Answer:
The atomic number of the sodium atom is 11. The atomic mass number can be estimated by rounding the atomic mass to 23.
Explanation:
The atomic number of the sodium atom is 11. The atomic mass number can be estimated by rounding the atomic mass to 23.
Taking into account the definition of molarity, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
<h3>This case</h3>
In this case, you have:
- number of moles= 30 moles
- volume= 0.80 L
Replacing in the definition of molarity:
Solving:
<u><em>Molarity= 37.5 </em></u><em />
Finally, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 .

I don't know because I'm in 5th grade but I will try
no because the temperature is changing from cold to hot to hotter hope I helped
The type of energy do chemical bonds have, and the type of energy is it converted to during chemical reactions are that chemical bonds have potential energy, which is converted to heat energy during chemical reactions.
Answer: Option D
Explanation:
The chemical molecules which are bonded by atoms to form such molecule in its stable form consists of chemical potential energy. The potential energy is form of energy which is possessed by the bond, atom or molecule in its non excited or stable state.
As the chemical bonds are stable in nature, they consist of Chemical potential energy. The potential energy of bond converts into heat energy as the bond on breakage either takes up energy to break the bond or releases the heat to break the bond, during the chemical reactions occurring.
