In baking soda (NaHCO3) the three represents a ____
A
exponent
B
subscript
C
element
D
compound
Explanation: 

Detailed explanation-1: -Baking soda, or sodium bicarbonate, has a more complicated formula, NaHCO, . Baking soda is formed when sodium (Na), hydrogen (H), carbon (C), and oxygen (O) combine in a chemical reaction. The small number 3 in the formula is called a subscript. A subscript shows the number of atoms of an element in a compound.

Detailed explanation-2: -NaHCO3 is sodium bicarbonate or known as sodium hydrogen carbonate. Sodium bicarbonate is a white solid that appears as fine powder. It has a slightly salty, alkaline taste resembling that of sodium carbonate(washing soda). It is also known as baking soda or cooking soda.

Detailed explanation-3: -NaHCO3 (Sodium hydrogen carbonate) is a salt with basic properties. It is a combination of a strong base named NaOH (caustic soda) and a weak acid called H2CO3(carbonic acid). When both are combined, the strength of the base doesn’t neutralize fully. That’s why it makes a basic salt NaHCO3.
