Answer:
We in daily life use technology to pay virtually through virtual wallets, work at home, purchase packages to travel abroad, many businesses handle virtual advertising, that is why it is called the new "market window" to social networks or internet pages, university universities playful methods through virtual campuses or virtual classes.
The serious impact is very great since many of the activities of daily life change, and they will return to being as before the technology affected in our lives, reversing customs and technological generations.
The new technologies are: computer science, engineering, arquetectonica, scientific, industrial, commercial ... Where a fourth industrial revolution arises where many processes that were carried out by humans today would be automated by computers or technological devices that improve market efficiency, of consumption and industrialization.
Explanation:
In addition, new technologies are those that are based on electronic devices that are based on social communication, the development of social networks and technology based on global communications.
I believe it would be a compound
Answer:
It is a chemical change
Explanation:
Fat is a triglyceride. Triglycerides form soap when they come into contact with sodium hydroxide.
Now, we know that a chemical change is one in which a new substance is formed and it is not easily reversible. Heat is also given out or absorbed in the process.
Now the combination of sodium hydroxide and fat yields a new substance called soap. The appearance of the new substance conclusively proves that a chemical change has taken place.
Answer:
Molar mass of H3PO4 = 97.99 g/mol (Approx.)
Explanation:
Find:
Molar mass of H3PO4
Given;
Molar mass of H = 1.0079 g/mol
Molar mass of P = 30.974 g/mol
Molar mass of O = 15.999 g/mol
Computation:
Molar mass of H3PO4 = (1.0079)(3) + 30.974 + 15.999(4)
Molar mass of H3PO4 = 3.0237 + 30.974 + 63.996
Molar mass of H3PO4 = 97.9937
Molar mass of H3PO4 = 97.99 g/mol (Approx.)
