Answer:

As per Provided Information

Distance travelled by sound impulse through an aluminium rod is 1500 metres .

We have been asked to determine the time taken by the sound impulse to travel through aluminium rod .

As we know

Speed of sound in aluminium rod is 5100m/s .

Using Formulae 

 $\boxed{\bf \: Time \: taken_{(Sound \: impulse)} = \cfrac{distance \: travelled \: by \: sound \: impulse}{speed \: of \: sound \: impluse}}$ 

Substituting the value and we obtain

$\sf \qquad \longrightarrow \: Time \: taken_{(Sound \: impulse)} = \dfrac{1500}{5100} \\ \\ \\ \sf \qquad \longrightarrow \: Time \: taken_{(Sound \: impulse)} = \cancel\dfrac{1500}{5100} \\ \\ \\ \sf \qquad \longrightarrow \: Time \: taken_{(Sound \: impulse)} = 0.29 \: s$

Therefore ,

0.29 second sound impulse takes to travelled.

So, your answer is 0.29 s .

Answer:

(a) Increasing the temperature adds heat which is a reactant shifting the equilibrium rightwards.

(b) Pressure has no effect since the change in the number of moles is zero.

Explanation:

Hello,

In this case, one could represent the given reaction as:

$N_2(g)+O_2(g)+ \Delta _rH \leftrightarrow 2NO$

Since it is endothermic. Thus, solving the (a) statement, one identifies the heat as a reagent, that is why the reaction cools down as it progress, therefore, by increasing the temperature, heat is added, that is, a reagent is added, which shifts the equilibrium rightwards, in other words, more NO is produced so its concentration increases.

Furthermore, for the (b) statement, since the change in the number of moles is zero, based on the stoichiometric coefficients as shown below:

$\Delta \nu =2-1-1=0$

Such value implies that the pressure has no effect on the concentration, taking into account the following form of the law of mass action:

$Kp=Kc(RT)^{\Delta \nu }$

Thus, since $\Delta \nu =0$ , $Kp=Kc$ , so no effect in concentration is due to the pressure.

Best regards.

Which pair of atoms would form a covalent bond ?

Liula [17]

I think O and Cl will form covalent bonds since they are both non-metals and don't have a large enough difference in electronegativities to create an ionic bond.

I hope this helps. Let me know if anything is unclear.

The freezing temperatures for water for Celsius and Fahrenheit scales are 0ºC and 32ºF. The boiling temperatures for water are 1

ddd [48]

Answer:

Therefore the required function is

$C= \frac{5}{9} (F-32)$

Therefore 25°C=57°F

Explanation:

F denotes temperature of Fahrenheit and C denotes temperature of Celsius.

$\frac{C-0}{100-0} =\frac{F-32}{212-32}$

$\Rightarrow C= \frac{100}{180} (F-32)$

$\Rightarrow C= \frac{5}{9} (F-32)$

Therefore the required function is

$C= \frac{5}{9} (F-32)$

Putting C=25°C in above equation

$25=\frac{5}{9} (F-32)$

$\Rightarrow 25 \times \frac{9}{5} = F-32$

⇒45 =F-32

⇒F=32+45

⇒F=57

Therefore 25°C=57°F
