Answer:
<h3>Avogadro's hypothesis states that two samples of gas of equal volume, at the same temperature and pressure, contain the same number of molecules. Avogadro's hypothesis allows chemists to predict the behavior of ideal gasses.</h3>
hope it helps
Answer:
This is an example of Atom
Answer:
497 K
Explanation:
Assuming that the volume of the balloon (and so, the gas) remains constant, we can solve the problem by using the pressure's Law:
"When a constant mass of an ideal gas is kept at constant volume, the pressure of the gas is directly proportional to its absolute temperature"
Mathematically:
where
p is the pressure of the gas
T is the absolute temperature
The equation can also be rewritten as
where:
is the initial pressure of the gas
is the initial temperature of the gas
is the final pressure of the gas
Solving for T2, we find the final temperature:
Answer;
-(3) an atom in an excited state
Explanation;
-An electron in a sodium atom gains enough energy to move from the second shell to the third shell. The sodium atom becomes an atom in an excited state.
-Ground state is the lowest allowable energy state of an atom. When electrons are subjected to stimuli like heat, light or electricity an electron may jump to a higher energy level, which is the excited state. Excitation is the elevation in energy level above the baseline energy state.
D is the answer!!!!!!!!!!!!!!!!
