Answer:
5)HOCH2CH2OH
Explanation:
This is also known as ethylene glycol. An increase in hydrogen bonds of a compound means an increase in the viscosity. Hydrogen bonds occur as a result of bonding with electronegative elements such as Oxygen, Nitrogen etc.
The compounds with the highest amount of Hydrogen bond represents the one with the highest viscosity which is B) HOCH2CH2OH
Answer: Missing data related to question is attached below
If the KH,CH4 = 1.42 * 10^-3 mol/L atm
answer:
0.88 atm
Explanation:
P1 = 20 psi
aqueous concentration of methane in closed bottle = 20 ppm
20 ppm = 20 / 1000 ( gram / Kg ) = 0.020 gram/kg = 0.020 g/liter
molar mass of methane = 16 gram/mol
<em>next : convert mass conc to molar conc </em>
Cm = 0.020 / 16
Cm = 1.25 * 10^-3 mol/L
Given that KH,CH4 = 1.42 * 10-3 mol/L atm
Applying equilibrium relationship
Cm = ( KH,CH4 ) ( partial pressure of methane )
hence partial pressure of methane
= Cm / ( KH,CH4 ) = 1.25 * 10^3 / (1.42 * 10^-3 ) = 0.88 atm
Answer:Rocket is lauched for first one, Second one is the wagon one and third one is seabelt impact.
Explanation:
Answer: Option (C) is the correct answer.
Explanation:
According to Arrhenius, bases are the species which when dissolved in water will give hydroxide ions, that is, 
.
For example, 
Arrhenius acids are the species which when dissolved in water will give hydrogen ions, that is, 
.
For example, 
In water, when an acid loses a hydrogen ion then the specie formed is known as conjugate base.
Here, 
is the conjugate base of 
.
Similarly, species which accept the hydrogen ion result in the formation of conjugate acid.
Hence, 
is the conjugate acid of 
.
Thus, we can conclude that is the conjugate base.
