Answer:
It breaks down into multiple elements
Explanation:
A decomposition reaction is a type of chemical reaction in witch a single compound breaks down into two or more elements or new compounds. These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compound
Answer:
D. A pond freezing over is not a chemical reaction, it is a physical reaction.
Answer:
[H₂O] > [H₃O⁺] ≳ [Cl⁻] > [OH⁻] > [HCl]
Explanation:
HCl + H₂O ⟶ H₃O⁺ + Cl⁻
HCl dissociates completely in solution.
[HCl] = 0 mol·L⁻¹
[H₃O⁺] = 1.0 × 10⁻⁶ mol·L⁻¹
[Cl⁻] = 1.0 × 10⁻⁶ mol·L⁻¹
[H₃O⁺] is slightly greater than [Cl⁻] because the autoionization of water also creates some hydronium ion.
1 L of water has a mass of 1000 g.
∴ [H₂O] = 55.49 mol·L⁻¹
∴ [H₂O] > [H₃O⁺] ≳ [Cl⁻] > [OH⁻] > [HCl]
55.5 10⁻⁶ 10⁻⁶ 10⁻⁸ 0
Answer:
b, pure.
Explanation:
an element is a pure substance and it cannot be broken down hope this helped :)
Answer :
X =
Y =
Explanation :
Balanced chemical equation : It is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
The given chemical equation is:
As we know that when aluminum hydroxide react with sulfuric acid then it gives aluminum sulfate and water as product.
The balanced chemical reaction will be:
Thus, X is and Y is
