(Code Writing 1) The Heat Index is what the temperature feels like in the context of humidity. For example, if the temperature is 90° F and the relative humidity is 70%, then it feels much warmer - closer to 105° F. Here's the formula for computing the Heat Index HI: HI = C1 + c2T + c3R+ TR+C5T + C&R+ czTºR+CTR+ CgTºR? | X where T is the temperature in °F and R is the relative humidity...

Simple gas laws What is the effect of the following changes on the volume of 1 mol of an ideal gas? (Note: You should NOT need to do any explicit numerical calculations. Use your qualitative understanding of how volume depends on different experimental variables.) The pressure is changed from 2 atm to 760 torr (at constant temperature). （1， 1/2， 1/4，2） Half the gas escapes through a stopcock (at constant temperature and pressure). Answer 2 Both the pressure and the temperature...

T(N)=352 please I need the answer urgent
Question 1 The following gas phase reaction produces ethanol (C2H5OH) by catalytic hydrogenation of acetaldehyde (CH3CHO). The reaction reaches equilibrium at a temperature of T= T(N) and a pressure of 3 bar: CH,CHO(g) + H, (g) C,H,OH (8) The reactive system initially contains 1.5 moles of Hydrogen (Ha) for each mole of acetaldehyde (CH3CHO). The mixture is assumed to be an ideal gas. T(N) is the temperature corresponding to the student number as...

In what follows use any of the following tests/procedures: Regression, confidence intervals, one-sided t-test, or two-sided t-test. All the procedures should be done with 5% P-value or 95% confidence interval. Open Weight_vs_IQ data. SETUP: Common sense dictates that a person’s IQ and Weight should not be related. However, one never knows until one examines the data. Given the data (IQ and weight for 29 students) your job is to check if the common sense assumption is reasonable or maybe it...

1. Consider a dilute solution of molecules at fixed temperature T. These molecules have access to a surface that has a total of B binding sites where molecules can bind. To count states in this system, we will divide space into small cells that each can hold a single molecule. There are a total of B cells that have a binding site, and a total of M cells that do not have binding sites. The overall number of cells is...
