Grade 12 Chemistry Question?

Aluminum Chloride, AlCl3, can be made by the reaction of aluminum with chlorine according to the following equation:2 Al + 3Cl2 2 AlCl3What is the limiting reactant if 20 grams of Al and 30 grams of Cl2 are used, and how much AlCl3 can form?Any help whatsoever is much appreciatedAnd if you could show your work that would be fantasticthanks

450F is safe for Pyrex, but you don't want to bake chicken at that tempI would bake it at 350-375.

glass bakeware should have oven temperature reduced by 25 degrees for best recipe results not to protect the glassware.Glassware holds the heat longer than metals and Pyrex Vision Ware used on stove top can have heat turned off about two thirds of the way once water boils to continue cooking oatmeal etcthe heat is retained and also allows for saving of energy.

I pretty much agree with everyone above except Alex However I notice on the manual that comes with my pyrex dishes, it says not to expose the dish to any temperatures above 400 degreesSo there are many conflicting views about this subjectSo I googled it and what I learned is that any glass dishes such as pyrex cannot take a sudden change of temperatureIt will shock the dish and cause it to shatterWhat gets me is that many recipes say to take a pie plate with the pie crust inside it from the fridge/freezer and put it in a 350 degree hot oven so the p/c won't suddenly slumpThat alarms me and I have never tried itAs the sudden change of temperature will trigger an explosion Again, there are many conflicting views on cooking in pyrex glass dishesShrugThe pyrex website claims glassware products can go directly from refrigerator or freezer to a microwave, convection, or preheated conventional oven.” Since Pyrex is no longer made of the same special thermal shock resistant glass, you should take extra care when using itDo not place Pyrex on your stove topDo not change its temperature rapidly, regardless of what the website says.

Pyrex is oven safe but can not be used on the stove top nor can it be placed under the broilerYou also have to make sure when you remove it from the oven it is placed on a dry surface(if you place the pyrex on a towel that is damp or a wet counter the temperature change may cause the glass to crack) I have used pyrex in an oven that I have set at 450 when I have done oven roasted potatoes.

use molar mass to find moles: 20 grams Al (1 mole / 27 grams Al ) 0.741 moles of Al 30 grams Cl2 (70.9 g/mol Cl2) 0.423 moles of Cl2 by the equation 2 Al + 3Cl2 2 AlCl3 they needed 1.5 X's more moles od Cl2 as compared to moles of Al since they did not add enough Cl2, it is the limiting reagent by the equation: 2 Al + 3Cl2 2 AlCl3 0.423 moles of Cl2 produces 2/3 rd's as many moles of AlCl3 0.282 moles of AlCl3 use molar mass to find grams: ( 0.282 moles of AlCl3) (133.34 grams AlCl3 / mol) 37.6 grams of AlCl3 you might be expected to round that off
