Enter your ansTwer in the provided box. One of the reactions that occurs in a blast furnace, in which iron ore is converted to cast iron, is Fe 03+3C0→ 2Fe + 3CO2 Suppose that 1.49 x 10 kg of Fe is obtained from a 2.38 x 10 kg sample of Fe,O3. Assuming that the reaction goes to completion, what is the percent purity of Fe203 in the original sample? % purity

7. Complete and balance the equations for the reactions. All reactions yield products. Cl2(g) (a) Mg(s) (b) H2O2() A H20(I) (c) Cul(aq) 8. For each of the following reactions, predict the products, converting each to a balanced formula equation. (a) Aqueous solutions of phosphoric acid and potassium hydroxide are mixed together.

Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of K2S and Fe(NO3)2 are mixed.

Complete and balance the molecular equation for the reaction of aqueous iron (III) nitrate, Fe(NO3)3, and aqueous lithium hydroxide, LiOH. Include physical states. Screenshot below. The first one is an issue I have.

A three-step process for producing molten iron metal from Fe203 is: 1. ЗFe203 + со — 2Fe3О4 + CO2 2. Fe304 + CO— ЗFeО + CO2 3. Feo + CO → Fe + CO2 Assuming that the reactant CO is present in excess and that the yields, respectively, for the three steps are 81.9%, 65.9% and 60.5%, what mass of iron metal would be produced from 360. kg of Fe,03?

A fictitious metal called Oscium (MM = 72.4 g· mol) reacts with nitrogen gas according to the following reaction: 6 Oc (s) + N2(g) + 2 OC3N(s)

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. [] + KClO(aq) + H,O(1) · X Ś

4. Imagine that you are given 0.2500 g of a sample of copper(II) sulfate pentahydrate (CuSO4 • 5 H2O). You very carefully heat the compound for an extended period of time to drive off water, after which you determine the mass of the remaining solid to be 0.1598 g. (i) Determine whether the data given confirm the formula of the hydrate. You must (ii) show any relevant calculations that support your answer.
