2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(s) H = -850 J 1. How much energy would be released if 5.2 moles of aluminum reacted with excess iron (III) oxide?

2. If you started this reaction with 4.9g of aluminum, how much energy would be produced?

Calculate - analysis of compound composed of iron and oxygen yields 174.86 of fe and 75.14g of o. what is the empirical formula for this compound?

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
