A chemical reaction causes a chemical change true or false?
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
True or false When sugar is dissolve in water the sugar and water are chemically combined?
False. When sugar is dissolved in water, it is a physical change where the sugar molecules are dispersed in the water but no chemical bonds are formed between them.
Changing water to ice is an example of a chemical change true or false?
I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.
Is this true or false in a chemical change other forms of energy cannot be changed to chemical energy?
False
Is changing the size and shape of pieces of wood a chemical change true or false?
False. Changing the size and shape of pieces of wood is a physical change, not a chemical change. A chemical change involves the alteration of the chemical composition of a substance, while a physical change only affects the physical properties of a substance.
True or false the dissolving of sugar in water is an example of a chemial change?
false - it's a physical change. The sugar remains sugar only in solution.
Is a tree that is cut into boards at a sawmill a chemical change?
Sawing a board in half is not an example of chemical change. It is an example of a physical change. Physical changes on a substance do not change the substance. When you saw a board in half, the two halves of the boards are still boards- they're not anything else.
Is a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
Is changing thesize and shape of pieces of wood a chemical change true or false?
false
Is this true or false in a chemiccal change other forms of energy cannot be changed to chemical energy?
False. In a chemical change, other forms of energy, such as heat or light, can be changed into chemical energy. This transformation can occur during reactions where energy is either absorbed or released as chemical bonds are broken or formed.
True or False When a chemical reaction occurs the physical and chemical properties of the reactants are the same as the properties of the products.?
unnecessary will change physically depending on what type of reaction, sometime chemically change . For example physically change are ice to water (solid to liquid) Chemically change are HCl + NaOH = NaCl + H2O ( the content changed )
Is table salt is an example of an substance true or false?
True because when you mix chloride and sodium you get a chemical change, which in turn creates a new substance.
