Answer: Law of conservation of mass explains these observations.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
Mass of reactants= mass of Mg+ mass of 
= 48 g + 32 g = 80 g
Mass of products = mass of 
= 80 g
Thus mass of reactants is equal to mass of products, thus law of conservation of mass is obeyed.
The lower the frequncy the longer the wavelength the longer the wavelength whoch would probably give you more energy.
if im incorrect im truly sorry
The temperature at which the oven it set it should be.
Answer:
I think that it is II and IV.
I'm not positive so don't count on it, but i'm bout to be in 11th grade and I remember my chemistry teacher showing us this video so there is a video on you tube where he explains in.
Explanation:
I'm sorry if this is useless, but lemme know what you get for the answer. Good Luck:)
Potential energy is stored energy. Kinetic energy involves movement.
If a ball is on the top of a hill, it has the most potential energy on the very top of the hill. The kinetic energy is also 0 at this point.
If the ball rolls down the hill, potential energy decreases while kinetic increases.
