Answer:
chemical change
Explanation:
Ash is formed as result of burning of paper which is a new product. Chemical change a new substance must form.
Identify and name the cation; this is a metal element or polyatomic cation.
Identify and name the anion; this is a nonmetal element. Change the suffix to '-ide,' or use the polyatomic anion name.
Answer: A. the chemical change will occur faster in beaker X.
Explanation:
Temperature is one of the factors that affect the rates of chemical reactions. Increase in temperature increases the rates of reaction by increasing the kinetic energy of the reacting particles so that energetic collisions occur and more bonds in the reactants will be broken and; atoms and ions recombine to form new compounds. Beaker X which is at room temperature has higher temperature than beaker Y which is kept in the refrigerator, thus reacting particles in beaker X has more kinetic energy than the ones in beakerA. the chemical change will occur faster in beaker X. Y.
Answer:
last one is the correct and most suitable option.
Hope it helps!!!
