Question

Допишіть рівняння реакцій: NaCl + H2CO3 = CaCl + HNO3 = BaCO3 + H2SO4 =

Answer 1

NaCl + H2CO3 =Реакция не идет.Эти два соединения непосредственно друг с другом не реагируют

CaCl2 + 2HNO3 → Ca(NO3)2 + 2HCl

Answer 2

Balancing Chemical Equations

When balancing chemical equations, it's important to ensure that the same number of each type of atom is present on both sides of the equation. Let's balance the given chemical equations:

1. NaCl + H2CO3 = The reaction between sodium chloride (NaCl) and carbonic acid (H2CO3) can be represented by the following balanced chemical equation: ``` NaCl + H2CO3 = NaHCO3 + HCl ```

This balanced equation ensures that the number of atoms of each element is the same on both sides of the equation.

2. CaCl2 + HNO3 = The reaction between calcium chloride (CaCl2) and nitric acid (HNO3) can be represented by the following balanced chemical equation: ``` CaCl2 + 2HNO3 = Ca(NO3)2 + 2HCl ```

This balanced equation ensures that the number of atoms of each element is the same on both sides of the equation.

3. BaCO3 + H2SO4 = The reaction between barium carbonate (BaCO3) and sulfuric acid (H2SO4) can be represented by the following balanced chemical equation: ``` BaCO3 + H2SO4 = BaSO4 + H2CO3 ```

This balanced equation ensures that the number of atoms of each element is the same on both sides of the equation.

Balancing chemical equations is essential for understanding chemical reactions and ensuring that the law of conservation of mass is upheld. If you have any more questions about chemistry or balancing chemical equations, feel free to ask!
