Answer:
The three major types of bond are ionic, polar covalent, and covalent bonds. Ionic occurs majorly between metals and non-metals, which allows sharing of electrons to form an ionic compound. Whereas covalent bonding calls for complete transfer of electrons between atoms. Polar covalent bonds have unequaly shared electron-pair between two atoms.
Explanation:
a. Cu (Copper)-<em> ionic bonding
</em>
b. KCl (Potassium Chloride)
- <em>ionic bonding
</em>
c. Si (Silicon)
- <em>covalent bonding
</em>
d. CdTe (Cadmium Telluride)
- <em>polar covalent bonding
</em>
e. ZnTe (Zinc Telluride)- <em>polar covalent bonding
</em>
Water is a very good solvent due to its very polar nature. A polar substance is one where the atoms within the molecules of the substance carry partial charges. Oxygen is very electronegative, so it induces partial charges within the bonds of the water molecule. The extremely polar nature of water, along with its ability to make hydrogen bonds, ensure that it is able to dissolve a variety of substances.
Answer:
The answer to your question is: Flask X
Explanation:
Data
Flask X Flask B
Molar mass 30 g 60 g
mass 1.2g 1.2 g
Pressure 1 atm 0.5 atm
Formula PV = nRT
In the formula, we can notice that the number of moles (n)
is directly proportional to the pressure.
Then, let's calculate the number of moles
flask X flask Y
30 g --------------- 1 mol 60 g -------------- 1 mol
1.2 g ---------------- x 1.2 g ------------- x
x = (1.2 x 1) / 30 x = (1.2 x 1) / 60
x = 0.04 mol x = 0.02 mol
From the results, we conclude that the flask with the gas of molar mass 30g is the flask with pressure of 1 atm, because the higher the number of moles, the higher the pressure.
