Which statement does NOT apply to Alkenes?
nikdorinn [45]

Answer:

They are more stable than alkanes

Explanation:

  • <em><u>Alkenes</u></em><em><u> are a type of unsaturated hydrocarbons </u></em>which means they have a<u> double bond</u> in their structure, or lack maximum number of hydrogen atoms on each carbon.
  • Alkenes have a general formula of CnH2n. They are called <u>unsaturated hydrocarbons</u> since they have a double bond. They are therefore less stable compared to alkanes and also are readily reactive.

Carvone is a substance that occurs in two forms having different arrangements of the atoms but the same molecular formula (c10h1
Korvikt [17]

The molecular mass of Carvone is calculated as;

                          =  12 (C)₁₀  +  1.008 (H)₁₄  +  16 (O)

                          =  120  +  14.112  +  16

                          =  150.112

%age of Carbon;

                          =  (120 ÷ 150.112) × 100

                          =  79.94 %

%age of Hydrogen;

                          =  (14.112 ÷ 150.112) × 100

                          =  9.40 %

%age of Oxygen;

                          =  (16 ÷ 150.112) × 100

                          =  10.65 %

What amount of heat is required to raise the temperature of 350 grams of copper to cause a 25°C change? The specific heat of cop
jarptica [38.1K]
The heat required to raise the temperature to a specific temperature change of a sample is related to the specific heat capacity of the substance.  In this case, the heat can be calculated through mCpΔT = 350 g * 0.39 J/g C *25 C. This is equal to 3412. 5 Joules. Closest answer is C.

Atmospheric pressure decreases as altitude increases. In other words, there is more air pushing down on you at sea level, and th
Gekata [30.6K]

Answer:

step 2 then step 1 then step 3 then step 4

Explanation:

First boil it. Then identify the situation which is most conducive to boiling .

While this, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.

The liquid will boil when there is weak intermolecular attraction and low atmospheric pressure.

Steps to be followed:

Pentane at high altitude

Hexane at high altitude

hexane at sea level

hexanol at sea level
