The table compares the type of reactants and products taking part in two chemical changes. Chemical Change Comparison
Chemical Reaction Reactants Products
X an element and a compound a compound
Y an element and another element a compound

Which of the following statements correctly identifies the synthesis reaction and explains why?
Only chemical reaction X, because one reactant is a compound
Only chemical reaction Y, because both reactants are elements
Neither chemical reaction X nor Y, because they have only one product
Both chemical reactions X and Y, because there are two reactants and a single product

What happens to the atomic radius when an elctron is lost

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
