What are three examples of a chemical changes?
Three examples of chemical changes include rusting of iron, where iron reacts with oxygen and moisture to form iron oxide; the combustion of wood, which transforms it into ash, carbon dioxide, and water vapor; and the digestion of food, where complex organic molecules are broken down into simpler substances through chemical reactions in the body. These changes result in the formation of new substances, indicating that a chemical reaction has occurred.
What are chemical properties?
Three chemical properties are reactivity, flammability, and oxidation state.
Is a bike rusting in the rain chemical change?
The clouds are the gas form of water. The chemical change is from gas to liquid when it rains.
What is made of two or more substances chemically bonded together?
Many compounds of three or more nonmetals exist. Examples include phosphoric acid and chloroform. Additionally, the very unstable compound carbonic acid is of this type.
What are three things that chemical equations can tell you about a chemical reaction?
A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
What are three categories of controlled substances?
Risk for potential abuse
What carbohydrate family consists of three types of chemical substances?
the chemical substances are carbon, oxygen and hydrogen.
Which class of controlled products is subdivided into three subclasses?
The class of controlled products that is subdivided into three subclasses is the "Controlled Substances" class. This classification typically includes Schedule I, Schedule II, and Schedule III substances, each with varying levels of restriction and potential for abuse. Schedule I substances are considered the most restricted, while Schedule III substances have a lower potential for abuse compared to the others. These subclasses help in regulating the manufacture, distribution, and use of these substances.
What are the three main parts of a chemical equation?
The three main parts of a chemical equation are the reactants, the arrow representing the reaction, and the products. Reactants are the substances that participate in the reaction, while products are the substances formed as a result of the reaction. The arrow indicates the direction of the reaction from reactants to products.

What are three causes of the chemical weathering of rocks?
Three causes of chemical weathering of rocks are exposure to water, exposure to oxygen, and contact with acidic substances such as acid rain. These elements can break down the minerals in rocks by chemical reactions, leading to the weakening and eventual breakdown of the rock material.
What are schedule 5 drugs?
Controlled substances meaning their disturbtion is controlled they are accounted for nurses and doctors must keep accurate track of who got them and when they got them and how many Your three and fours are weaker analgesics and anti anxiety
How to write To separated three substance in past tense?
'separated three substances' is past tense.
What are the three propulsion types?
The three main propulsion types are chemical propulsion, electric propulsion, and nuclear propulsion. Chemical propulsion uses chemical reactions to generate thrust, electric propulsion uses electric power to accelerate propellant to high speeds, and nuclear propulsion uses controlled nuclear reactions for propulsion.
What are three categories of chemical reactions?
The three categories of chemical reactions are synthesis (combination), decomposition, and replacement (single or double displacement) reactions. Synthesis reactions involve the combination of two or more substances to form a new compound. Decomposition reactions involve the breakdown of a compound into simpler substances. Replacement reactions involve the exchange of ions between compounds.
What are chemical properties?
Three chemical properties are reactivity, flammability, and oxidation state.
Who controlled Mexico for over three centuries?
The Spanish Empire controlled Mexico for over three centuries.
