Which statement is correct about the compound B? Al4C3(s) + 12H20(l) ----> 4Al(OH)3(s) + 3CH4(g) If 125g of aluminum carbide is decomposed, what is the theoretical yield of methane? A. Same happens with alumnium carbide also. Metallic carbide on treatment with water gives out a colourless gas which burns readily in air and gives a red precipitate with Cu2Cl2 + NH4OH. Calcium carbide on treatment with water gives a hydrocarbon(A). The 5g values of the MozN samples, both the origi- nal and the sintered ones, are retained in the case of CH4-H2 treatment. Complete the formula of the carbide below, and balance the equation for the reaction: _Al_C_ + _H2O --> _Al(OH)3 + _CH4. And, the average American family of four uses 400 gallons (1514 L) of water per day. Convert all quantities in moles. 0.6 moles of carbide reacted with excess water to give 2.4 moles of Al(OH)3 and 1.8 moles of CH4. Divide that by water's molecular weight (gives 55,5 mol). The gas is a) CH4 b) C2H6 c) C2H4 d) C2H2 40. Hydrolysis of magnesium carbide. Define the term âcatenationâ. Name a compound which will give acetylene gas when treated with water. Silicon carbide reacted with H 2 O to yield amorphous S i O 2 and C H 4 by the reaction, S i C + 2 H 2 O S i O 2 + C H 4 above 5 0 0 0 C. The rate of oxidation of silicon carbide was studied at different partial pressures of water vapour. Answer: It is the property of elements by virtue of which atoms of the element can link to each â¦ Magnesium carbide react with water. (A) It is antiaromatic in nature (B) The degree of unsaturation of compound is 4 (C) The compound B gives bromine water test Find another reaction. Divide 3.50kg by the molecular weight of CaC2 (gives 54.68 mol). The GC system incorporates the reaction cell (RC), where the sample is treated with calcium carbide to form acetylene, followed by an electrically actuated 6-port sampling valve (SV) and the analytical column filled with 15% PEG-600/PTFE to separate the acetylene from the ammonia matrix. Our channel. Which one of the following compounds gives methane on treatment with water? When acetylene reacts with 10% H2SO4 in the presence of HgSO4 yields a) CH3OH b) CH3COOH c) CH3CHO d) CH3OCH3 41. The density of water (supposing STP conditions) is 1 so 1L=1kg. Answer: CaC 2; (calcium carbide) 2005. Aluminum carbide, Al4C3, reacts with water to produce methane. This implies similarity between Be and Al. Second, for a given oxide to carbide transformation, the CH4-graphite equilib- rium curve gives the CH4 concentration that should be used to avoid polymeric car- bon deposition. Beryllium carbide on hydrolysis gives methane. Aluminium carbide contains only aluminium and carbon. It reacts with water to give Aluminium Hydroxide, Al(OH)3, and methane, CH4. First, we need to know what percentage of the air in their house would contain methane. If only 13.6g of methane is obtained, what is the percent yield of this gas? BeâC + 4HâOââ>2Be(OH)â + CHâ Mg 2 C 3 + 4H 2 O â 2Mg(OH) 2 + C 3 H 4 [ Check the balance ] Magnesium carbide react with water to produce magnesium hydroxide and propyne. In- deed, the nitride-to-carbide transformation does not change the crystallite size. With CH4 alone, the 5g of W2N and Mo2N decrease due to clogging of the pores, known to be narrow (24), rather than to sintering. Question 1. For the sake of argument, let's assume the worst: All 70 mg of methane (CH4) per liter of water escape into the air. 4 moles of A on heating along with [Ni(CN)4, gives a. product B.
