Answer:
what do u need help with?
Explanation:
Answer:
1.5g
Explanation:
Remember that Molarity = (#moles of solute)/(#liters of solution)
This problem informs us that the Molarity of the vinegar is 0.84 and that the solution is 15mL.
First let's get your SI units to the correct ones.
15mL (1L/1000mL) = 0.015L
Molarity = (#moles of solute)/(#liters of solution) ~
(Molarity)(#liters of solution) = #moles of solute
(0.84M)(.015L) = 0.0126moles of acetic acid per tablespoon
2 tablespoons a day = 0.0126moles*2 = 0.0252 moles of acetic acid.
Now that we have the # of moles of acetic acid we need to get our answer into grams. The molecular weight of HC2H3O2 is 60g/mole.
0.0252mole HC2H3O2 (60g HC2H3O2/1mole HC2H3O2) = 1.512g ~ 1.5g HC2H3O2.
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.
Answer : The oxygen will appears in the final chemical equation as a reactant.
Explanation :
The given chemical reactions are:
(1) 
(2) 
Now we are adding reaction 1 and reaction 2, we get the final chemical equation.
The final chemical equation is:
Thus, the oxygen will appears in the final chemical equation as a reactant.
