P1V1=P2V2
(1.00atm)(3.60L)=(2.50atm)V
3.60=(2.50atm)V
3.60/2.50=V
1.44L=V
The answer is
C. North America
Explanation:
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>
Answer: 10.7 moles
Explanation: Hydrogen gas exists as a diatomic gas (H2) Hence, the Molar mass of one mole of hydrogen gas is 1 x 2 = 2 g. To find the number of moles from the mass take the weight and divide is by the molar mass of the molecule. So in this case, 21.4/2 = 10.7 moles
