    Have you tried anything so far?

    4FeS + 11O > 2Fe2O3 + 8SO2
    For the first one?

    Can you tell me if the elements and compounds change in the equation, like do they all stay the same like gas, liquid or solid, or do any of them change?

    Start with the Fe and the S and pay attention to subscripts.

    You start with 1 Fe on the left but have 2 Fe on the right. Do something about this.

    You start with 2 S on the left but have 1 S on the right. Do something about this.

    Initially you need to balance the Fe and the S. After that, account for the O and make necessary balancing adjustments.
