Which of the following statements best describes the concept of a function?

tiny-mole [99]

Functions in programming parlance refers to a logical and unique way of bundling a set of instructions together into one handy and single program which can be reused in other programs.

Functions are a very important concept of programming as they allow a task to be written once and could be called in an <em>infinite amount of time when needed</em>.

They take a function name and optional argument. The syntas for writing functions any differ from one programming language to another.

A: name at least two indicators that a driver must not turn right at this intersection.

suter [353]

A: Name at least two indicators that a driver must not turn right at this intersection these are Indicator lighting are amber in color and may be positioned on the front, the rear and every so often on the aspect of the automobile on each the left and proper-hand sides.

<h3>When the 2 roads intersect on the site visitors mild flip proper?</h3>

If each car are turning properly then they do not want to move every other's paths. When you return back to an intersection and the street past is full of cars going withinside the identical route you have to wait till there's room to absolutely move the intersection, even in case your site visitors mild turns green.

Indicator lighting are amber in color and may be positioned on the front, the rear and every so often on the aspect of the automobile on each the left and proper-hand sides. You use your signs to expose an meant extrude of the route, whether or not turning left or proper or transferring out into site visitors.

Kp for the following reaction at a give temperature is 0. 263 at 1000. K: c(s) + 2 h2(g) ⇌ ch4(g) what is the total pressure (in

ratelena [41]

This problem is providing us with the reaction whereby methane is produced from solid carbon and gaseous hydrogen, as well as its Kp and asks for the total pressure at equilibrium for a specified addition of reactants. At the end, the answer turns out to be 11.7 atm.

<h3>Chemical equilibrium</h3>

In chemistry, when a chemical reaction takes place, it proceeds until a point called equilibrium, where the concentration of all the species start becoming unchanged. Thus, we can use equilibrium expressions whenever we needed pressures or concentrations at equilibrium.

In this case, for the reaction we were given, we can write the following equilibrium expression, where the solid carbon is excluded:

$Kp=\frac{p_{CH_4}}{p_{H_2}^2} =0.263$

Which can also be written in terms of the reaction extent and the initial pressure of hydrogen:

$0.263=\frac{x}{(p_{H_2}^0-2x)^2}$

Thus, we calculate the initial pressure of hydrogen with the temperature and volume of the flask:

$p_{H_2}^0=\frac{(4.50g/2.02g/mol)*0.08206\frac{atm*L}{mol*K}*1000K}{10.0L}\\ \\p_{H_2}^0=18.3atm$

Hence, we solve for x in the equilibrium expression as follows:

$0.263=\frac{x}{(18.3-2x)^2}\\\\x_1=6.64atm\\\\x_2=12.6atm$

Where the correct value is 6.64 atm because the 12.6 atm turns out into a negative pressure for hydrogen at equilibrium. Finally, we calculate the total pressure with:

$P_T=p_{CH_4}+p_{H_2}=x+18.3-2x\\\\P_T=6.64atm+18.3atm-2*6.64atm\\\\P_T=11.7atm$
