A. Aluminum (Al) has a charge of +3 Hydroxide (OH) has a charge of -1 Phosphate (PO4) has a charge of -3 Charges must match when bonding. Because Al and PO4 both have a charge of 3, neither has to be multiplied Al has a charge of +3 and hydroxide has a charge of -1 If you multiply hydroxide by 3, it now has a charge of -3 which can then be bonded with Aluminum with its charge of +3

A. Common name? Those are pretty much it. Carbonic acid happens to be carbon dioxide dissolved in water, but I don't think that counts. The chemical name for fool's gold is iron disulfide, FeS2. The chemical name for bleach is sodium hypochlorite, NaOCl. The chemical name for aspirin is acetylsalicylic acid, like you said, formula C9H8O4 or structurally C6H4(OCOCH3)COOH. Methanol, CH3OH, or wood alcohol or methyl alcohol, is used as an antifreeze, solvent, or fuel. Milk of magnesia (not magnesium) is a laxative used to treat constipation and can also be used to relieve heartburn and indigestion. I know you've seen the commercials for this stuff. Carbonic acid is, again, carbon dioxide in water, which is basically soda.

how do i do this? On chemisty compounds.?
Q. okay this isnt homework its a test that was already corrected i want to make sure he marked them right , if you want i can send you a scanned version if you dojnt believe me : ) Write the chemical formula for each compound. and if its ionic or covalent a) aluminum Chloride b) Magnesium chloride Write the formula's for these compounds containing Polyatomic Ions. a) silver nitrate b) zinc hydroxide c) iron (II) nitrate d) Lithium hydroxide e) Hydrogen Phosphate Write the Chemical formual and if they are ionic or covalent a) Beryllium flouride b) sodium nitride c) Diphosphorus pentaoxide d) Aluminum Chloride e) lithium oxide f) Potassium Nitride g) calcium flouride could you explain one of each so i can learn how to do it… [cont.]

please help me with chemical equations hurry need help?
Q. Copper(ll) carbonate(s)--->[little heat symbol under arrow] Copper(s) + silver nitrate(aq)---> Aluminum(s) + hydrochloric acid(aq)---> Lead(ll) nitrate(aq) + potassium chromate(aq)---> iron(lll) chloride(aq) + sodium hydroxide(aq) please i am not cheating i have the answers i just wanna make sure please provide the products and the formulas for each of these thanks i really appreciate it

A. CuCO3 --heat=> CuO + CO2 Cu + 2AgNO3 => Cu(NO3)2 + 2Ag 2Al + 6HCl => 2AlCl3 + 3H2 PbNO3 + NaCO3 => PbCO3 + NaNO3 FeCl3 + 3NaOH => 3NaCl + Fe(OH)3
