2NaOH+CuCl2->Cu(OH)2+2NaCl
This is a balanced chemical equation.
The given chemical equation represents a reaction between sodium hydroxide (NaOH) and copper(II) chloride (CuCl2) to form copper(II) hydroxide (Cu(OH)2) and sodium chloride (NaCl). Here's a step-by-step breakdown of the chemical equation:
Step 1: Identify the reactants and products:
- Reactants: sodium hydroxide (NaOH) and copper(II) chloride (CuCl2)
- Products: copper(II) hydroxide (Cu(OH)2) and sodium chloride (NaCl)
Step 2: Write the balanced chemical equation:
2 NaOH + CuCl2 → Cu(OH)2 + 2 NaCl
Step 3: Determine the number of atoms for each element on both sides of the equation:
On the left side:
- Sodium (Na): 2
- Hydrogen (H): 2
- Oxygen (O): 2
- Copper (Cu): 1
- Chlorine (Cl): 2
On the right side:
- Copper (Cu): 1
- Hydrogen (H): 2
- Oxygen (O): 2
- Sodium (Na): 2
- Chlorine (Cl): 2
Step 4: Balance the equation by adjusting the coefficients:
The equation is already balanced, as the number of atoms for each element is the same on both sides of the equation.
Step 5: Interpret the balanced equation:
The balanced equation shows that when 2 moles of sodium hydroxide react with 1 mole of copper(II) chloride, they produce 1 mole of copper(II) hydroxide and 2 moles of sodium chloride.
Please note that in reality, copper(II) hydroxide is not very stable and often decomposes further to form copper(II) oxide (CuO) and water (H2O).
The equation you have given represents a chemical reaction between sodium hydroxide (NaOH) and copper(II) chloride (CuCl2). The reaction produces copper(II) hydroxide (Cu(OH)2) and sodium chloride (NaCl).
To balance the equation, you need to ensure that the same number of atoms of each element is present on both sides of the equation. Here's the balanced equation:
2NaOH + CuCl2 -> Cu(OH)2 + 2NaCl
Now, let's break down the reaction and understand what is happening:
2 molecules of sodium hydroxide (NaOH) combine with 1 molecule of copper(II) chloride (CuCl2). As a result, 1 molecule of copper(II) hydroxide (Cu(OH)2) and 2 molecules of sodium chloride (NaCl) are formed.
To determine the products of a chemical reaction like this, you need to refer to the charges of the individual ions involved. Sodium (Na) typically has a charge of +1, hydroxide (OH) has a charge of -1, copper (Cu) can have a charge of +2, and chloride (Cl) has a charge of -1.
In the reactants, the NaOH molecule contains a sodium ion (Na+) and a hydroxide ion (OH-), while CuCl2 consists of one copper ion (Cu2+) and two chloride ions (Cl-).
When sodium hydroxide and copper(II) chloride react, the sodium cations (Na+) combine with chloride anions (Cl-) to form sodium chloride (NaCl), while the copper(II) cation (Cu2+) combines with hydroxide anions (OH-) to form copper(II) hydroxide (Cu(OH)2).
Overall, the reaction follows the law of conservation of mass and charge, with the number and type of atoms and ions being conserved throughout.
It's always important to balance chemical equations to accurately represent the reactants and products involved in a reaction. Balancing equations can be done by adjusting the coefficients (numbers in front of each compound or molecule) until the numbers of atoms on both sides of the equation are equal.
