1Write the formula Aaluminum hydrogen sulfate2or each of the following ions, indicate the total number of protons and electrons in the ionFor positive ions in the list, predict the formula of the simplest compound formed between each positive ion and the oxide ionFor the negative ions in the list, predict the formula of the simplest compound formed between each negative ion and the aluminum ion.A S2- number of protons 16 and number of electrons 18How do i put this in a formula?3By analogy with phosphorus compounds, name the following: AMgHSbO4 BMg3(SbO4)2 CNa2HAsO4Im confused about this one

Answer:

My friend just bought one, its the Brand New model for this yearHis has a Full metal gearbox which is great! I do know from people though that earlier models didnt have the metal gearbox's and didnt have long life spans bc of thatGo to a local airsoft store and have a tech tell you if you don't know how to take it apart yourself.
1.) hydrogen sulfate HSO4- Aluminum has an oxidation state of 3, so it's Al 3+ That gives you Al(HSO4)3 2a.) You're correct on the of protons and electronsFor the formula with Aluminum, you have Al 3+ and S 2-You need to balance out the charges, so 2Al is 6+, and 3S is 6-That gives yo a formula of Al2S3 3.) The key here is to take the analogy from PO4 (phosphate), and use it to figure out the name of the xO4 ionsA.) PO4 is phosphate, so SbO4 is AntimonateMagnesium Hydrogen AntimonateCAsO4 would be ArsenateSodium Hydrogen Arsenate.
