Answer:
Density = 2.5 g/cm³ , The metal is aluminium.
Explanation:
Density is defined as the ratio of the mass and the volume
Thus,

Given that:
Mass = 612 grams
Volume = 245 cm³
Thus, Density is:

<u>Density = 2.5 g/cm³</u>
Metals are shiny with high density.
<u><em>The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range. </em></u>
<u><em>The metal is aluminium.</em></u>
<u><em></em></u>
Honestly, its based on your preference but the best recommended one would be loam. I use loam too, and it is really good for growing the plants.

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
<u>Answer:</u> The percent yield of the compound is 30.86 %.
<u>Explanation:</u>
To calculate the percentage yield of a compound, we use the equation:

Experimental yield of compound = 25 g
Theoretical yield of compound = 81 g
Putting values in above equation, we get:

Hence, the percent yield of the compound is 30.86 %.
