H2(g) + Co(g) _CH3OH<br> balance the equation <br>​
Tom [10]

Answer:

CO + 2H2 = CH3OH

Explanation:

1. Label Each Compound With a Variable

  aCO + bH2 = cCH3OH

2. Create a System of Equations, One Per Element

  C: 1a + 0b = 1c

  O: 1a + 0b = 1c

  H: 0a + 2b = 4c

3. Solve For All Variables (using substitution, gauss elimination, or a calculator)

  a = 1

  b = 2

  c = 1

4. Substitute Coefficients and Verify Result

  CO + 2H2 = CH3OH

      L R

  C: 1 1 ✔️

  O: 1 1 ✔️

  H: 4 4 ✔️

Answer:

D. C₄H₁₀ and C₂H₅

<h2>What is a empirical formula?</h2>

A chemical formula indicating the elements of a compound and their relative proportions, as (CH₂O)n.

Since an empirical formula indicates the ratio (proportions) of the elements in the compound, it can be used, along with the molar weight of the compound, to determine the molecular formula.

The empirical formula provides the smallest whole-number ratio among elements or compounds within a molecular compound. A compound is a chemical formed from atoms of different chemical elements.

Hence, Option D is correct.
