Other than that, just write out the ions with their charges then switch the ion charges up. For example: Sodium Sulfide Na + + S 2- The two negative charge on the sulfur goes down to the sodium to get Na2. Then the one positive charge on the sodium goes down on the sulfur to get S. So the formula for sodium sulfide is Na2S. I really hoped this helped.

A. OK obviously balancing equations means making them the same on the left and right. To do this you'll need general knowledge of two things: First, you'll need general knowledge of oxidation points, or a table, and second, you'll need knowledge of polyatomic ions. 1) The way to solve this is to know that the formula for Ammonia is NH3. Only way. Then you can figure out that to make that, you need one N and three H's. But H's cannot come in threes. And N's cannot come alone. They have to come in multiples of 2, as they are HOFBrINCl molecules. So the answer would be N2 + H6 --> 2 NH3. Type of reaction- synthesis. 2) To solve this you must know that Chlorate is ClO3-. So 2 KClO3--> 2 KCl + O2, cause Oxygens are also hofbrincl's. Type of… [cont.]

Calcium Hydroxide + Magnesium Bicarbonate --> Magnesium Hydroxide + Calcium Bicarbonate Ca(OH)2 + Mg(HCO3)2 --> Mg(OH)2 + Ca(HCO3)2 5. Potassium + Aluminum Chloride --> Aluminum + Potassium Chloride 3K + AlCl3 --> Al + 3KCl 6. Copper + Silver Sulfate --> Silver + Copper Sulfate Cu + Ag2SO4 --> 2Ag + CuSO4 7. Sulfuric Acid + Calcium Phosphate --> ??? + ??? 3H2SO4 + Ca3(PO4)2 --> 2H3PO4 & 3CaSO4 8. Chlorine + Magnesium Bromide --> Magnesium chloride & Bromine Cl2 + MgBr2 --> MgCl2 + Br2 9.

Q. Single replacement and double replacement reactions; Instructions: 1. Follow the previous instructions regarding identification of the reaction types, writing correct chemical formulas and balancing the equations. 2. Complex ions are assumed to remain intact and are balanced as complete units. 3. It is convenient to write water as HOH for single and double replacement reactions. please help me with the following questions below, I tried to answer them, some I got some I didn't.

A. the acids are probably ionic because they donate H+ ions.

A. Good job on tackling a tough assignment! You may want to double check #2. Phosphorpus can exist as a polyatomic (like sulfur). P4. Likely, the answer you provided is acceptable to your teacher. Also, remember that ionic compounds are composed of a metal and a nonmetal OR a cation and an ion (see #3). Examine your formula for glucose (#6), its composed of all nonmetals. Therefore glucose cannot be an element. Hydrofluoric acid (#9), the "hydro" in the name tells you that there is NO oxygen in the formula. HF Hope that helps
