Because it has fixed boiling point up to 100 C
Hey there!
Molar mass NaCl = 58.44 g/mol
Number of moles
n = mass of solute / molar mass
n = 59.76 / 58.44
n = 1.0225 moles of NaCl
Volume in liters:
270 mL / 1000 => 0.27 L
Therefore:
M = number of moles / volume ( L )
M = 1.0225 / 0.27
= 3.78 M
Hope that helps!
Electrons that have the highest energy are valence electrons. This is because the electron(s) on the outer shell are further away from the attractive force of the nucleus (remember, the nucleus is positively charged as protons are positive and neutrons are neutral, and electrons are negatively charged). This means that electrons on the outer shell are easier to remove, and are more reactive.
Answer:
The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
Answer:
The molarity of products is divided by the molarity of reactants.
