What are 5 key words in a chemical change?
Reactants: Substances that are present before a chemical reaction occurs. Products: Substances that are produced as a result of a chemical reaction. Chemical reaction: Process where reactants are transformed into products, often involving the breaking and forming of chemical bonds. Energy: May be absorbed or released during chemical reactions, impacting the reaction's outcome. Catalyst: Substance that speeds up a chemical reaction without being consumed in the process.
What is the purpose of a chemical equation?
I don't remember all of the mathematical names, but I do remember that you need to balance equations so that both sides will be equal. These are very simple examples but they will show you that balanced equations are equivalentto being equal.Such as: (2+2)=4=(3+1) Both sides equal '4'.Differing equations on opposite sides of the equal sign demonstrate that are differing ways to express a certain figure.Or: (2+6)-(3x1)=5=(2x2)+(4-3) Here both sides equal '5'.(8) - (3) =5= (4) + (1)Hope this helps.
What is the chemical reaction of potassium hydroxide with iodine?
When potassium hydroxide reacts with iodine, it forms potassium iodide and potassium iodate. The balanced chemical equation for this reaction is 6 KOH + 3 I2 → 5 KI + KIO3 + 3 H2O.
What is the chemical reaction Propane burns in oxygen to produce carbon dioxide and steam.?
Study island answer: C3H8 + 5O2 3CO2 + 4H2O
What are the characteristics of a chemical reaction with example?
A chemical reaction involves the breaking and formation of chemical bonds between atoms to create new substances. Some characteristics include the reorganization of atoms, the release or absorption of energy, and the formation of new chemical properties. For example, when hydrogen gas reacts with oxygen gas to form water, new chemical bonds are formed and energy is released in the form of heat and light.

What is the chemical reaction for this equation C3H8 plus 5 O2 3 CO2 plus 4 H20 plus energy?
This is the chemical reaction for burning of propane.
One of 5 things have to happen for a chemical reaction to take place?
the requiredactivation energy is the basic factor for a reaction to start.
What is the chemical equation for the burning of propane if all the products and reactants are in the gas phase?
The chemical reaction is:C3H8 + 5 O2 = # CO2 + 4 H2O
What is the word equation for propane when burning?
The chemical reaction is: C3H8 + 5 O2 = 3 CO2 + 4 H2O

What are the 5 important factors that influence the rate of a chemical reaction?
The key factors that influence the rate of a chemical reaction are concentration of reactants, temperature, presence of a catalyst, surface area of reactants, and the nature of the reactants and products.
What are the 5 signs of a chemical changing?
Five signs of Chemical changes are... 1. light is emitted 2. sound 3. new smell 4. bubbles 5. changes in density There are more than five signs, but theses are the ones I can think of right now.
