How do I write chemical formulas between each of the pairs of elements then name the compound?
Q. A compound between Aluminum and Hydroxide: A compound between Magnesium and Nitrate: A compound between Fluorine and Calcium: A compound between Sulfur and Magnesium: A compound between Chrlorine and Lithium: I would really appreciate some help with explaining how to do it. Does anyone know the steps you would take to get the answer?

A. Al3+ + 3OH- ---> Al(OH)3 Mg2+ + 2NO3- ---> Mg(NO3)2 2F- + Ca2+ ---> CaF2 Mg2+ + SO42- ---> MgSO4 (sulfate not sulfur) Cl- + Li+ ---> LiCl you just need to look at the respective charges on the atoms/compounds. for example fluorine has one negative charge, but calcium has two positive charges, so you need two fluorine atoms for every calcium atom to balance the charges.

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. I need to balance they chemical equations; 1. Sodium + Water --> Hydrogen Gas + Sodium Hydroxide 2Na + 2HOH --> H2 + 2NaOH 2. Sodium Chloride + Sulfuric Acid --> Hydrogen Chloride + Sodium Sulfate 2NaCl + H2SO4 --> 2HCl + NaSO4 3. Aluminum + Iron (III) Oxide… [cont.]

Q. Use the following order of steps to get a correctly written equation. You do not need to write the steps out separately. 1) Write the correct formulas for the reactants. 2) Classify the type of reaction as synthesis (S), decomposition (D), single replacement (SR), double replacement (DR), or combustion (C). 3) Predict and write the correct formulas for the products. 4) Include the physical state of each substance. 5) Balance the equation. a. Solutions of aluminum sulfate and sodium phosphate are mixed. b. Solutions of magnesium chloride and silver nitrate are mixed. c. Kerosene (C12H26) is burned. d. Hydrogen gas reacts with oxygen gas to make water. e. Cellulose (wood, C6H10O5) is burned. f. Sulfur trioxide gas reacts with water to form… [cont.]
