One way to refine iron from iron ore is to heat the ore with hydrogen gas at high temperatures.
Which change increases the amount of iron produced in the equation
increase temperature
increase pressure
reduce the amount of Fe3O4
add water to the system
1 answer
Increasing temperature would be the change that increases the amount of iron produced in the equation. This is because higher temperatures can increase the rate of the chemical reaction, resulting in a greater yield of iron.
