Answer: The new volume of gas is 28.5 L
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 1.00 atm (at STP)
= final pressure of gas = 102.6 kPa = 1.01 atm (1 kPa= 0.0098 atm)
= initial volume of gas = 10.0 L
= final volume of gas = ?
= initial temperature of gas = 
(STP)
= final temperature of gas = 
Now put all the given values in the above equation, we get:
The new volume of gas is 28.5 L
b is fastest, having the lowest activation energy (35 kJ) and is an exothermic reaction, releasing energy in the form of heat
c is slowest, having the highest activation energy (55 kJ) and is an endothermic reaction, taking in energy from its surroundings
Stearic acid formula is CH₃(CH₂)₁₆COOH
The molecular mass of stearic acid is 284.48 g/mol
The mass of stearic acid in 1 ml of solution is 0.1 g
Therefore number of moles in 1 ml is - 0.1 g / 284.48 g/mol = 0.000352 mol
Molarity is number of moles in 1 L of solution
If 1 ml contains - 0.000352 mol
Then 1 L solution contains - 0.000352 /1 x 1000 = 0.352 mol/L
Therefore molarity is 0.352 M
Answer:
An emulsifying agent is typically characterized by having <u><em>d. one polar end and one nonpolar end.</em></u>
Explanation:
Emulsifiers are substances that have the ability to bind, for example, fats with those substances that have mostly water in their conformation. In other words, the emulsifier facilitates mixtures of two or more immiscible liquid substances.
This is because the molecules of an emulsifier are often lipophilic (attract oil) at one end and hydrophilic (attract water) at the other. In other words it consists of a polar (hydrophilic) head group and a non-polar (hydrophobic) tail.
<u><em>An emulsifying agent is typically characterized by having d. one polar end and one nonpolar end.</em></u>
