First let us calculate the initial molarity of the 2.45 L
of solution. Molar mass = 171.34 g/mol
<span>moles Ba(OH)2 = 74.28 g * (1 mole / 171.34 g) = 0.4335 moles</span>
Molarity (M1) = 0.4335 moles / 2.45 L = 0.177 M
Now using the formula M1V1 = M2V2, we can calculate how
much to dilute (V1):
0.177 * V1 = 0.1 * 1
V1 = 0.56 L
<span>Therefore 0.56 L of the initial solution must be diluted
to 1 L to make 0.1 M</span>
Answer: An ion with fewer electrons than its neutral atom is called a(n) cation. The charge of an ion with more electrons than its neutral atom is. negative.Name an ionic compound by the cation followed by the anion. ... Covalent compounds are formed when two or more nonmetal atoms bond by sharing valence electrons. Valence electrons are the outermost electrons of an atom.
Explanation:
6.02 x 10^23, basically a mole since the molar mass of carbon is 12
Answer:
Cold Shuts. Cold shuts are one of the most common defects found in materials sent for electroplating.
Pitting

Dull and Hazy Deposits in Plating.
Explanation:
When ammonia is reacted with HCl it abstracts proton from acid and forms Ammonium Ion and Chloride Ion.
NH₃ + HCl → ⁺NH₄ + Cl⁻ (simply Written NH₄Cl)
Structure,
The structure of Ammonium Chloride is among those structures which contains all three types of bonding's, i.e.
Ionic Bond
Covalent Bond
Coordinate Covalent Bond
Three Hydrogen atoms previously bonded with Nitrogen are covalent in nature. The new incoming proton from HCl forms co-ordinate covalent bond with Nitrogen and Chloride Ion containing negative charge make Ionic Bond with the positive Ammonium Ion. In question, if the line between Nitrogen and Chlorine atom is assumed covalent then it is incorrect. Structure is shown below,
