Question

Water, H2O, is made up of different elements, hydrogen and oxygen. Is this type of combination a mixture or a pure substance?
A) Because water is composed of two separate elements, it is a mixture.
B) Because water can be heated and fairly easily turned to steam, it is a mixture.
C) Because water is composed of elements found in the periodic table, it is a pure substance.
D) Because water molecules all have a consistent ratio of hydrogen to oxygen, it is a pure substance.

Answer 1

D) Because water molecules all have a consistent ratio of hydrogen to oxygen,it is pure substance

Answer 2

Here is your answer

D) Because water molecules all have a consistent ratio of hydrogen to oxygen, it is a pure substance.

Water is compound and not mixture. This is on the grounds that mixes are constantly shaped in positive proportion of constituent components. When the hydrogen atoms combine with the oxygen atom, Wouldn't it be considered a mixture, because the atoms were combined to form a new molecule.
