T_f - Ti)

Any factor that makes the numerator higher or the denominator lower than what you thought, will give a calculated C₁ that is too high (and vice versa).

The major sources of uncertainty are probably in determining the temperatures, especially the initial and final temperatures of the metal. However, you will have to decide what the principal factors were in your experiment.

For example, did the metal have a chance to cool during the transfer to the calorimeter? How easy was it to determine the equilibrium temperature, etc?

Factors Affecting the Calculation of Specific Heat Capacity

<u>          Too Low                 </u>              <u>      Too high                   </u>              

Water                                             Water

    Mass less than thought                Mass more than thought

    Ti lower                                         Ti higher

    T_f higher                                       T_f lower

Metal                                              Metal

    Mass more than thought             Mass less than thought

    Ti higher                                       Ti lower
