Solid im pretty sure thats what the (s) means
The electronic configuration of n - 3 ion is [He] 2s2 2p3.
The primary sources of acidity in acid rain are the gases SO and NO So, the correct option is (c) SO and NO
A chemical process that starts when gases like sulphur dioxide and nitrogen oxides are discharged into the atmosphere leads to acid rain. These substances have the ability to ascend very far into the sky, where they combine and react with oxygen, water, and other chemicals to produce acid rain, an additional form of acidic pollution.
Acidic particles corrode metal and hasten the deterioration of paint and stone. Power plants are the primary sources of SO . Burning fossil fuels produces nitrogen dioxide (like gasoline). Cars, lorries, and power plants are the biggest producers of NO.
Therefore, The primary sources of the acidity in acid rain are the gases SO and NO.So, the correct option is (c) SO and NO

Answer:
Explanation:
Q = mcAT= should be mc(T2-T1)
for Aluminum
Q = 3 1000g Al x(0.897J/gC x(23-18 C)= 16722 J
