Answer is 2KClO3 3O2 + 2KCl
Answer:
130ml of HCl(36%) in 4.90L solution => pH = 1.50
Explanation:
Need 4.90L of HCl(aq) solution with pH = 1.5.
Given pH = 1.5 => [H⁺] = 10⁻¹·⁵M = 0.032M in H⁺
[HCl(36%)] ≅ 12M in HCl
(M·V)concentrate = (M·V)diluted
12M·V(conc) = 0.032M·4.91L
=> V(conc) needed = [(0.032)(4.91)/12]Liters = 0.0130Liters or 130 ml.
Mixing Caution => Add 131 ml of HCl(36%) into a small quantity of water (~500ml) then dilute to the mark.
Answer:
A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.

Explanation:
An equation is said to be balanced when the number of atoms on both reactant and product side are equal in number.
Whereas an equation where electrolytes in an aqueous solution are represented as dissociated ions is known as an ionic equation.
For example,
can be represented in ionic form as follows.

Now, cancelling the common ions present on both sides of the equation. The resulting, ionic equation will be as follows.
