Base unit is the fundamental unit of measurement that is not mutually dependent. The seven base units are,
Length - meter
Mass- kilogram
Time - second
Temperature - Kelvin
Current - Ampere
Luminous intensity - Candela
Amount of matter - mole
Derived units are derived from the seven base units. Like the area (square meters) is the square of length (meters), volume is the cube of length.
Answer:
products
Explanation:
In chemistry, chemical reactions is the combination of two or more substances to yield other substances. The substances that react is called REACTANTS while the substances formed after the reaction is called PRODUCTS.
According to this question, a mixture of oxygen and hydrogen is ignited in a test tube as follows:
Hydrogen + Oxygen → Water + Energy
In this reaction, the substances being combined (usually found on the left side of the equation) are hydrogen and oxygen. Hence, oxygen and hydrogen are REACTANTS. Also, the substances produced as a result of the reaction is water (H2O). The PRODUCTS of the reaction is WATER.
