General Chemistry Chapter 7
Calculate the theoretical yield in grams of AlI3 from the complete of 18.3 grams of Al according to the following balanced equation: 2 Al (s) + 3 I2 (s) -> 2 AlI3 (s)
18.3 grarams Al2 x (1 mol of Al/26.98 g of Al) x (2 mol of AlI3/2 mol of Al) x (407.7 g AlI3/1 mol AlI3) = 227 g AlI3
What numbers belong in the blank spaces to fully balance the following reaction? __Fe (s) + __Cl₂ (g) → __FeCl₃ (s)
2 , 3 , 2 Matter is conserved in a chemical reaction. Balanced equations contain the same number of atoms of each element on each side of the equation. A coefficient of 2 in front of Fe, a coefficient of 3 in front of Cl₂, and a coefficient of 2 in front of FeCl₃ yield the same number of Fe and Cl atoms on both sides of the equation.
How many oxygen atoms are located on the reactant side of the following chemical equation? 2 Al(s) + Fe₂O₃(s) → Al₂O₃(s) + 2 Fe(l)
3 2 Al(s) + Fe₂O₃(s) → Al₂O₃(s) + 2 Fe(l) Oxygen can be found in iron(III) oxide, Fe₂O₃. Every molecule of Fe₂O₃ contains 2 Fe atoms and 3 oxygen atoms.
Write the balanced molecular chemical equation for the reaction in aqueous solution for strontium hydroxide and manganese(V) iodide. If no reaction occurs, write NR
5 Sr(OH)₂(aq) + 2 MnI₅(aq) → 2 Mn(OH)₅(s) + 5 SrI₂(aq)
When butanol (C₄H₉OH) is burned in oxygen, CO₂ and H₂O are the products. What is the coefficient in front of the O₂ in the balanced equation (using only whole numbers and the lowest whole number ratio)?
6 Matter is conserved in a chemical reaction. Balanced equations contain the same number of atoms of each element on each side of the equation. The balanced equation for this reaction is: C₄H₉OH + 6 O₂ → 4 CO₂ + 5 H₂O.
Balance the following chemical reaction: Al₂(SO₄)₃ (aq) + K₃PO₄ (aq) → AlPO₄ (s) + K₂SO₄ (aq)
Al₂(SO₄)₃ (aq) + 2 K₃PO₄ (aq) → 2 AlPO₄ (s) + 3 K₂SO₄ (aq)
spectator ions
Ions that do not take part in a chemical reaction and are found in solution both before and after the reaction "its a spectator sport" being present but not participating in the action
An aqueous solution of Mg(NO₃)₂ and NaOH generates the solid precipitate Mg(OH)₂. Which of the following would NOT appear in the corresponding net ionic reaction?
NO₃⁻ Nitrate does not appear in the net ionic reaction because it is a spectator ion.
Consider the following reaction: C₆H₁₄ + 19/2O₂ → 7H₂O + 6CO₂. Here, C₆H₁₄ is a(n):
Reactant & Hydrocarbon C₆H₁₄ is a reactant in this reaction and is also a hydrocarbon.
