The list of answers were not provided. Hydrogen cyanide is the only one on that list that is not commonly produced by double replacement reactions and away.
Hydrogen cynanide
A precipitate, water, or a gas must be produced for a double displacement reaction to occur.
67.2
It is produced by reacting nitrogen gas with hydrogen gas.
Hydrogen gas is produced.
Hydrogen is produced at the anode at twice the rate of oxygen produced at the cathode, because of the ratio of hydrogen to oxygen that makes up water: 2 : 1.
precipitate :)
it depends on what is reacting most commonly it is H2 gas or O2 gas or CO2 gas
NH4OH(aq) + HNO3(aq) --> NH4NO3(aq) + H2O(l) Aqueous ammonium nitrate and water are products.
A precipitate, water, or a gas must be produced for a double displacement reaction to occur.
carbon dioxide, fluorocarbons
A precipitate, water, or a gas must be produced for a double displacement reaction to occur.
For a double replacement reaction to take place, one of following must occur:One product is only slightly soluble and precipitates from solutionOne product is a gas that bubbles out of the mixtureOne product is a molecular compound
double-displacement

The gas that is typically produced when a metal reacts with an acid is hydrogen. However, other gases could be released depending on which metal and acid is used.
Chlorine gas is produced.
It is produced by reacting nitrogen gas with hydrogen gas.
