The group number tells us about the size weight and molecule elements involved. Also tells us about what types it can form and combine with as well as its reactions also
Answer:
CO(g) + H2(g) + H2O(g) ==> CO2(g) + 2H2(g)
Explanation:
In the industry, hydrogen is prepared from water and hydrocarbons. Water gas being the major method of preparation of hydrogen industrially.
The water-gas reaction is an industrial process in which steam is passed over red-hot coke giving a gaseous mixture of carbon monoxide and hydrogen:
C + H2O(g) → CO + H2.
The mixture of CO and H2 is Futher passed through steam according to the equation:
CO(g) + H2(g) + H2O(g) ==> CO2(g) + 2H2(g) to give hydrogen and carbon dioxide.
Answer:
12: This is decomposition because nitrogen triiodide is breaking apart.
13: This is double displacement because the elements in the compounds are "switching".
14: This is synthesis because the water and carbon dioxide are combining.
15: This is also synthesis because the hydrogen and oxygen are combining.
16: This is single displacement because the sodium is "switching" the element it's bonding with.
