Answer:
D. 6
Explanation:
Each pointy end represents 1 carbon. So in total we have six carbons.
The name of this organic compound is hexane.
Answer:
Igneous Rocks: form by crystallizing melted material (magma).
Explanation:
They can form either on the surface (extrusive igneous rocks), or deep in the crust (intrusive or plutonic igneous rocks).
Answer:
Option 4 ) 1-butyne
Explanation:
In organic chemistry, you should use IUPAC convention in order to name an organic compound. First of all, you should identify the lenght of the organic chain, for this case, you have 5 C atoms, but in fact, you have a triple bond (which would be a substitute: ethynil-) as a substitute, so the main skeleton would have 4 C atoms (a butane)
Then, you start by numbering carbon N° 1 as the one that has the substitute (triple bound)-starting from the right, it would be the second C):
CH₃-CH₂-CH₂-C≡CH
Which will finally leads us to 1-butyne
Answer:
3.076 L.
Explanation:
- The pressure is constant as it is the atmospheric pressure.
- According to Charles’ law; at constant pressure, the volume of a given quantity of a gas varies directly with its temperature.
∴ V₁T₂ = V₂T₁.
V₁ = 2.6 L & T₁ = -11 °C + 273 = 262 K.
V₂ = ??? L & T₂ = 37 °C + 273 = 310 K.
∴ V₂ = (V₁T₂) / T₁ = (2.6 L)(310 K) / (262 K) = 3.076 L.
Answer:
118.75°C is the boiling point of a solution.
Explanation:
Mass of the solute that is barbiturates = 42.5 g
Molar mass of a solute = 184.2 g/mol
Moles of solute =
Mass of the solvent that acetic acid = 825 g = 0.825 kg
Molality of the solution (m):
Elevation in boiling point is given as:
i = 1 (organic compound)
= Boiling temperature of solution.
T = boiling temperature of solvent that is acetic acid=117.9°C
118.75°C is the boiling point of a solution.
