Answer:
A. It shows the same number of atoms of each element on both sides of the equation.
Explanation:
A balanced chemical equation demonstrates the conservation of matter by showing the number of atoms of each element on both sides of the equation or expression.
According to the law of conservation of matter, matter is neither created nor destroyed in the course of a chemical reaction but atoms are rearranged.
- Based on this premise, the number of atoms or moles on both sides of the expression must be equal.
- If there are 3 atoms of carbon on one side, the product must also reflect 3 atoms of carbon.
First Rusting is slow oxidation of iron into iron oxide using H2O and oxygen in atmosphere which is a chemical reaction.
burning is also a oxidation but kinda fast using oxygen in atmosphere to oxidize the hydrocarbon(paraffin wax) in candle to give heat and CO2.
So they are both chemical reactions which happens at different rate.
Answer:
The Concrete has a lower specific heat.
Explanation:
Plane is the right answer I thinkkkkk
