Answer the following statement(s) true (T) or false (F)
A. The new equilibrium system will contain more C, D and E because higher pressure always favors the products in any reaction equilibrium. B. The new equilibrium system will contain more C because higher pressure favors the products in the first reaction. The amounts of D and E will be unchanged, since pressure doesn’t affect the equilibrium of the second reaction. C. The new equilibrium system will have more C because higher pressure favors the products in the first reaction. The amounts of D and E will be lower, because the consumption of more A by the first reaction will cause the second reaction to generate more of it. D. The new equilibrium system will contain no A because both reactions consume it and the first reaction favors C at higher pressures. E. Insufficient information to solve.
Even if you are drawing plans for a construction site where seismic risk is high, you can alter window placement depending on whether an engineer supervises the design or the design follows the prescriptive path of the IRC.
Answer the following statement true (T) or false (F)
The preferred practice is to align an auxiliary view with its principal view when possible, which generally makes it easier to read the print. However, there is an option to rotate an auxiliary view when the normal auxiliary view placement takes up too much space on the sheet. When this is done, a viewing-plane line is used to indicate from where the view is taken, and the auxiliary view is placed in any desired location on the sheet. The auxiliary view is rotated as needed and the angle and direction of rotation is specified under the view title.
