The temperature of the earth gets HOTTER as you get closer to the CORE and COOLER as u move toward the SURFACE.
Not necessarily.
<h3>Explanation</h3>
Isomers might differ in polarities. They will end up with different physical properties such as melting points.
Example:
- 1,2-dichlorobenzene has a melting point of around -18 ~ -17 degrees celsius. (SynQuest)
- 1,4-dichlorobenzene (with two chlorine opposite to each other on a benzene ring) has a melting point of 52 ~ 54 degrees celsius. (SynQuest)
Both 1,4- and 1,2-dichlorobenzene contains two chlorine atoms connected to a benzene ring. The two molecules are structural isomers.
The two chlorine atoms are adjacent to each other in the 1,2 isomer. The molecule is asymmetric and polar.
The two chlorine align with an axis of symmetry in the 1,4 isomer. The molecule is symmetric. The dipoles would cancel out to produce a nonpolar molecule.
Dipole-dipole interactions are typically stronger than <em>induced</em> dipole<em> </em>in isomers. As a result, the 1,2 isomer has a higher melting point.
The balanced reaction
is:
AgNO3 + NaCl = NaNO3 + AgCl
<span>We are given the amount of silver nitrate to react with sodium chloride. This
will be our starting point.</span>
15.0 mol AgNO3 (1 mol AgCl / 1
mol AgNO3 ) =15.0 mol AgCl
The amount of moles produced is the same with the amount of the given reactant since they only one is to one ratio.
Answer:
The pressure changes from 2.13 atm to 1.80 atm.
Explanation:
Given data:
Initial pressure = ?
Final pressure = 1.80 atm
Initial temperature = 86.0°C (86.0 + 273 = 359 K)
Final temperature = 30.0°C (30+273 =303 K)
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
P₁ = P₂T₁ /T₂
P₁ = 1.80 atm × 359 K / 303 K
P₁ = 646.2 atm. K /303 K
P₁ = 2.13 atm
The pressure changes from 2.13 atm to 1.80 atm.
