Answer:
Heptane (d) > Hexane (b) 3,3 dimethyl pentane (c) > butane (a)
Explanation:
<u>The boiling points of the alkanes are depends on the following factors:</u>
- Hydrocarbons with strong intermolecular forces have high boiling points.
- Longer carbon chain molecules have high boiling points.
- Straight chain hydrocarbon molecules have high boiling points than the branched chain hydrocarbons molecules because straight chain molecule have large surface area.
The given molecules are as follows.
a) Butane
b) Hexane
c) 3,3 dimethyl pentane
d) Heptane.
The Highest to lowest boiling point order is as follows.
Heptane (d) > Hexane (b) 3,3 dimethyl pentane (c) > butane (a)
Answer:
option D
Explanation:
Increasing the temperature increases the yield of ammonia and speeds up the reaction as chemical reaction is affected by temperature.
The balanced equation :
LiI(aq) + AgNO₃(aq) --> AgI(s) + LiNO₃(aq)
<h3>Further explanation</h3>
Given
Word equation
Required
Balanced equation
Solution
There are 3 ways to express a chemical equation:
- word equation
- skeleton equation
- balanced equation
Skeleton equation for reaction above :
LiI(aq) + AgNO₃(aq) ⇒ AgI(s) + LiNO₃(aq)
If we look at this reaction, all the cations and anions have a charge of 1 (+1 or -1) so the balanced reaction between the skeleton equation and the balanced equation is the same
