Predict and complete two reactions of a compound with water. Use a single arrow to indicate that the reaction proceeds to completion and a double arrow to indicate an equilibrium. Phases (liquid, aqueous, etc.) are optional. Reaction A: H,S + H,O Reaction B: CaH, + 2H,0

The average bond enthalpies of the C¬F and C¬Cl bonds are 485 kJ/mol and 328 kJ/mol, respectively. Given the fact that O2, N2, and O in the upper atmosphere absorb most of the light with wavelengths shorter than 240 nm, would you expect the photodissociation of C ¬ F bonds to be significant in the lower atmosphere?

Step 1: Step 2: Step 3: Step 4: Step 5: 2NO(g) → N202(g) 2H2(g) → 4H(g) N2O2(g) + H(g) → N20(g) + HO(g HO(g) + H(g) → H2O(g) H(g) + N20(g) → HO(g) + N2(g) Intermediate species are N2O2 and N;0 True O False

Chemically and physically describe the combustion of methane CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H20 (g)

What is the major product in the following reaction? Br ·0-

Methyllithium (CH3Li) is often used as a base in organic reactions. Treat any X−Li bond as X−Li+. Draw each of the products of the reaction of methyllithium with ethanol.

Translate the following reaction completely into English words using no symbols:  4NH3 + 5O2 --> 4NO + 6H2O

Because carbon and silicon are both elements in group 14 on the periodic table, we expect them to react with other elements in similar ways. To some extent, they do, but in some cases, carbon and silicon compounds that seem to have analogous structures have very different chemical characteristics. For example, carbon tetrachloride, CCl4, is very stable in the presence of water, but silicon tetrachloride, SiCl4, reacts quickly with water. The unbalanced equation for this reaction is SiCl4 + H2O → Si(OH)4 + HCl Balance this equation. Write a conversion factor that could be used to convert between moles of SiCl4 and moles of H2O. How many moles of SiCl4 react with 24 moles of water? Write a conversion factor that could be used to convert between moles of Si(OH)4 and moles of water. How many moles of Si(OH)4 form when 4.01 moles of H2O react with an excess of SiCl4?
