The balanced molecular equation for the reaction between solid sodium bicarbonate and hydrochloric acid to produce carbon dioxide gas, water and aqueous solution of sodium chloride is
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The balanced equation can be written as follow:
Sodium bicarbonate => NaHCO₃
Hydrochloric acid => HCl
Carbon dioxide => CO₂
Water => H₂O
Sodium chloride => NaCl
Sodium bicarbonate + Hydrochloric acid —> Carbon dioxide + Water + Sodium chloride
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The equation above is balanced since the number of the different atoms of the elements present on both sides are equal.

Answer : The balanced two-half reactions will be,
Oxidation half reaction :
Reduction half reaction :
Explanation :
Voltaic cell : It is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy. It is also known as the galvanic cell or electrochemical cell.
In the voltaic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.
The given redox reaction is:
The balanced two-half reactions will be,
Oxidation half reaction :
Reduction half reaction :
In the amtmosphere this water vapor cools and turns back to liquid for forming clouds
this process is called condensation. When it cant hold on much longer it will turn into rain or snow.
Answer: I think it’s B. Because as you can see from the picture there are layers
Explanation:
I think but just in case ask for a second opinion
<u>Answer:</u> The hydrogen ion concentration in apple juice is
<u>Explanation:</u>
pH is defined as negative logarithm of hydrogen ion concentration. It is basically defined as the power of hydrogen ions in a solution.
Mathematically,
We are given:
Putting values in above equation, we get:
Hence, the hydrogen ion concentration in apple juice is
