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.
Answer:
The answer is
<h2>110.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of rock = 5.8 g/mL
volume = final volume of water - initial volume of water
volume = 12.4 - 10.5 = 1.9 mL
The mass of the rock is
mass = 5.8 × 1.9
We have the final answer as
<h3>110.2 g</h3>
Hope this helps you
