What is the chemical formula formula for rubidium carbonate?
Rb2CO3 for rubidium carbonate
A 6.88 g sample of the hydrated crystal Rb2CO3 xH2O is heated until all the water is removed The remaining solid weighs 5.24 g Calculate the formula of the hydrated crystal?
Okay, the anhydrate that weighs 5.24g (after heating) is pure rubidium carbonate (Rb2CO3) so the 6.88g represents the molar mass of the hydrated crystal. Set up an algebraic direct proportion: 6.88/x = 5.24/(molar mass of Rb2CO3) which is 231g/mol. Solve for x to get 303.3. Subtract out the anhydrate mass: 303.3 - 231 = 72.3. Now divide that number by water's molar mass, which is 18g/mol: 72.3/18 = 4, so the formula of the hydrate crystal is Rb2CO3-4H2O.

Does methanol have ionic or covalent bond?
The Answer is... covalent bonds
Is c2h2 an ionic or covalent?
What is c2h2??? If you mean 'C2H2' , then this is ETH**Y**NE It is an AlkYne , neither an Alkane, nor an Alkene There is a TRIPLE bond between the two carbons. Structurally, H-C///C-H It archaic name is acetylene, as used in oxy-acetylene burners. NB Note the one letter 'Y' difference in the spelling. NNB Single letter elemental symbols are ALWAYS written as a CAPITAL letter. Hence carbon is 'C' not 'c' and hydrogen is 'H' not 'h' This is the agreed international standard, and as shown in the Periodic Table.
Is Hydrogen Sulphide is covalent or ionic compound?
Hydrogen Sulphide is covalent.They are both non-metals.
