Define stoichiometry as a branch of chemistry
Stoichiometry is a branch of chemistry that deals with the quantitative relationships between reactants and their products within chemical reactions
What is the first law of thermodynamics
The first law of thermodynamics (Or otherwise known as the law of conservation of energy) states that energy cannot be created nor destroyed
Balance the following equation

What is avogadro's number

What is the double-slit experiment used for in quantum physics
To demonstrate how light acts as both a particle and wave depending on whether we're observing it or not
What is the result in differentiating a quadratic displacement-time graph, and then the result of differentiating it again
After differentiating it, you will be left with a linear equation which represents the velocity-time graph where Y = mx + c (Y - Time, X - Velocity)
Differentiate it one more time and you are left with a constant, that being the acceleration. (Slope of the velocity time graph is equal to the acceleration of the object)
