<h3>Further explanation</h3>
Given
Rust reaction
Required
Balanced equation
Solution
Reaction
Fe + O₂⇒ 2Fe₂O₃
For a simple equation where one of the reaction coefficients is known, we can immediately add the corresponding coefficient using the principle that the number of atoms of <em>the components in the reactants and products is the same.
</em>
In the above reaction :
Fe, left=1, right = 4, so coefficient in the left=4
O, left=2, right = 6, so coefficient in the left=3
Answer: placing coefficients
Explanation: In a balanced chemical equation, the total number of atoms of each element present is the same on both sides of the equation. Stoichiometric coefficients are the coefficients required to balance a chemical equation. These are important because they relate the amounts of reactants used and products formed.
the reaction is HF + NaOH which leads to NaF
Answer:
What do cuticles do for land plants that was not necessary for ancestors that lived in water? Cuticles help prevent water loss. ... The next groups of land plants to evolve were ferns, which could grow bigger and taller because they could transport water and food.
