<h2>Heptene formed is -</h2><h2>
</h2>
Explanation:
The two possibilities when the peroxide is not present
+ HBr →
In presence peroxide,
≡
+ HBr →
- When peroxides are present in the reaction mixture, hydrogen bromide adds to the triple bond of heptane with regioselectivity.
- This reaction is opposite to that of Markovnikov's rule which says that when asymmetrical alkene reacts with a protic acid HX, then the hydrogen of an acid is attached to the carbon with more in number of hydrogen substituents, and the halide (X) group is attached to the carbon with more in number of substituents of alkyl.
- One mole of HBr adds to one mole of 1-heptane.
- The structure of heptene formed is -
Answer:
they are use to make tar, asphalt, paraffin wax, and lubricating oils.
Explanation:
The answer would be more heat
<u>Answer:</u> The mass of 
produced will be 8.228 g.
<u>Explanation:</u>
We need to find the mass of carbon dioxide produced when 150 kJ of heat is released.
For the given chemical reaction:
By Stoichiometry of the reaction:
802.3 kJ of energy is released when 1 mole of carbon dioxide is produced.
So, 150 kJ of energy will be release when = 
of carbon dioxide is produced.
To calculate the mass of carbon dioxide, we use the equation:
Moles of carbon dioxide gas = 0.187 mol
Molar mass of carbon dioxide gas = 44 g/mol
Putting values in above equation, we get:
Hence, the mass of produced will be 8.228 g.
In between the two values
Explanation:
Since Calcium is in the same periodic group as both Magnesium and Strontium, the density of calcium will be in between the two values. Calcium, Magnesium and Strontium are all alkali earth metals with two outer electrons.
Calcium is the third element in the group that consists of: Be, Mg, Ca, Sr, Ba and Ra.
- Density is the amount of matter contained in a unit volume of substance.
- Density is directly related to the amount of matter which is the mass of a substance.
- Down a periodic group, the atomic mass increases progressively. The mass of an atom is dictated by the number of protons and neutrons in its nucleus.
- This implies that the density of atoms will increases down a periodic group
- Therefore, it is appropriate to fix the density of calcium between the given values for the two atoms.
