B Very Acidic llllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll
The answer is HCl, C3H6 and C2H5OH. Hydrochloric acid has the lowest boiling point among the three choices since it only has weak dipole-dipole and Van der Waal's forces between molecules which are much weaker than the forces of attraction present in propane and ethanol. Ethanol has the highest since the hydrogen bonding present in ethanol make it hard to break the bonds.
Answer:
3.7 ×10⁴ m
Explanation:
We know that,
1 miles = 1609.34 meter
We need to find how many meters are there in 23.1 miles.
23 miles = 37175.85 m
or
23 miles = 3.7 ×10⁴ m
So, there are 3.7 ×10⁴ m in 23.1 miles.
Molar mass:
H₂O = 18.0 g/mol
O₂ = 32.0 g/mol
<span>C</span>₅<span>H</span>₁₂<span> + 8 O</span>₂<span> -> 5 CO</span>₂<span> + 6 H</span>₂<span>O
</span>
8 x (32 g ) ------------ 6 x (18 g )
mass O₂ ------------ 108 g H₂O
mass O₂ = 108 x 8 x 32 / 6 x 18
mass O₂ = 27648 / 108
mass O₂ = 256 g
hope this helps!
Answer:
Metals have high densities, high melting points, are malleable and ductile, and can conduct heat and electricity.
Hope this helps as well! :)
