Isotopes= a group of atoms with the same no. of protons , but different no. of neutrons
Hydrogen isotopes
The name of the second isotope is deuterium and the name of the third isotope is tritium(radioactive).The most abundant isotope is
I believe the most appropriate answer would be to change the core from wood to iron. This is because iron is a magnetic material while wood is not magnetic hence cant acquire magnetism. Other factors that would increase the strength of electromagnet would be; increasing the amount of electric current, and increasing the number of windings.
Answer:
2-methoxybutane
Explanation:
This reaction is an example of Nucleophilic substitution reaction. Also, the reaction of (S)-2-bromobutane with sodium methoxide in acetone, is bimolecular nucleophilic substitution (SN2). The reaction equation is given below.
(S)-2-bromobutane + sodium methoxide (in acetone) → 2-methoxybutane
Answer:
P₂ = 3.86 atm .
Explanation:
We assume that during this change , the temperature of the gas remains constant .
So the gas will obey Boyle's law .
P₁ V₁ = P₂V₂
5.08 x 7.56 = P₂ x 9.94
P₂ = 3.86 atm .
<span>the polarity of the solute or the solvent.
for example:
oil will not mix with water because oil molecules are nonpolar however water moleculses are polar. so, they will not mix with each other.
when we put sodium chloride in water, sodium chloride will be easily dissoved. because both sodium chloride and water are polar.
in other case, if we put sodium chloride and hexane together. sodium chloride will not dissove in hexane, because hexane is a nonpolar solvent.
finally, if we try to mix hexane and bromine together, they will mix uniformly. because both hexane and bromine are nonpolar. (note: most diatomic molecules are nonpolar, such as hydrogen gas, oxygen gas, chlorine gas, etc. )
so just remember, nonpolar and nonpolar will dissovle each other. and polar and polar will dissolve each other.</span>
