Answer:
C₄H₉O₂
Explanation:
just count the amount of atoms present in the model.
Answer:
Try looking for some kind of answer that has to do with .61904
Explanation:
52 g x 1 mol/ (molar mass of aluminum fluoride) 84 g = .619047619
Sorry if this is wrong but that's my best guess
Organic chemistry was definitely harder for me, though this is a matter of opinion and learning style. If you are good with logic, then organic chemistry might not be so hard, or at least that's what my professor said. A lot of physics was just knowing how to use formulas and then plugging and chugging, and knowing basic outcomes of physical reactions. It's a whole other story if you take calculus based physics.
Good luck.
Answer:
→ 
Explanation:
Phosphoric acid is 
and barium hydroxide is 
. Since this is an acid-base reaction, our products should be water and a salt. Put these given compounds together as the reactants:
→ 
We need to balance this by making sure there are the same number of each atom on each side of the equation. Right now, on the left, we have:
- 5 H's
- 1 P
- 6 O's
- 1 Ba
On the right, we have:
- 2 H's
- 2 P's
- 5 O's
- 3 Ba's
To balance this, add a coefficient of 2 to the H3PO4, 3 to Ba(OH)2, and 6 to H2O:
→
Answer:
(b) gas and dust
Explanation:
"The interstellar medium is the stuff between the stars. Made up mostly of hydrogen and helium gas – plus trace amounts of ices, silicate grains, and all the other elements – it contains all the material needed to make stars and planets. It is shaped by stellar winds, dying stars, galactic magnetic fields, and supernova explosions."
"The interstellar medium is filled primarily with hydrogen gas. A relatively significant amount of helium has also been detected, along with smaller percentages of such substances as calcium, sodium, water, ammonia, and formaldehyde . Sizable quantities of dust particles of uncertain composition are present as well."
