Question

directions: check to see if the following equations are balanced or not then color the picture accordingly.
equations

1. 2fe + 3cl₂→2fecl₃
2. 4fe + 3o₂→2fe₂o₃
3. c₂h₄+o₂→co₂h₂o
4. ch + co→c₂+ho
5. 4h₂sicl₂+4h₂o→h₈si₄o₄+8hcl
6. c₇h₁₆+o2→co₂+h₂o
7. hsicl₃+h₂o→h₁₀si₁₀o₁₅+hcl

show your work below: (this is what you will be graded on😊) *count the number of atoms for each element on both sides of the reaction, they need to be equal - adjust with coefficients 2h₂o = 4h 2o

Explanation:

Step1: Analyze equation 1

On left - hand side: 2 Fe atoms and 6 Cl atoms. On right - hand side: 2 Fe atoms and 6 Cl atoms. So it is balanced.

Step2: Analyze equation 2

On left - hand side: 4 Fe atoms and 6 O atoms. On right - hand side: 4 Fe atoms and 6 O atoms. So it is balanced.

Step3: Analyze equation 3

On left - hand side: 2 C atoms, 4 H atoms, 2 O atoms. On right - hand side: 1 C atom, 2 H atoms, 3 O atoms. So it is not balanced.

Step4: Analyze equation 4

On left - hand side: 2 C atoms, 1 H atom, 1 O atom. On right - hand side: 2 C atoms, 1 H atom, 1 O atom. But CH is not a correct chemical formula. So it is not balanced.

Step5: Analyze equation 5

On left - hand side: 4 Si atoms, 16 H atoms, 8 Cl atoms, 4 O atoms. On right - hand side: 4 Si atoms, 16 H atoms, 8 Cl atoms, 4 O atoms. So it is balanced.

Step6: Analyze equation 6

On left - hand side: 7 C atoms, 16 H atoms, 2 O atoms. On right - hand side: 1 C atom, 2 H atoms, 3 O atoms. So it is not balanced.

Step7: Analyze equation 7

On left - hand side: 1 Si atom, 3 Cl atoms, 2 H atoms, 1 O atom. On right - hand side: 10 Si atoms, 15 O atoms, 10 H atoms, 1 Cl atom. So it is not balanced.
