The following system is at equilibrium in a closed vessel: 4 HCl(aq) + MnO2(s) ⇆ MnCl2(aq) + 2 Cl2(g) + 2 H2O(l) Various stresses are applied to the system as illustrated in the chart. Drag the appropriate label from the list below that indicates how the system responds to each stress. Each label can be used more than once.

There is something wrong with my answers but I can’t pinpoint where I made a mistake. please help.

4 o When burning ethanol in a closed system, which of the following is the best claim and reasoning? The ethanol reaction stops because a bromthymol blue solution that's present turns the same color as when ethanol vapor is blown into the solution. O Water is produced because a bromthymol blue solution that's present turns the same color as when water vapor is blown into the solution. O Evaporated ethanol is produced because it burns. Carbon dioxide is produced because a bromthymol blue solution that's present turns the same color as when carbon dioxide is blown into the solution. 1 2 4. 6 7 8 Next acer

The following system is at equilibrium in a closed vessel: 2 CH4(g) ⇆ C2H6(g) + H2(g) Various stresses are applied to the system as illustrated in the chart. Drag the appropriate label from the list below that indicates how the system responds to each stress. Each label can be used more than once. Sorry, that's incorrect. Try again?

One application of adsorption on surfaces is to measure the ability of acti- vated charcoal to adsorb acid. (Activated charcoal, a form of treated carbon, is very porous and is used to adsorb impurities from water. Its use in aquar- iums typifies this behavior.) In a lab experiment, a student mixes a given amount of powdered charcoal into a series of acetic acid solutions. The acetic acid solutions have different initial concentrations. Some of the acid is ad- sorbed onto the charcoal. By taking aliquots after equilibrium is established, the student determines the change in acid concentration. Plot a Langmuir isotherm for the experimental data and determine the equilibrium constant for the adsorption. The experimental data are as follows: Original concentration (M) 0.7001 Change in concentration (M) 0.3694 0.1515 0.0437 0.0169 0.00665 0.00588 0.00553 0.00283 0.00153

Review I Constants i Perlodic Table As a food chemist for a major potato chip company, you are responsible for determining the salt content of new potato chip products for the packaging label. The potato chips are seasoned with table salt, NaCl. You weigh out a handful of the chips, boil them in water to extract the salt, and then filter the boiled chips to remove the soggy chip pieces. You then analyze the chip filtrate for Cl- concentration using the Mohr method.First you prepare a solution of silver nitrate, AGNO3, and titrate it against 0.500 g of KCl using the Mohr method. You find that it takes 64.5 mL of AgNO3 titrant to reach the equivalence point of the reaction. You then use the same silver nitrate solution to analyze the chip filtrate in a Mohr reaction, finding that the solution yields a rusty brown precipitate when 45.4 mL of titrant is added. Part A If the sample of chips used to make the filtrate weighed 76.5 g , how much NaCl is present in one serving (105 g ) of chips?…

Construct the expression for Kc for the following reaction. CO(g) + 2 H2(g) = CH3OH(g) 1 Drag the tiles into the numerator or denominator to form the expression. Each reaction participant must be represented by one tile. Do not combine terms.

Please help and make sure that the significant figures are correct. Thank you in advance!

please solve part (c)
