Answer:
See explanation
Explanation:
From left to right, the oxides across period 3;
i) Period 3 oxides all appear white in colour. They are all crystalline solids and their melting points decrease from left to right.
ii) The volatility of period 3 oxides increases from left to right across the periodic table
iii) The metallic oxides on the right hand side adopt giant ionic structures. Silicon oxide which is in the middle of the period forms a giant covalent structure. Oxides of other elements towards the right hand side form molecular oxide structures.
iv) The acidity of oxides of period 3 increases from left to right. Metals on the left hand side form basic oxides while non-metals on the right hand side form acidic oxides. The oxide of aluminium in the middle is amphoteric.
v) The oxides of period 3 elements do not conduct electricity. However, the metallic oxides on the lefthand side conduct electricity in molten state. The non-metallic oxides on the right hand side are molecular hence they do not conduct electricity under any circumstance.
It was used from the Bronze Age(3000 BC) and tin was used in the bronze.
That a particular concept- the Alcubierre Warp Drive- might actually be feasible.... the major hurdles and opportunities presented by warp mechanics research
Only the oxygen part of the atmosphere participates in the burning of candle wax.
When the candle is burning, the wick burns and the heat generated from burning melts the wax. The liquid wax serves as a fuel that sustains the burning of the wick.
The candle wax is a hydrocarbon. Hydrocarbon compounds are generally known to burn is oxygen to produce carbon dioxide and water.
Thus, the candle wax burns in the oxygen component of the air to produce carbon dioxide and water as by-products. All other components of air do not participate in the system.
