A chemist wants to extract copper metal from copper chloride solution. The chemist places 1.50 grams of aluminum foil in a solution of 14 grams of copper (II) chloride. A single replacement reaction takes place. What best explains the state of the reaction mixture after the reaction? Unbalanced equation: CuCl2 + Al → AlCl3 + Cu

I need help with questions 3 and 4?

A common demonstration in chemistry courses involves adding a tiny speck of magnesium(IV) oxide to a concentrated hydrogen peroxide H2O2 solution Hydrogen peroxide is unstable and it decomposes quite spectacularly under these conditions to produce get oxygen gas and steam magnesium (IV) oxide is a catalyst for the decomposition of hydrogen peroxide and is not consumed in the reaction she was the balance equation for the decomposition reaction of hydrogen peroxide

Could someone please Help! No plagiarism Please! 1. Consider the following reaction:  2H₂O (l)    →    2H₂ (g)    +     O₂ (g)                                   Which of the following statements is/are true for this reaction?                     A. This is a synthesis reaction. B. This is a decomposition reaction. C. This is a combustion reaction. D.None of the above   2. The reaction below shows the equation for the combustion of methane gas. How does the chemical equation demonstrate the Law of Conservation of Matter?   A. There is one CH₄ molecule on the reactant side and one CO₂ molecule on the product side of the reaction. B. There are two O₂ molecules on the reactant side and two H₂O molecules on the product side in the reaction. C. There are four oxygen atoms, four hydrogen atoms and one carbon atom on both the reactant and product side of the reaction. D. The reaction does not satisfy the Law of Conservation of Matter.   3. Chemists use the activity…

Classify each equation as either decomposition, combination, or combustion.

For each of the reactions, calculate the mass (in grams) of the product formed when 15.67 g of the underlined reactant completely reacts. Assume that there is more than enough of the other reactant. 2K(s)+Cl2(g)−−−−−→2KCl(s) 2K(s)+Br2(l)−−−−−→2KBr(s) 4Cr(s)+3O2(g)−−−−−→2Cr2O3(s) 2Sr(s)−−−−+O2(g)→2SrO(s)

3. Complete the following neutralization reactions. Word equations should be completed as word equations, and chemical equations should be completed as balanced chemical reactions. a. sulphuric acid + lithium hydroxide → b. KOH + H₂SO4 12 4. For one of the fuels in gasoline, pentane (CH2), complete the following combustion reactions. Make certain your equations are balanced. a. complete combustion C+0₁ H₂→ 5 12 2 b. incomplete combustion C+012 + H₂

BALANCING EQUATIONS Balance the following chemical equations and determine the type of chemical reaction (i.e. combination reaction, decomposition reaction, single-displacement reaction, double-displacement reaction, or combus- tion reaction). 12) B,0,(s) + HF(1) → BF,(g) + H,0(1)

Write the word equation below and determine the type of reaction (synthesis/combination,decomposition,single-displacement,double-displacement or combustion. 2H20=2H2+02
