The answer to your question is Ba(OH)₂ + 2HClO₄ ⇒ Ba(ClO₄)₂ + 2H₂O

Explanation:

Reactants

Barium hydroxide

Perchloric acid

Formula

Barium hydroxide = Ba(OH)₂

Perchloric acid = HClO₄

Equation (it is a double replacement)

Ba(OH)₂ + HClO₄ ⇒ Ba(ClO₄)₂ + H₂O

Reactants Elements Products

1 Ba 1

1 Cl 2

3 H 2

6 O 9

This reaction is unbalanced

2) Balance the chemical reaction

Ba(OH)₂ + 2HClO₄ ⇒ Ba(ClO₄)₂ + 2H₂O

Reactants Elements Products

1 Ba 1

2 Cl 2

4 H 4

10 O 10

Now the reaction is balanced

Products

Ba(ClO₄)₂ Barium perchloride

2H₂O water

Answer from: Quest

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.

Answer from: Quest

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
