b. and the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.
c. and the hydrogen atom of allyl alcohol that is covalently bonded to the carbon atom.
d. Actually, hydrogen bonding is NOT the intermolecular force between allyl alcohol and
water
10) The hydrogen bonding interaction between particles of allyl alcohol and water
occurs between the oxygen atom of water
a. and the oxygen atom of allyl alcohol.
b. and the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.
C. and the hydrogen atom of allyl alcohol that is covalently bonded to the carbon atom.
d. Actually, hydrogen bonding is NOT the intermolecular force between allyl alcohol and
water
Hydrogen bonding interaction occurs between the oxygen atom of water and the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.
We must recall that allyl alcohol is a molecular substance. Molecular substances do not dissociate into ions in water. As such particles of allyl alcohol remain intact when dissolved in water.
Hydrogen bonding occurs when hydrogen is bonded to an electronegative atom such as oxygen. In allyl alcohol, hydrogen bonding interaction occurs between the hydrogen atom of water and the oxygen atom of allyl alcohol.
Also, hydrogen bonding interaction occurs between the oxygen atom of water and the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.

28) what is the number of oxygen atoms in the formula unit of Ca3(PO4)2?
Answer:
4.816x10²⁴atoms
Explanation:
the number of moles of oxygen is 8
let x be number of oxygen atoms
recall that 1 mole=6.02x10^23 atoms
therefore, 8 moles =x
cross multiply
8 x 6.02 x 10^23 = x
x = 4.816 x 10²⁴atoms
5.27x10^45 molecules of h20 is how many moles
Answer:
6.02 × 10^23 molecules = 1 mole
5.27 × 10^45 molecules = x
x = 5.27 × 10^45/ 6.02 × 10^23 × 1
= 8.754 × 10^21 mol

As the ionic compound increases in
complexity, the melting point
A. increases
B. decreases
C. stays the same
Given what we know, we can confirm that as an ionic compound grows more complex, its melting point will increase.
What is an Ionic compound?An ionic compound is one in which atoms of elements share electrons between them to form compounds.These shared electrons generate powerful electrostatic forces that we refer to as ionic bonds. Electrostatic forces cause an increase in the melting point of a compound. As a compound grows more complex and adds more elements to its composition, it will gain new electrostatic forces, and thus increase its melting point.Therefore, as an ionic compound grows more complex, its melting point will increase due to the increasing number of strong electrostatic forces present in the compound.

Answer:
211.0
Explanation:
∆G(free energy) = ∆H(enthalpy) - T∆S(entropy)
∆H = 215KJ/mol
T = 90°C = 273 + 90
= 363K
∆S = 11J/mol/K or 11 × 10^-3kJ/mol/K
∆G = 215- 363(11 × 10^-3)
= 215 - 3.993
= 211.007
To the nearest tenth 211.0

Example #1 write the chemical formula for Calcium Oxide
Step 1
-Find the Atomic symbol of the metal and non-metal on the periodic table
CaO
Step 2
Find the charges for Calcium and Oxygen
which are Ca 2+ and O 2-
Step 3
Balance out the charges
They are already balanced out
Here´s the chemical formula for Calcium Oxide
CaO
Example 2 write the chemical formula for Aluminum Oxide
Step 1
-Find the Atomic symbol of the metal and non-metal on the periodic table
A
l
O
Step 2
Find the charges for Aluminum and Oxygen
Which are Al 3+ and O 2-
Step 3
Balance out the charges
You need 2 Aluminum and 3 Oxygen to balance the charges
Al 3+ O 2-
Al 3+ O 2-
= 6 + O 2-
= 6-
Step 4
If you need more then one element to balance out the charges you identify that by using subscripts

A. Groundlings
B. Quantums
C. Spectrums
D. Amplitudes
A spectrum is a pattern is unique to a substance and can be used identify it.
According to Max Plank, energy occurs in packets called quanta. Hence, energy is not continuous but takes on discrete values which are integer multiples of a fundamental amount.
Again, when a substance is given light energy, a characteristic fingerprint is obtained. This pattern is unique to the substance that has it. These characteristics “fingerprints” are called spectrums.
