Chemistry

Answer:

Let's use the example of mail, back in the older days they were most likely transported by people. Until people domesticated the horse, messengers or messenger animals, such as birds, could have been used to transport them. Domesticated animals changed the work force for the better, mail was more efficient but it could still take weeks to get certain letters to far away people. As technology advanced, so did transportation, as of today, tradition mail is brought by mail carriers and is still used. The greatest technological success is the email, and can get mail to another country in a matter of seconds. From mail carriers taking months to deliver letters, to a matter of seconds, technology has paved the way for better communication between people in general.

Hope this helps!

Have a great day and stay safe! :))))))

Industrialization has historically led to urbanization by creating economic growth and job opportunities that draw people to cities. Urbanization typically begins when a factory or multiple factories are established within a region, thus creating a high demand for factory labor.

The celery and carrot will most likely become saltier and perhaps more shriveled because of the high concentration of salt in the water solution compared to the low concentration of salt in the solution. The raisin, however, could take two roots, one would be the same as the carrot and celery, but the other one is it would soak up water because of how salty and shriveled the raisin already is.

Hydrogen sulfide burns form sulfur dioxide:
Helga [31]

Answer: 404.04 kJ.

Explanation:

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

moles of H_2S

\text{Number of moles}=\frac{26.7g}{34.1g/mol}=0.78moles

2H_2S(g)+3O_2(g)\rightarrow 2SO_2(g)+2H_2O(g)    \Delta H=-1036kJ

According to stoichiometry :

2 moles of H_2S on burning produces = 1036 kJ

Thus 0.78 moles of H_2S on burning produces =\frac{1036kJ}{2}\times 0.78=404.04

Thus the enthalpy change when burning 26.7 g of hydrogen sulfide is 404.04 kJ.
