Answer:
Ideal Solution: An ideal solution is a solution where interactions between molecules are identical between all the molecules in the solution. Non ideal Solution: A non ideal solution is a solution that has differences in the interactions between molecules of different components in the solution.
Explanation:
The valence electrons of an element is usually determined by its atomic number. The valence elctrons are the electrons that have the highest energy level.
Fluorine has 7 valence electrons in the ground state.
This is actually incorrect, the distance as stated above either from trough to trough or from crest to crest within a corresponding wave, would be referred or called as the wavelength of the given wave.
Answer:
0.142 M
Explanation:
Let's consider the neutralization reaction between calcium hydroxide and hydrochloric acid.
Ca(OH)₂ + 2 HCl → CaCl₂ + 2 H₂O
25.8 mL of 0.183 M HCl are used. The reacting moles are:
0.0258 L × 0.183 mol/L = 4.72 × 10⁻³ mol
The molar ratio of Ca(OH)₂ to HCl is 1:2. The reacting moles of Ca(OH)₂ are 1/2 × 4.72 × 10⁻³ mol = 2.36 × 10⁻³ mol
2.36 × 10⁻³ moles of Ca(OH)₂ are contained in 16.6 mL. The molarity of Ca(OH)₂ is:
M = 2.36 × 10⁻³ mol/0.0166 L = 0.142 M
