First choice: PhH4 has a lower boiling point
Second: SiF4 higher
Third: CBr4 higher
There is no picture hunny. Please add a picture please boo.
The H+ concentration in the lake has increased as a result of the acid rain.
The original pH of the lake was 7, which mean the water is neutral, but due to the acid rain, it drops to 5. This means, that the water has become acidic and how have more hydrogen ion. The H+ concentration in the lake has 100 times compares with its original pH.
Neon I think. Go to the periodic table and see which one is the 11th
