1- When a quantity of blue copper hydroxide is heated, it decomposes into
الإجابة: b- Copper oxide and water vapor.

2- The number of collisions between molecules increases, thereby increasing the speed of the chemical reaction as a result of
الإجابة: d- A and C together.

3- When a pure long-stemmed red-flowered pea plant is pollinated with a short-stemmed white-flowered pea plant, the first generation will consist entirely of plants that are
الإجابة: a- Tall plants with red flowers

State the importance of each of the following:

4- The oxidase enzyme found in potatoes.
الإجابة: It acts as a catalyst that increases the speed of decomposition of hydrogen peroxide into water and oxygen gas.

5- Chemical reactions.
الإجابة: They are essential in many industries like medicines, fertilizers, and plastics, as well as for photosynthesis in plants and burning fuel in car engines.

6- The sliding rheostat.
الإجابة: To control the electric current intensity passing through the electric circuit, and consequently control the potential difference.

Study the following two figures and answer the questions below each one:

Figure 7:
a- The type of the reaction is:
الإجابة: Double substitution reaction (Acid with salt).

b- The gas evolved is:
الإجابة: Carbon dioxide gas (CO2).

Figure 8: From the electric circuit
a- The ammeter is connected in:
الإجابة: series

b- The reading of the voltmeter =:
الإجابة: 6 Volts (V = I x R = 2 x 3 = 6 V).

Question 2: Place a check mark (✓) or (✗) in front of the appropriate answer for each of the following statements:

9- Ohm = coulomb × volt.
الإجابة: (✗)

10- Alpha, beta, and gamma radiation is considered visible radiation.
الإجابة: (✗)

11- The pancreas secretes the insulin hormone to decrease the blood sugar levels.
الإجابة: (✓)

What happens when...?

12- Increasing the surface area of reacting materials related to the speed of the chemical reaction.
الإجابة: The speed of the chemical reaction increases.

13- Increasing the number of neutrons over the number of protons in the nuclei of some elements than the number necessary for their stability.
الإجابة: The element becomes unstable and radioactive, and it emits nuclear radiations to reach stability.

14- Connecting the voltmeter between the two poles of an electrical source in an open electrical circuit.
الإجابة: It measures the electromotive force (e.m.f.) of the electrical source.

15- How do we measure the speed of a chemical reaction practically?
الإجابة: By the rate of disappearance of one of the reactants, or the rate of appearance of one of the products.

16- Illustrate how to connect three electric columns, the e.m.f each of them is 2 volts, to obtain a battery with e.m.f equale 4 volts.
الإجابة: By connecting two electric columns in parallel (their total e.m.f = 2 volts), and then connecting them in series with the third electric column (2 volts), so the total e.m.f of the battery becomes: 2 + 2 = 4 volts.

Question 3: Write what the following expressions mean:

17- Arrange the metallic elements in descending order according to their chemical activity.
الإجابة: Chemical activity series

18- The intensity of the electric current passing through a conductor is directly proportional to the potential difference between its two ends when the temperature is constant.
الإجابة: Ohm's Law

19- The cells which the hormones affect and they are located away from the endocrine gland that secretes hormone.
الإجابة: Target cells
