Calculate the number of moles of NH3 that result when 5.56 mol of H2 combines with 2.35mol of N2.

Could I have help with these two questions homework questions im not really understanding this unit

Use the solubility generalizations on the information page to predict if one or more precipitates will form when aqueous solutions of sodium hydroxide (NaOH) and iron(II) chloride (FeCl₂) are mixed. Write the formula of any precipitate that could form in one of the boxes. If a box is not needed, leave it blank. If no precipitate is predicted, leave both boxes blank.

4. Consider the reaction MnO2 + 4HCI→ MnCl2 + Cl2 + H2O If 86.3 L of MnO2 and 48.2L of HCl react, a) Which reagent will be used up first? Which is the limiting reagent? b) How many grams of Cla will be produced?

Chemistry part c is incorrect the answer is not 0.

Please don't provide handwriting solution

I very confused mid way in the equation when trying to do conversions.

What type of chemical reaction

Chemistry A chemical reaction with an unknown substance (M) is given below: M(s)+2HCl(aq) →MCL2(aq)+H2(g) if the mass of the unknown substance is 0.0290g, find the amount of moles.

Complete the table below by deciding whether a precipitate forms when aqueous solutions A and B are mixed. If a precipitate will form, enter its empirical formula in the last column. solution A barium bromide potassium sulfide potassium hydroxide solution B potassium acetate zinc sulfate magnesium nitrate Does a precipitate form when A and B are mixed? yes yes yes no no no empirical formula of precipitate 0 0 0 × Ś
