1. First step: a physical change 2. Second step: a chemical change
Is mixing milk and cream to a physical or a chemical change?
It would be a chemical change, because if it was a physical change it would stay the same substance, but in a chemical change you mix 2 different substances to get a new substance.
Is mixing 2 chemicals a white powder forming chemical change?
Any chemical reactions - a physical phenomenon. To discuss a chemical change please mention the two chemicals.
What are three ways to name a chemical?
Chemical name (e.g. ethanol), common name (e.g. rubbing alcohol), and IUPAC name (e.g. 2-propanol) are three ways to name a chemical compound.
What makes up a chemical change?
A chemical change involves the formation of new substances with different chemical properties than the original ones. This can involve the breaking and forming of chemical bonds, resulting in a change in the composition and structure of molecules. Evidence of a chemical change includes the release or absorption of energy, color change, formation of a precipitate, or production of gas.
What are 2 ways that matter can change?
Matter can change through physical changes, such as melting or boiling, which alter its form but not its chemical composition. Matter can also undergo chemical changes, where its chemical composition is altered through chemical reactions like rusting or burning.
What are Ways to change the rate of a chemical reaction?
1. Increase the temp 2. Increase surface area 3. Increase the pressure of the system
What has to happen for a chemical change to happen?
At least 2 of the reactants must change their chemical formula.
Is formation of water when hydrogen burns a chemical change or a chemical property?
The formation of water when hydrogen burns is a chemical change. It involves the rearrangement of atoms to form a new substance, water, with different chemical properties than the original hydrogen gas.
What are 4 ways in which you can manage air and water resources more wisely?
Four ways in which you can manage air and water resources more wisely 1.Prevent and reduce waste and pollution 2.Prevent and reduce potentially harmful chemical exposures to employees and members 3.Reduce risks of accidents and releases 4.Prevent or reduce potential liabilities and regulatory compliance burdens.
Is Digesting an apple a physical or chemical change?
1. First step: a physical change 2. Second step: a chemical change
How would you determine if a chemical change has occurred?
You can determine if a chemical change has occurred by looking for signs such as a change in color, formation of a precipitate, evolution of gas, or release of heat or light. Additionally, if the chemical composition of the substance has been altered, it is likely that a chemical change has taken place.
What are three indicators of a chemical reaction occurring?
there are mainly two ways that indicate that a chemical change has taken place. These ways are the physical properties (the way things look, without changing the chemical makeup of a substance) are different, and the chemical properties (the way the substance reacts with other substances) are different.
Give four ways you can prevent other student from reading work you have saved on a laptop?
You can lock it 1 you can help them 2 change the password3 take the computer away 4
What are the ways rates of chemical change can be changed?
Rate of chemical change can be altered by 1. Changing the temperature. 2. Changing the pressure (if gases are involved). 3. Changing the particle size of a solid reactant. 4. Changing the concentration of a dissolved reactant. 5. Adding a suitable catalyst.
What r the 2 differentces of a physical and chemical change?
A chemical change involve the molecular modification of reactants.After a physical change the molecule remain unchanged.
How do you illustrate chemical change versus physical change in a venn diagram?
by drawing 2 circles and compare and contrast chemical and physical change
