Answer:
A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. A diatomic molecule that consists of a polar covalent bond, such as HF, is a polar molecule. The two electrically charged regions on either end of the molecule are called poles, similar to a magnet having a north and a south pole. A molecule with two poles is called a dipole. Hydrogen fluoride is a dipole. A simplified way to depict polar molecules is pictured below When placed between oppositely charged plates, polar molecules orient themselves so that their positive ends are closer to the negative plate and their negative ends are closer to the positive plate
Experimental techniques involving electric fields can be used to determine if a certain substance is composed of polar molecules and to measure the degree of polarity.
For molecules with more than two atoms, the molecular geometry must also be taken into account when determining if the molecule is polar or nonpolar. is a comparison between carbon dioxide and water. Carbon dioxide (CO2) is a linear molecule. The oxygen atoms are more electronegative than the carbon atom, so there are two individual dipoles pointing outward from the C atom to each O atom. However, since the dipoles are of equal strength and are oriented in this way, they cancel each other out, and the overall molecular polarity of CO2 is zero.
Water is a bent molecule because of the two lone pairs on the central oxygen atom. The individual dipoles point from the H atoms toward the O atom. Because of the shape, the dipoles do not cancel each other out, and the water molecule is polar. In the figure, the net dipole is shown in blue and points upward.
Some other molecules are shown below (Figure below). Notice that a tetrahedral molecule such as CH4 is nonpolar. However, if one of the peripheral H atoms is replaced by another atom that has a different electronegativity, the molecule becomes polar. A trigonal planar molecule (BF3) may be nonpolar if all three peripheral atoms are the same, but a trigonal pyramidal molecule (NH3) is polar.
Answer:
Micky Mo is suffering from respiratory acidosis.
Explanation:
The pCO2 level in micky"s body is higher than normal it means the excess amount of CO2 will reacts with water to generate carbonic acid(H2CO3).
On the other hand according to the question total HCO3- also higher than normal.As a result the excess HCO3- will react with proton to form carbonic acid which is in turn dissociate to generate CO2 and H2O to maintain normal acid base homeostasis.
From that point of view it can be said Micky Mo is suffering from respiratory acidosis.
Hi, you have not provided structure of the aldehyde and alkoxide ion.
Therefore i'll show a mechanism corresponding to the proton transfer by considering a simple example.
Explanation: For an example, let's consider that proton transfer is taking place between a simple aldehyde e.g. acetaldehyde and a simple alkoxide base e.g. methoxide.
The hydrogen atom attached to the carbon atom adjacent to aldehyde group are most acidic. Hence they are removed by alkoxide preferably.
After removal of proton from aldehyde, a carbanion is generated. As it is a conjugated carbanion therefore the negative charge on carbon atom can conjugate through the carbonyl group to form an enolate which is another canonical form of the carbanion.
All the structures are shown below.
Answer:
The mass of the air is 6920.71g
Explanation:
Step 1:
Data obtained from the question. This includes the following:
Volume (V) = 5.0x10^3 L
Molar Mass of air (M) = 28.98 g/mol
Temperature (T) = 0.2°C
Pressure (P) = 1.07 atm
mass air (m) =?
Number of mole (n) =?
Recall:
Gas constant (R) = 0.082atm.L/Kmol
Step 2:
Conversion of celsius temperature to Kelvin temperature.
K = °C + 273
°C = 0.2°C
K = °C + 273
K = 0.2°C + 273
K = 273.2 K
Therefore, the temperature (T) = 273.2 K
Step 3:
Determination of the number of mole of air.
Applying the ideal gas equation PV = nRT, the number of mole n, can be obtained as follow:
PV = nRT
1.07 x 5.0x10^3 = n x 0.082 x 273.2
Divide both side by 0.082 x 273.2
n = (1.07 x 5.0x10^3)/(0.082 x 273.2)
n = 238.81 moles
Step 4:
Determination of the mass of air. This is illustrated below:
Number of mole of air = 238.81 moles
Molar Mass of air = 28.98 g/mol
Mass of air =.?
Mass = number of mole x molar Mass
Mass of air = 238.81 x 28.98
Mass of air = 6920.71g
Answer:
all these are physical properties except release of heat so it's probably heat energy given off
