Concept explainers
(a)
Interpretation:
The explosion of a firecracker is a chemical change or not is to be stated with appropriate evidence.
Concept introduction:
A chemical change takes place when a new substance is produced through a
(b)
Interpretation:
The evaporation of a puddle of water is a chemical change or not is to be stated with appropriate evidence.
Concept introduction:
A chemical change takes place when a new substance is produced through a chemical reaction. The physical change occurs when a matter changes its form but not its chemical identity.
(c)
Interpretation:
The burning of a candle is a chemical change or not is to be stated with appropriate evidence.
Concept introduction:
A chemical change takes place when a new substance is produced through a chemical reaction. The physical change occurs when a matter changes its form but not its chemical identity.
(d)
Interpretation:
The process of dispersion through a prism is a chemical change or not is to be stated with appropriate evidence.
Concept introduction:
A chemical change takes place when a new substance is produced through a chemical reaction. The physical change occurs when a matter changes its form but not its chemical identity.

- hat do the coefficients of a balanced chemical equation tell us about the proportions in which atoms and molecules react on an individual (microscopic) basis?arrow_forwardWrite a chemical equation representing the decomposition of water into two gaseous products. What are the products?arrow_forwardRust Iron and oxygen combine to form iron oxide, orrust. List the reactants and products of this reaction.arrow_forward
- Many over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.arrow_forward(For Exercises 4546) Solutions containing nickel(II) ion are usually bright green in color. When potassium hydroxide is added to such a nickel(II) solution, a pale-green fluffy solid forms and settles out of the solution. The fact that a reaction takes place when potassium hydroxide is added to a solution of nickel(II) ions is an example of a properly. . The fact that a solution of nickel(II) ion is bright green is an example of a property.arrow_forwardThe following demonstration takes place in a two-step process: First, solid calcium carbide (CaC2) reacts with liquid water to produce acetylene gas (C2H2) and aqueous calcium hydroxide. Second, the acetylene gas produced is then ignited with a match, causing the combustion reaction of acetylene with oxygen gas to produce gaseous carbon dioxide and gaseous water. Write the balanced equation for each reaction that is occurring.arrow_forward
- Table 6.1 lists some clues that a chemical reaction has occurred. However, these events do not necessarily prove the existence of a chemical change. Give an example for each of the clues that is not a chemical reaction but a physical change.arrow_forwardFlammability is a measure of how easily a substance bursts into flame, through fire. It is is a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light. O True O Falsearrow_forwardExplain this quote: "Chemical reaction changes the actual chemical itself."arrow_forward
- Substances: 1.Burning of Matches 2. Candle wick in burning of candle 3. Table Salt dissolved in water from the substances above that undergone chemical change, what probable substances it turned to after such change. Explainarrow_forwardIn a chemical reaction, the matter is neither created nor destroyed. True or false? Explain how?arrow_forwardWhat are two examples of hydrated compounds? What is there chemical formula?arrow_forward
