What is the chemical property of a metal statue?
Density is one property that is the same for the water in both beakers, even though volume is different. The ability to tarnish is an example of a chemical property of a metal statue.
What statement describes a chemical property of an object?
A chemical property can be observed without changing the identity of the substance. A physical property is a characteristic that can be observed without changing the substance into another substance. The object reacts with acid to form water.
Which statement describes a chemical property of aluminum?
(1) Aluminum is malleable. (2) Aluminum reacts with sulfuric acid. (3) Aluminum conducts an electric current. (4) Aluminum has a density of 2.698 g/cm3 at STP….Which statement describes a chemical property of aluminum?
| Atomic number | 13 |

Which is a physical property of aluminum *?
Physical properties It has a melting point of 660°C (1,220°F) and a boiling point of 2,327-2,450°C (4,221-4,442°F). The density is 2.708 grams per cubic centimeter. Aluminum is both ductile and malleable. Ductile means capable of being pulled into thin wires.
Which statement best describes a chemical property of oxygen?
The changes occurs in composition and identity of a substance. Oxygen can combine with a metal to produce a compound is a chemical property while rest of the options are shows physical properties. Therefore, the correct answer is (2).
Which substance can be broken down by chemical means?
Gold, silver, and oxygen are examples of elements. Compounds are pure substances formed by the combination of elements; they can be decomposed by ordinary chemical means. Baking soda is a compound; it contains the elements sodium, hydrogen, carbon, and oxygen, and it decomposes on heating.
Is mixing magnesium with HCl a chemical change?
You know that a chemical change has occurred when the chemical composition of the material changes and a new substance is produced. For the element magnesium (Mg), we could say that chemical properties include: the reaction with oxygen to form MgO. the reaction with hydrochloric acid to form MgCl2 and hydrogen gas (H2)
What happens when magnesium is mixed with hydrochloric acid?
Adding magnesium metal to hydrochloric acid produces hydrogen gas. The magnesium dissolves to form magnesium chloride, MgCl2.
Is magnesium in hydrochloric acid a chemical reaction?
Magnesium reacts with hydrochloric acid according to the equation: Mg(s) + 2 HCl(aq) –> MgCl 2(aq) + H 2(g) This demonstration can be used to illustrate the characteristic reaction of metals with acid, a single replacement reaction, or to demonstrate the generation of hydrogen gas.
What is the product of Zn HCl?
The metal zinc readily reacts with hydrochloric acid to produce hydrogen gas (H2) and zinc chloride (ZnCl2).
What type of reaction is Mg HCl → MgCl2 H2?
redox reaction
What happens when Aluminium reacts with hydrochloric acid?
The metal aluminium dissolves in hydrochloric acid, producing aluminum chloride and colorless hydrogen gas. The reaction taking place between aluminium and hydrochloric acid is irreversible. And the final products will not react with each other.
What are the two products of the reaction between an acid and a base?
When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
What is produced when acid is added to base?
The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. For example, the reaction of hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules.
