Answer:
the correct answer is option C. Na
Answer:
518.52K
Explanation:
Charles law, which describes the direct relationship between the volume and the temperature of a gas when the pressure is constant, will be used for this question. The Charles law equation is:
V1/T1 = V2/T2
Where; V1 is the volume of the gas at an initial state (Litres)
T1 is the absolute temperature of the gas at an initial state (Kelvin)
V2 is the volume of the gas at a final state (Litres)
T2 is the absolute temperature of the gas at a final state (Kelvin)
According to the question, V1 = 2.3L, T1 = 25°C, V2 = 4L, T2 = ?
We need to convert the temperature to the absolute temperature unit in Kelvin (K) i.e.
T(K) = T(°C) + 273.15
T(K) = 25°C + 273.15
T1 (K) = 298.15K
To find for T2 in the equation, we make T2 the subject of the formula:
T2 = V2 × T1 / V1
T2 = 4 × 298.15 / 2.3
T2 = 1192.6/2.3
T2 = 518.52
Thus, the temperature must be heated to 518.52K in order to expand to a volume of 4L. This answer is in accordance to Charles law that the volume increases with increase in temperature and vice versa.

Explanation:
Isotopes are chemical species of the same elements with different number of neutrons but the same protons.
Both Chlorine-35 and Chlorine-36 are the same because they are both isotopes of the same elements that is Chlorine. Also, both Chlorine-35 and Chlorine-36 have the same number of protons which has the value equal to 17.
The difference between Chlorine-35 and Chlorine-36 is that Chlorine-35 is stable and has the abundance of 75.77% whole Chlorine-36 is found in trace.
Also Chlorine-35 has a neutrons value of 18 while that of Chlorine-36 is 19.
