Explanation:
Oxides and their hydroxide counterparts made possible the industrial innovations we live in. Indeed, steel is a member of this family. Earth's crust contains them in vast quantities, making them the second most common element.
On a molecular scale, you would find that each oxygen atom is coupled with metal or semimetal atoms that fill in the gaps between them in oxide minerals. Oxides are divided into two groups: simple oxides, with a single metal or semimetal added, and complex oxides, where several metals can be incorporated into the molecule's structure. Hydroxides, on the other hand, are composed of metal ions attached to a highly reactive hydroxide ion (OH). Minerals formed by hydroxide are softer and less dense than oxides and usually form at lower temperatures.
Hey there!
Great question=)
Yes, this statement is true! Propane burns in air and it produces carbon dioxide and water.

B) differences in temperature
Explanation:
The factor that most directly affects the flow of ocean currents is the differences in ocean temperature from one place to another.
Ocean current is the directional movement of the ocean water in its basin.
The main cause of ocean current is differences in temperature.
- Ocean water on the surface receives direct sunlight.
- This warms and the surface and decreases their density.
- When winds blows over them, they cool and sink under their own weight.
- The less cold water in depths rise to replace them.
- This exchange of ocean water due to loss and gain of heat cause ocean current.

Explanation: 4th shell so 4th row and count 7 from the left most column
Answers:
1.
The mole ratio of AlCl₃ to Cl₂ is 2 : 3. This means for production of every 2 moles of AlCl₃ 3 moles of Cl₂ is consumed. Hence, if 3 moles of AlCl₃ is produced then Cl₂ consumed is,
= 3 × 3 / 2
= 4.5 moles of Cl₂
2.
Mole ratio of C₃H₈ to CO₂ is 1 : 3.
Hence, 0.5 moles of C₃H₈ will produce 1.5 moles of CO₂.
Also,
At STP one mole of an ideal gas occupied 22.4 L of volume. Hence, 1.5 moles of CO₂ gas will occupy,
Volume = 1.5 mol × 22.4 L/mol
Volume = 33.6 L of CO₂
