C is wrong, it is a question.
D is wrong, it is an observation,
Answer:
The energy released is 13.53j
Explanation:
Q = Mc∆temp.
Q = energy
M = mass
c = specific heat capacity
∆temp. = change in temperature
Q = 1 x 0.902 x (35 - 20)
Q = 0.902 x 15 = 13.53j

<span>No, xenon will not react on Nitrogen because xenon
only reacts with oxygen and fluorine. Xenon only reacts with the 2 elements
because these 2 elements contain a strong electronegative element which is high
in energy barrier that can move the electrons inside xenon elements. Xenon is an element with a symbol of Xe, it
is odorless and colorless gas. Common uses of xenon are flash lamps and arc
lamps. Xenon is a luminous element, it glows when placed near to high voltage
electric field.

CH3COONa+HBr ----> NaBr + CH3COOH
CH3COO⁻ +H⁺ ------> CH3COOH , because CH3COOH is a weak acid
