Hi my dear friend,
How to find mass of hydrate?
Divide the mass of your anhydrous (heated) salt sample by the molar mass of the anhydrous compound to get the number of moles of compound present. In our example, 16 grams / 160 grams per mole = 0.1 moles. Divide the mass of water lost when you heated the salt by the molar mass of water, roughly 18 grams per mole.
~Thank you
Answer:
So if we need to react with 88 gm. of copper 2 then at least 3-4 liters.
Explanation:
Answer:
U should do like this... It's true
Answer:
Covalent compounds use prefixes for naming because it specifies the number of atoms as more than one atom of each element is present.
Explanation:
Covalent compounds use prefixes for naming because it specifies the number of atoms as more than one atom of each element is present.
For example: "mono" indicates 1 atom, "di" indicates two atoms, "Hexa" indicates 6 atoms, "octa" indicates eight atoms.
When naming binary ionic compounds, the cation is named first, then the nonmetal anion is named.
Answer:
The correct option is: b. the elements in the material are well apart (in different sides) in the periodic table
Explanation:
Ionic bond is a type of chemical bonding that is formed by the transfer of electrons from one atom to another. It is formed between atoms having large electronegativity difference.
The more electronegative atom accepts electrons and becomes a negatively charged anion. Whereas, the less electronegative atom loses electrons and becomes a positively charged cation.
<u>Simply, an ionic bond is formed when the electrons are transferred from a metal to a non-metal, which are present on different sides of the periodic table.</u>
