Write a balanced equation for the following by inserting the correct coefficients (if a coefficient = 1, enter "1" in the provided box). H20(g) + Fe(s) → H2(g) + Fe3O4(s)

If 200 kJ of heat are supplied, how many grams of NO can be produced? N2(g) + O2(g)→ 2 NO(g) AH = 180.6 kJ/mol O 66.5 g 54.2 g O 30.1 g O 2.21 g

When heated, metal hydroxides decompose to produce a metal oxide and water. Selected the correct balanced equation for the decomposition of calcium hydroxide.     CaOH (s) → CaO2 (s) + H2O (g)     Ca(OH)2 (s) → CaO (s) + H2O (g)     2 CaOH (s) → 2 CaO (s) + H2O (g)     3 Ca(OH)2 (s) → 3 CaO2 (s) + H2O (g)

Predict the products of the following reaction. If no reaction will occur, use the NO REACTION button. Be sure your chemical equation is balanced! K,s (s) + HNO,(ag) → 0

Balance the following chemical equation (if necessary): C₃H₆(g)+O₂(g)→CO₂(g)+H₂O(g)

Because of the toxicity of mercury compounds, mercury(I) chloride is used in antibacterial salves. The mercury(I) ion Hg22+ consists of two bound Hg+ ions.How many grams of mercury(I) chloride are needed to saturate 4900 km3 of water (the volume of Lake Michigan)? (Ksp = 1.5 × 10−18) .

Automobile exhaust often contains traces of ethene (C2 H4), which is another possible product of incomplete combustion. Write a balanced equation for the formation of ethene during the combustion of decane. (Water will also be formed as a product.) (Use the lowest possible coefficients. Omit states of matter.) + +
