Answer:
Volume of box = 125 cm³
Explanation:
Given:
Length l = 10 cm
Width b = 5 cm
Height h = 2.5 cm
Find:
Volume of box
Computation:
Volume of box = lbh
Volume of box = 10 x 5 x 2.5
Volume of box = 125 cm³
Answer:
The correct answer is a catalyst.
Explanation:
Catalysts are substances that can be added to a reaction to increase the reaction rate without being consumed in the process.
They generally work by reducing the energy of the transition state and thus decreasing the activation energy or changing the mechanism of the reaction. This also changes the nature (and energy) of the transition state. Biochemical processes, such as glucose oxidation, rely heavily on enzymes, proteins that act as catalysts.
Other common types of catalysts are acid-base catalysts and heterogeneous or surface catalysts.
Have a nice day!
Answer is: a <span>theoretical definition. But this definition is wrong because oxygen has atomic number 8 and atomic weight 16.
