Question: Devise ladder programs for systems to carry out the following tasks:
(a) A sequence of four outputs such that output 1 is switched on when the first event is detected and remains on, output 2 is switched on when the second event is detected and remains on, output 3 is switched on when the third event is detected and remains on, output 4 is switched on when the fourth event is detected and remains on, and all outputs are switched off when one particular input signal occurs.
(b) Control of a paint sprayer in a booth through which items pass on an overhead conveyor so that the paint is switched on when a part is in front of the paint gun and off when there is no part. The items are suspended from the overhead conveyor by hooks; not every hook has an item suspended from it.
Draw all stereoisomers having molecular formula C6H12 that contain one double bond and give the IUPAC name for each compound.
a) H2 (g) + Br2 (g) â?" 2 HBr (g) + heat [0.513] [0.62] [0.346] b) N2O4 (g) + heat â?" 2 NO2 (g) [0.0325] [0.022] c) NH4SH (g) â?" NH3 (g) + H2S (g) + heat [0.027] [0.0234] [0.209] Calculate Ke for the following (equilibrium concentrations give..
When 0.633 L of Ar at 1.20 atm and 227°C is mixed with 0.185 L of O2 at 501 torr and 127°C in a 400 mL flask at 27°C, what is the pressure in the flask
During the expansion of 0.9704 mole of CO2 gas, the pressure decreased from 2.304 atm to 1.0 atm. What was the DS (J/K) of the process
what is the final temperature of the block after the evaporation of the alcohol. Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block
Determine the configuration (in the form t2g x egy or ext2y, as appropriate), the number of unpaired electrons, and the ligand-field stabilization energy in terms
Assume the body is all water (so that you use the specific heat of water), and that a person weighs 120 lb. How much the body temperature rise from the heat generated from a serving of Nutella®?
an empty flask has a mass of 123.4 g. when the flask is filled with water the mass is 211.6 g. if 10.0 g of zinc d
In the Fisher Esterification reaction involving an unknown alcohol, acetic acid, and concentrated sulfuric acid (as catalyst), why do we need the sulfuric acid if another acid (the acetic acid) is already present
The free energy change of the conversion of tasmainium to bulgarium was - 60 kcal and the enthalpy of the reaction was determined to be - 9.2kcal.
Formulate a rule/guideline for determining the number of valence electrons from an electron configuration in elements with d electrons present
A 2.00 mole quantity of SO2Cl2 was placed in a 2.4L container. Initially there are no products in the container. At equilibrium it was determined that 49.0% of the SO2Cl2 had dissociated. What is the value of th equilibrium constant under these co..
