How does the picture show that the inner core spins faster than the outer core?

Based on periodic properties, choose the more metallic element from each of the following pairs.
dimulka [17.4K]

Answer:

Sr is the more metallic element

Bi is the more metallic element

O is the more metallic element

As is the more metallic element

Explanation:

One thing should be clear; metallic character increases down the group but decreases across the period.

Hence, as we move across the period, elements become less metallic. As we move down the group elements become more metallic.

This is the basis upon which decisions were made about the metallic character of each of the elements listed above.

Please help! I'm not a smart 7th grader, on this assignment you write if it's convection, radiation, or conduction, then you wri
sattari [20]
#8 would be radiation
Because of the heat it produces for the air in the home
#9 Conduction
Because it’s preventing physical heat transfer
#10 convection
Because it is stopping the air from rising
#11 Radiation
Because the heat is emitting from the stove and warms him, but not by direct contact
#12 Conduction
Because the heat transfers from the top of the stove to the cats fur.
#13 Conduction
Because the stove under it heats it through contact
#14 I think Radiation
Because the heat warms up the dish through the air in the oven
#15 Radiation
Because the heat is emitting from the fire.
#16 Conduction
Because the blanket is warming you through physical contact.

I’m not completely sure but the is the best I got. Good luck!

A sample of a substance has these characteristics: melting point of 984 K hard, brittle solid at room temperature poor conductor
ANEK [815]

The correct answer is option 4, that is, an ionic compound.  

The mentioned features belong to an ionic compound. The ionic compounds exhibit strong bonds in between their atoms, that is, an ionic bond is the strongest molecular bond, this confirms that ionic compounds exhibit a high melting point.  

The ionic compounds do not transmit current, as they do not possess free electrons, like metals, thus, they are poor conductors as solid. The ionic compounds get dissolve in water and form ions that are the charges, which can move, making them good conductors as a liquid. The composition of the ionic compound is a set of crystals that makes them brittle and hard.
