Two atoms total are in NaCl.
Answer:
Explanation:
Aluminium hydroxide () is a base and hydrobromic acid (HBr) is a strong acid.
Hence an acid-base reaction occurs between and HBr
Balanced molecular equation:
Balanced total ionic equation:
Balanced net ionic equation:
(net ionic equation is written by removing common ions present in both side of total ionic equation)
Answer:
A.
Explanation:
The sun unevenly hits the Earth, causing wind to form and move around the poles; never constant.
Here we have to choose the way which is not the common way to judge the quality of the air in a particular area.
The measuring the amount of precipitation in the area is not the common way to determine air quality in an area.
The acidity of the rain causes due to the excess amount of CO₂ and SO₂ in an area. Both the gases cause pollution.
The measuring of the amount of a particular gas element is a renowned way to determine the pollution level of an area.
The ozone is a harmful gas so the measuring of its amount in ground level can identify the level of pollution in the particular area.
