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 )

When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Do chemical changes affect the chemical structure of a substance?
yes chemical properties do change a substance physical properties just change the physical shape or look!!!
In chemical reaction how do the chemical properties of the products compare with the chemical properties of the reactants?
the product's properties usually and may differ from the properties of the reactants. Example-salt-sodium, a soft explosive metal and chlorine, a toxic gas. make salt.
What does undergo physical or chemical changes mean?
if during a change the chemical composition of the reactants change or any new products are formed then the reactant is said to undergo chemical change.if the state, color, phase or any other physical properties of the reactant change without any change the chemical composition of the reactants or formation of any new substances then it is said to undergo physical change
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
How do reactants and products and compar before and after a chemical reactgion?
The products have different physical and chemical properties than the reactants.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Why chemical compound does not maintain the same properties as its parent elements?
Because reactants and products have different chemical compositions and consequently different chemical and physical properties.
What happens to the chemical and physical properties of a substance formed in a chemical reaction?
Chemical Properties If it reacts (reactivity) If it corrodes (corrosion) Physical Properties malleable ductile conductivity magnetic
Do chemical changes affect the chemical structure of a substance?
yes chemical properties do change a substance physical properties just change the physical shape or look!!!
How are the terns reactant product and chemical reaction related?
The reactants undergo a chemical reaction and form new products with different physical and chemical properties.
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
Why is mixing hydrochloric acid and sodium a chemical change?
It is a chemical change because the products, H2 and HCl, are completely different from the reactants in their physical and chemical properties.
Can a chemical change make a new product?
All chemical changes make new products that are different from the reactants in their chemical and physical properties.
What are properties in a chemical change?
During a chemical change (chemical reaction) the resulting products have, of course, other properties - compared to the reactants.
What must be true about the properties of the reactants and the properties of the products in a chemical reaction?
The reactants and the products must contain the same numbers of the same types of atoms, that is, atoms with the same atomic number, and either the products must contain at least one type of chemical bond distinct from any chemical bond in the reactants or the reactants must contain at least one type of chemical bond not found in the products.
What does a chemical change always do?
A chemical change always changes the chemical composition of the reactants to produce products with new and unique properties, different from the reactants.
