What's your trouble here. You need to learn to do this yourself. I'll be glad to help you through.
first write just the compounds.
K2CO3 + MgCl = KCl + MgCO3
Note you have 2K on the left, but just one on the right. Fix that:
K2CO3 + MgCl2 = 2KCl + MgCO3
Now things match on both sides
Similarly, you can work your way to
H2SO4 + CaCO3 = CaSO4 + CO2 + H2O
Na2SO4 + Ca(NO3)2 = CaSO4 + 2NaNO3
SF4 + 3H2O = H2SO3 + 4HF
Redox Titrations: a. write 2-3 sentences describing and identifying the type of chemical reaction that occurs when Fe2+ reacts with potassium permanganate (KMnO4) and specifying the type of solution for the reaction to occur. b. using a standard reduction
Consider the reaction of solid aluminum iodide and potassium metal to form solid potassium iodide and aluminum metal. The balanced chemical equation is AlI₃(s) + 3 K(s) → 3 KI(s) + Al(s). Given the reaction has a percent yield of 67.8%, what is the
Insoluble silver carbonate, Ag2CO3(s), forms in the following balanced chemical reaction: 2AgNO3(aq) + K2CO3(aq) = Ag2CO3(s) + 2KNO3(aq). What mass of silver nitrate, 2AgNO3(aq), reacts with 25.0 g of potassium carbonate,K2CO3(aq),if there is at least 5.5
Potassium, a silvery metal, reacts with bromine, a corrosive, reddish liquid, to yield potassium bromide, a white solid. Write the balanced equation, and identify the oxidizing and reducing agents.
