Determine the molecular formula of a compound that is 49.48% carbon, 5.19% hydrogen, 28.85% nitrogen, and 16.48% oxygen. the mol

Softa [21]

To determine molecular formula, we first need to find out its empirical formula,
Carbon. Hydrogen. Nitrogen. Oxygen
Mass. 49.98g. 5.19g. 28.85g. 16.48g
Mole. 4.165. 5.19. 2.06. 1.03
Divide 4. 5. 2. 1
by
smallest
So by comparing the mole ratio from the table above, i hope u understand the table
The empirical formula is C4H5N2O
given molecular mass = 194.19g
so
(C4H5N2O) n= 194.19
(48+5+28+16)n=194.19
n= 2
molecular formula = C8H10N4O2

What types of questions can be answered through science, and what questions are beyond the boundaries of science? Be specific an

AfilCa [17]

<span>Cause and Effect relationship questions can be answered through science. Science can't answer definite explanations of a question but can show the relationships that they have concluded through research. As an example I did an experiment when I was a kid on mold growing on applesauce if Cinnamon slowed growth or not. I could conclude that there did seem to be a relationship with cinnamon and applesauce that cinnamon slowed growth. I can't say it definitely proved it it just showed the relationship.</span>

Eleven molecules have speeds 15, 16, 17, . . . , 25 m/s. Calculate (a) vavg, and (b) vrms. Part a express your answer with the a

lora16 [44]

The speeds are

15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 m/s.

Vavg = 15 + 16 + 17 + 18 + 19 + 20 +21 +22+ 23+24+ 25 / total molecules = 20 m/s

Vrms = ((sum of square of speed of molecules ) / total molecules )^1/2

Vrms = ( (15^2 + 16^2 + 17^2 + ....25^2) / 11 )^1/2

= (225+ 256 + 289 + 324 + 361+ 400 + 441 + 484 + 529 +576 +625 / 11)^1/2

= (4510 / 11 )^1/2 = 20.25 m /s

2. How do we identify bias and avoid thinking errors when evaluating online<br><br> information?

skad [1K]

Answer:

We can identify bias and avoid thinking errors when evaluating online information when there is a certain degree of partiality in the way the information is given. The writer takes one side and doesn’t consider benefits of the other side/view.

We can identify bias and avoid thinking errors when evaluating online information by making our personal findings and research from other sources and then comparing the two.
