Answer:
Molecular Formula: C6H11NaO2
Parent Compound: CID 8892 (Hexanoic acid)
Explanation:
When a mixture of 1−hexanol and hexanoic acid in diethyl ether is shaken with an aqueous NaHCO 3 solution, Hexanoic acid will react with NaHCO 3 to form sodium hexanoate.
CH 3 −CH 2 −CH 2 −CH 2 −CH 2−COOH+NaHCO 3→CH 3−(CH 2 ) 4 −COONa+H 2 O+CO 2
Answer:
Oxidation state of S in SO3^2- is +4
Explanation:
S in SO3^2-=
S = ?
O = -2
S + 3 moles of O * -2 = -2
S + (-6) = -2( it has charge -2)
S - 6 = -2
S = -2 + 6
S = +4
Note, the sign is very important
Don't confuse SO3 together with SO3^2-, the oxidation state of S in SO3 is + 6, how?
S = ?
O = -2
S + 3 * -2 = 0 ( because it has no charge)
S - 6 = 0
S = +6
And in SO3^2-
S = +4
The difference is that one has charge SO3^2- and the other doesn't SO3.
Answer:
The protic solvents are (CH3)2CHOH, NH3, and HCONH2
The aprotic solvent are CH3NO2, CH2Cl2, and N(CH3)3
Explanation:
A protic solvent is a solvent that has a hydrogen atom bound to an oxygen (O), a nitrogen (N), or fluoride (F). Generally, any solvent that contains a labile H⁺ is called a protic solvent.
a. (CH3)2CHOH
(CH3)2CHOH is a protic solvent because one of the hydrogens is bound to oxygen (O)
b. CH3NO2
CH3NO2 is an aprotic (i.e not a protic solvent) solvent because all the hydrogens are bound to carbon.
c. CH2Cl2
CH2Cl2 is an aprotic solvent because all the hydrogens are bound to carbon.
d. NH3 is a protic solvent because all the hydrogens are bound to Nitrogen (N)
e. N(CH3)3 is an aprotic solvent because all the hydrogens are bound to carbon
f. HCONH2 is a protic solvent because two of the hydrogens are bound to Nitrogen (N)
Explanation:
1) Boyle's Law: This law states that pressure is inversely related to the volume occupied by the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
- When the size of the chamber is increased the volume occupied the gas will increase with which pressure exerted by the gas will decrease down.
- When we press the inflated balloon the pressure on the gas is increased with which volume of the occupied by the gas inside the balloon decreased.
2) Charles' Law: This law states that volume occupied by the gas is directly related to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
- The size of the balloon deceases because the in winters the temperature decreases with which volume of the gas present in the balloon also decreases.
- When the flexible closed container is heated the temperature of the gas inside the container increases with which the volume occupied by the gas in the container will increase resulting in expanding of container.
3) Avogadro's Law: This law states that volume occupied by the gas is directly related to the number of moles of the gas at constant pressure and temperature.
(At constant temperature and pressure)
When we blow air into the balloon the umber of air particles increases with which the volume of the gas inside the balloon also increases resulting in increase in size of the balloon.
The mass of sample = 10 g

Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density , g/ml
m = mass , g
v = volume , ml
Density is 5 g/ml and sample is 2 ml,so :
ρ = 5 g/ml
V = 2 ml
The mass :
