I believe it is C, as helium is one of the lightest noble gases making the particles move faster.
Answer:
Metallic structure
Explanation:
They have a high melting point due to the strong forces of attraction between the positive ions (cations) and the delocalised electrons. Moreover, they conduct electricity due to the sea of delocalised electrons.
<em>[Extra: It could be an ionic compound since they also have a high melting point, however they only conduct electricity in liquid or aqeouus state.]</em>
D) life on earth was seeded by extraterrestrial aliens
Answer:
Average of the trial is: 288.50 C
Percent Error: 3.83%
Explanation:
(291 + 287 + 295 + 281) : 4 = 288.50 C
Average: 288.50 C
Percent Error: {(300 - 288.50) : 300} x 100% = 3.83 %
