Answer:
The answer is CH4<CH3OCH3<CH4O<CaCO3
Explanation:
Answer:
a) will react with water: K
b) will react with steam or acid, but not water: Cr & Sn
d) will not react with water, steam, or acid: Cu
Explanation:
K reacts violently with water.
Cr will react with steam to form an oxide + H gas and will react with most acids
Sn will react with steam to form SnO₂ + H gas and, though it does not react as rapidly as other metals in acid, it dissolves easily in concentrated acids
Cu is an extremely nonreactive metal, which is what makes it so suitable for wiring
Answer:
97% of earth's water is in the ocean. The rest could be found underground, in glaciers and ice, and in rivers and lakes

Answer:
H₄SiO₄
Explanation:
From the question given above, the following data were obtained:
Hydrogen (H) = 4 moles
Oxygen (O) = 4 moles
Silicon (Si) = 1 mole
Empirical formula =?
Since the number of mole of each atom of the element present is known, the empirical formula of the compound can be written as follow:
H₄SiO₄
