Physical change copper chloride aluminum foil experiment?
When aluminum foil is added to copper chloride solution, a chemical reaction occurs where the aluminum replaces the copper in the compound to form aluminum chloride and copper metal. This is a chemical change because the composition of the substances is altered. The physical change that occurs is the color change of the solution from blue to greenish-brown due to the formation of copper metal.
What happens to ferric oxide solution when aluminum chloride is added?
When aluminum chloride is added to a ferric oxide solution, a chemical reaction occurs where the aluminum displaces the iron in the ferric oxide, forming aluminum oxide and iron chloride. This results in a color change and the formation of a precipitate of aluminum hydroxide.
What is the balanced equation of hydrobromic acid added to tin metal?
hydrobromic acid + tin -> tin bromide + hydrogen 2HBr (aq) + Sn (s) -> SnBr2 (s) + H2 (g)
What is the chemical reaction when you mix aluminum and copper sulfate?
When aluminum is added to copper sulfate, a displacement reaction occurs where aluminum displaces copper from the compound. This results in the formation of aluminum sulfate and copper metal. The reaction is exothermic and releases heat.
What is the reaction when aluminum is added to copper sulfate?
When aluminum is added to copper sulfate, a single displacement reaction occurs where the aluminum replaces the copper in the compound to form aluminum sulfate and copper metal. This reaction is represented by the equation: 2Al(s) + 3CuSO4(aq) -> Al2(SO4)3(aq) + 3Cu(s).

What is the balanced equation for ammonium hydroxide added to hydrobromic acid?
The equation is NH4OH + HBr -> NH4Br + H2O.
What is the balanced equation of hydrobromic acid added to tin metal?
hydrobromic acid + tin -> tin bromide + hydrogen 2HBr (aq) + Sn (s) -> SnBr2 (s) + H2 (g)
Milk curdles when lemon juice is added to it. The change that occurs in the protein is called?
It is called denaturation
What occurs when liquids change to gases as heat is added?
evaporation
Which change of state occurs when heat is added to a liquid?
gas!

If phenolphthalein is added to HBr?
If phenolphthalein is added to HBr (hydrobromic acid), which is a strong acid, the phenolphthalein indicator will remain colorless because it only changes color in the presence of a base. Since HBr is an acid, it will not cause the indicator to change color.
What happens if aluminum is added in dilute hcl?
When aluminum is added to dilute hydrochloric acid (HCl), a chemical reaction occurs. The aluminum reacts with the HCl to form aluminum chloride and hydrogen gas. The reaction is exothermic and produces bubbles of hydrogen gas as it proceeds.
The change in an objects volume that occurs when heat is added is called?
thermal expansion
