What is the strongest type of solid?
Covalent bonds are very strong, so covalent network solids typically have the highest melting points out of all four types of solids. They usually don’t conduct electricity because valence electrons are localized within covalent bonds.

What solid does Zn form?
Zn is a d-block element, so it is a metallic solid.
Is NaOH a solid or liquid?
At room temperature, sodium hydroxide is a white, odorless solid. Liquid sodium hydroxide is colorless and has no odor. It can react violently with strong acids and with water. Sodium hydroxide is corrosive.
How much NaOH is dangerous?
NIOSH: The recommended airborne exposure limit (REL) is 2 mg/m3, which should not be exceeded at any time. ACGIH: The threshold limit value (TLV) is 2 mg/m3, which should not be exceeded at any time.
What is 1M NaOH?
A molar solution implies concentration in terms of moles/liter. One molar (I M) solution means one mole of a substance (solute) per liter of solution. Thus 40 grams of NaOH equals one mole of NaOH, and a 1 molar solution of NaOH will contain 40 grams of NaOH chemical.
How do you calculate 1M NaOH?
molarity = no. of moles of solute / 1 liter . * one moles of sodium hydroxide = 40 gm of sodium hydroxide. so we can said ; if want prepare 1 molar NaOH solution then we need 40 gm NaOH dissolve in one liter of water so it became one 1 molar NaOH solution.
How do you make 2 m NaOH?
And 500 mL of 2M NaOH solution contains 80.02g NaOH=40.0 g of NaOH . So, If we mix 40.0 g of NaOH with enough distilled water to make 500 mL, we will get a 2.00 M NaOH solution.
