When iron reacts with oxygen, it forms iron oxide, or rust.

4 Fe + 3 O2 2 Fe2O3

If 112 g of iron (Fe) combines with 24 g of oxygen (O2), how much iron oxide is formed?

Which statement describes the appearance of a temperature-vs.-time graph? a horizontal line shows that the temperature increases at a constant rate over time. a vertical line shows that the temperature decreases at a constant rate over time. horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases. horizontal lines where the temperature increases are connected by upward-sloping lines where the temperature is constant for each phase.

Iwill give extra points to who gets this right

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.
