Answer : Option D) far left.

Explanation : If an unknown element displays many extremely strong metallic properties, where is it most likely to be located on the far left of the modern periodic table.

In the modern periodic table, the metallic character of the elements decreases across the periods in the periodic table from left to right. This occurs because the elemental atoms more readily accept electrons to fill their valence shell than losing them to remove the unfilled shell. Also, the metallic character increases down the groups in the periodic table. So, it is clear that the elements found on the far left are having high metallic properties in them.

Why is the base of an energy pyramid wider than the top
Zepler [3.9K]

It is due to a lack of providable energy to the next trophic level of the energy pyramid. Primary consumers only obtain around 10% of energy that producers have, and the energy depletes as you move further and further up the food chain, until you reach the tertiary consumers which have the least amount of energy at their disposal, meaning there are less of them than other organisms further down the energy pyramid.

Answer:

35.578g or 36g if you round

Explanation:

Q=mc ∆∅ where ∅ is temperature difference
