Answer:
T₂ = 464.75 K
Explanation:
Given data:
Initial Temperature = 398.15 K
Pressure = 248 torr (constant)
Initial Volume = 275 mL (275/1000 = 0.275 L)
Final volume = 0.321 L
Final temperature = ?
Solution:
V₁/T₁ = V₂/T₂
T₂ = V₂ T₁ / V₁
T₂ = 0.321 L × 398.15 K / 0.275 L
T₂ = 127.81 L.K / 0.275 L
T₂ = 464.75 K
The product of the reaction between lithium hydroxide and hydrofluoric acid is
lithium fluoride (LiF) and water(H₂O)
<u><em>Explanation</em></u>
Base react with acid to form salt and water.
Lithium hydroxide( <em> a base</em>) react with hydrofluoric acid (<em> an acid</em>) to produce lithium fluoride( <em> salt)</em> and water according to reaction below
Answer:
the fossils on some of the continents were in the same spots as fossils on other continents
Explanation:
tell me if i need to explain more. x
A—3 protons, 4 Neutrons, 3 electrons
Moles of
= 6.5 mol
mole ratio of <span>
: HCl = 1 : 2
</span>∴ since <span>
cntain 6.5 mol, then HCL contains (2 * 6.5) mol
Thus moles of HCl = 13.0 </span><span>mol
Volume of HCl needed = </span>
=
<span>
</span><span> = 8.67 </span>
<span>then volume of HCL needed = 8.67 L
</span>
