How many grams are in calcium nitrate?
164.0878 grams
What is the molar mass of caco3?
100.0869 g/mol
What is the formula weight for calcium nitride?
148.25 g/mol
What are the charges on the calcium ion?
Since calcium lost two electrons, it has 20 protons, but only 18 electrons. This makes calcium a positive ion with a charge of 2+.
What is the charge of calcium nitride?
0
Is calcium a nitrate?
TCC’s Calcium Nitrate is an inorganic compound. Its chemical formula is Ca(NO3)2.. It is a colorless salt that absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but is found in other applications.

Why there is no back bonding in AlCl3?
3p orbitals of Al and Cl are comparatively larger. So, back bonding doesn’t occur in AlCl3. The 3p-orbitals of Al and Cl are comparatively larger in size which eventually increases the bond length and thus, it can not attain the double bond character by back bonding.
Why BCl3 is a Lewis acid?
The central atom in BCl3 (that is Boron, in trivalent state) has only six electrons around it — it is electron deficient and accepts electrons to complete it’s octet. Therefore it acts as a Lewis acid by accepting electrons.
Why BF3 exist but Bh3 not?
Bh3 molecule is an electron deficient molecule in nature since the 6 electrons are around the ‘B’ atom. Bf3 is also deficient but because of larger size of ‘F’ atom, it cannot undergo dimerization, so it exists as Bf3 with a partial negative charge in boron and partial positive charge on fluorine.
Which compound of boron does not exist in free form?
Option D is correct.
