Answer: It would be Sp2, because H3O+ has planar structure.
Answer : The millimoles of acetate need to add to this solution will be, 18.2 mmol
Explanation :
For acetic acid,
Moles of of acetic acid = 10 mmol
pH = 5.00
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Thus, the millimoles of acetate need to add to this solution will be, 18.2 mmol
The characteristic of the compound you are referring is essential to where on the functional groups it belong. Furthermore, the basic functional groups among the hydrocarbons are: alkane, alkene, alkyne, benzene, and others that basically has a hydrogen atom and a carbon atom.
Transcript of Physical and Chemical changeswhen baking a cake. The first change that occurs when you are baking a cake is a physical change. When you pour the cakebatter in to the pan/bowl, then add the water, the batter only changes its appearance from a solid to a liquid
Answer:
moles
Explanation:
We are given:
Vapor pressure of water = 19.8 torr
Total vapor pressure = 752 torr
Vapor pressure of oxygen gas = Total vapor pressure - Vapor pressure of water = (752 - 19.8) torr = 732.2 torr
To calculate the amount of oxygen gas collected, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 732.2 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 732.2 / 760 atm = 0.9634 atm
V = Volume of the gas = 23 mL = 0.023 L
T = Temperature of the gas =
R = Gas constant =
n = number of moles of oxygen gas = ?
Applying the equation as:
0.9634 atm × 0.023 L = n × 0.0821 L.atm/K.mol × 295.15 K
⇒n = moles
