zavuch27 [327]

Answer:

6 C(s) +  3 O₂(g) + 2 Fe₂O₃(s) →  4 Fe(s) + 6 CO₂(g)

Explanation:

Iron can be formed in two steps.

Step 1: 2 C(s) + O₂(g) → 2 CO(g)

Step 2: Fe₂O₃(s) + 3 CO(g) → 2 Fe(s) + 3 CO₂(g)

In order to get the net chemical equation, we will multiply the first step by 3, the second step by 2, and then add them.

6 C(s) +  3 O₂(g) → 6 CO(g)

+

2 Fe₂O₃(s) + 6 CO(g) → 4 Fe(s) + 6 CO₂(g)

--------------------------------------------------------------------------------------------------

6 C(s) +  3 O₂(g) + 2 Fe₂O₃(s) + 6 CO(g) → 6 CO(g) + 4 Fe(s) + 6 CO₂(g)

6 C(s) +  3 O₂(g) + 2 Fe₂O₃(s) →  4 Fe(s) + 6 CO₂(g)

Evaluate each scenario to determine whether it represents a chemical reaction.
vova2212 [387]

Explanation:

A chemical reaction is one in which a chemical change occurs.

During a chemical change;

  • The process is irreversible
  • New kinds of matter produced
  • There is a change in mass

Based on these premise;

 Baking  cake batter is a chemical reaction because you cannot reverse the process

  Shredding a paper is not a chemical reaction because no new kind of matter is produced.

  Twisting of a metal wire is not a chemical reaction

   Yellowing of newspaper in sunlight is a chemical change. The process cannot be reversed

According to the collision theory, what happens in a collision without sufficient energy or correct orientation
ohaa [14]
Hi!

In collision theory, for a chemical reaction to occur - there must be <em>sufficient </em>energy to break down chemical bonds.
 
We call this the activation energy, as it's the energy needed to <em>activate </em>a chemical reaction! 

Hopefully, this helps! =)
