Answer:
Me too
Explanation:
I dont know why but me too
Atoms will combine with each in order to become more chemically stable by sharing electron and Compounds are formed between two atoms that have chemical bond that links them together.
In order for molecules and crystals to form, atoms or ions must maintain a long-lasting attraction to one another. Ionic and covalent bonds are formed by the sharing of electrons, while ionic bonds are formed by the electrostatic attraction between two oppositely charged ions. There are "strong bonds" or "primary bonds" like covalent, ionic, and metallic bonds as well as "weak bonds" or "secondary bonds" like dipole-dipole interactions, the London dispersion force, and hydrogen bonding. The strength of chemical bonds varies greatly. By sharing or transferring electrons between the involved atoms, strong chemical bonds are created.
Since opposing electric charges attract, the positively charged protons inside a nucleus and the negatively charged electrons that surround it are drawn to one another. Placing an electron between them

the roman numeral tells you that the metal is a transition metals. transition metals have more than one oxidation state.
Answer: 1.85M
Explanation:
Sodium hydroxide has a chemical formula of NaOH
Given that,
Amount of moles of NaOH (n) = ?
Mass of NaOH in grams = 63g
For molar mass of NaOH, use the molar masses:
Sodium, Na = 23g;
Oxygen, O = 16g;
Hydrogen, H = 1g
NaOH = (23g + 16g + 1g)
= 40g/mol
Since, amount of moles = mass in grams / molar mass
n = 63g / 40.0g/mol
n = 1.575 mole
Volume of NaOH solution (v) = 850mL
[Convert 850mL to liters
If 1000mL = 1L
850mL = 850/1000 = 0.85L]
Concentration of NaOH solution (c) = ?
Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence
c = n / v
c = 1.575 mole / 0.85L
c = 1.85M [1.85M is the concentration in moles per litres which is also known as molarity]
Thus, the molarity of the solution is 1.85M
