Ammonia is the most basic and has the highest OH- concentration since it has the highest pH.
Answer:
it decreases the amplitude of the wave as it propagates
Explanation:
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 internal energy of the ideal gas is zero
The change in internal energy for an isothermal process is zero.
An ideal gas has no interactions between particles, therefore no intermolecular forces.
pressure change at constant temperature does not change the internal energy.
Adiabatic throttling expansion has less work done and lower heat flow.
That lower the internal energy.
The temperature decreases during the adiabatic expansion
Hence the internal energy of the ideal gas is zero
