Nii2O3( s)→Ni(s)+O2( g) a. Two clear, colorless liquids are added together, and the resulting solution becomes warm. D) All of the above are true. Verified Solution. 1.0 e. When solid potassium chlorate is heated, it decomposes to form solid potassium chloride and oxygen gas. CH4 (g) + O2 (g) → 2H2O(g) + CO2 (g) O2 (g) CH4 (g) CO2 (g) H2O (g) Both O2 (g) and CH4 (g), Given the data in the CH4 + 1 O2 CO2 +2 H2O.3 According to the first law of thermodynamics A) Energy is neither lost nor gained in any energy transformations. O2 c. One gram of methane gas reacts with two grams of dioxygen gas, producing one gram of carbon dioxide gas. a.10 mol 1. More specifically, we see that 1 mole of methane produces 1 mole of carbon dioxide. Identify all of the phases in your answer.8 moles of methane are allowed to react with 3 moles of oxygen, what is the limiting reactant? Chemistry Stoichiometry Limiting Reagent. 2532.0 L of CH4 (g) at STP to produce CO2 (g) and H2O (g)? Given: CH4 (g) + 2O2 (g) → CO2 (g) + H2O (g) I'm not really sure how to approach this problem.0 g of O2 at 305 K. C(s)+O2(g)2CO2(g)→CO2(g)→2CO(g)+O2(g)ΔHΔH=−394 kJ=+283 kJ Your answer should have three significant figures. The unbalanced equation for this reaction is CH4(g)+O2(g)→CO2(g)+H2O(g) What coefficients are needed to balance the equation for the complete combustion of methane? Enter the coefficients in the order CH4, O2, CO2, and H2O, respectively. Ca (s) + 2HI (aq) → CaI2 (aq) + H2 (g) A) Ca is reduced Study with Quizlet and memorize flashcards containing terms like The air exhaled from the lungs of a smoker has a concentration of 325 ppm CO.
