Explanation:
Just a few things to remember:
- # of neutrons = Mass number - # protons
- Mass number = # protons + # neutrons
- Atomic Number = # of protons
- # of electrons = # of protons - charge on the atom
- Symbol - use the atomic number to find the element in the periodic table
Answer:
Here's what I get
Explanation:
1. Water
The O-H bond in water is highly polar.
It has about one-third ionic character.
The partially-positive H atoms and partially negative O atoms strongly attract each other by hydrogen bonds.
It takes a large amount of energy to separate the water molecules from each other.
Thus, the boiling point of water is relatively high (100 °C).
2. Acetone
The C=O bond in acetone is much less polar.
It is less than 20 % ionic.
The dipole-dipole attractions in acetone are much weaker than the hydrogen bonds in water.
It takes much less energy to separate the acetone molecules from each other.
Thus, even though the molar mass of acetone is more than three times that of water, the boiling point of acetone is only 56 °C.
Answer:
They indicate the condition called Respiratory acidosis
Explanation:
The blood pH in a human range from 7.35 to 7.45 which makes it naturally basic.
The normal range for is
.
Having a pH of 7.25 indicates acidosis and is
which is higher than the normal
This, therefore, indicates respiratory acidosis as the condition of the client because respiratory acidosis is measured by the function of (that is having too much of
in the body)
