Im doing a quiz but i dont know how to do Single Replacement the way it is is that there should be no charges and both sides need to be balanced, 15 questions someone help with like at least one please imma fail lol. Pb(II) + Zn(C2H3O2)2 --> Fe(II) + Al2O3 --> AlBr3 + Cl2 --> Aluminum metal is combined with aqueous iron (III) bromide Magnesium metal reacts with an aqueous solution of zinc nitrate H2SO4 + Fe(II) --> Li + Fe(NO3)3 --> Au (III) + HCl --> I2 + KBr --> Ni (II) + SnCl2 --> F2 + RbCl --> Fe2O3 + H2 --> Cd + Ag2SO4 --> H2O + Na -->

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
