nitrogen and oxygen
Carbon, hydrogen, and oxygen.
the elements like sodium,potassium,calcium,sulphates,chlorides,nitrates are present in traces in the tap water...
There are many elements that are contained in seawater. Some examples include magnesium, sulfur, selenium, silicon, fluorine, sodium, and chlorine.
Nitrates and potassium contained in the soil from rotting vegetation and other sources of fertiliser.
the answer is complement
Hydrogen and Oxygen
The book Elements contained axiomic proofs for plane geometry.
Elementally, it reacts most commonly with hydrogen and oxygen. But in the forms of ammonia or nitrates, it will react with most elements.
Hydrogen and carbon.
its false no cap
Mendeleev's first periodic table contained 63 elements. He left gaps for undiscovered elements and predicted their properties based on the patterns of the known elements around them. Mendeleev's table was later expanded to include more elements as they were discovered.
a set of which all the elements are contained in another set.
