B .combustion because HOH and CO2 are the products of complete combustion
It can fit two more electrons within its valence shell to follow the octet rule. It will have a -2 charge to gain those two electrons to fill its octet.
The noble gas notation of an element includes a noble gas as a condensed way to describe the electronic configuration of an element. IN this case, the nearest noble gas is xenon with an atomic number of 54. Hg's atomic number is 80 so we need 26 more. In this case, after [Xe], the configuration starts with 6s². Hence to complete the configuration the answer is [Xe] 6s2 4f14 5d10
2. I believe it would be two but then again this is an incomplete answer so it is not two. It's probably going to be 3. Or 1. Because I took this test before a while back and I'm almost a 100% sure it's 1 or 3. Hope this helps slightly!
Answer: The density of the object is 1.10 g/ml
Explanation:
To calculate the mass of water, we use the equation:
Density of object = ?
Mass of object = 26.5 g
Volume of object = volume of water displaced = 24.1 ml
Putting values in above equation, we get:
Thus density of the object is 1.10 g/ml
