We have a test on writing balanced equations for chemical reactionsI am having trouble with it, here are a few example problems, and the instructions at the top, i would appreciate it so much if you would help me.Write complete balanced equations for the list of chemical reactionsTypes of reactions and physical states must be included.Aluminum metal is heated and reacts with Fluorine gasSodium carbonate crystals are heated and decomposedAluminum metal reacts with sulfuric acid and bubbles are producedButane is burnedButane C4H10Solutions of aluminum iodide and silver nitrate are mixedthanks in advance!
.Absolutelyget your sorry ss to the ER and get some help ! .Duh !
all of your thermometers are incorrect.if your temp was 93 degress you wouldnt be asking this question rght now.so go to a doctor and get a non-broken thermometer
Taking your reactions in the order listed: Aluminum reacts with (molecular) fluorine to form aluminum fluoride: 2Al + 3F2 → 2AlF3 (combination or synthesis rection) Sodium carbonate gives off carbon dioxide leaving sodium oxide: Na2CO3 (heat) → Na2O + CO2↑ (decomposition reaction) Aluminum reacts w/ sulfuric acid to form aluminum sulfate hydrogen 2Al + 3H2SO4 → Al2(SO4)3 + 3H2↑ (single replacement) Butane burns w/ oxygen in the air to form carbon dioxide water: 2C4H10 + 13O2 → 8CO2 + 10H2O (combustion) aluminum iodide + silver nitrate form silver iodide + aluminum nitrate: AlI3 + 3AgNO3 → Al(NO3)3 + 3AgI↓ (double replacement) Whew! I hope this answers your question.
