If they're half life, wouldn't that mean every 5730 years I would double? So 12.5 x 2= 25, 25 x 2 = 50, and 50 x 2 = 100% carbon-14. It doubled 3x so the 5730 x 3 = amount of years the volcano erupted

It erupted 17,190 years ago.
It has a half life of 5,730 years. Therefore, when it has 50% remaining, it has lived for 5,730 years. When it has 25% remaining, it has lived for 11,460 (5730+5730). When it has 12.5% remaining (25/2), then it has lived 17,190 years (11,460 + 5730).

If the ligand has a negative charge at a particular location, what would happen if you tried to put electrons from the metal nea
slega [8]

Answer:

The two would end up repelling each other very strongly and more energy would ultimately be required to keep the metal-ligand system in place

Explanation:

A complex is made up a central metal atom or ion and ligands. Ligands are lewis bases and they possess lone pairs of electrons. A complex is formed when electrons are donated from ligand species to metals.

However, if the ligand has a negative charge at a particular location and we try to put electrons from the metal near the electrons from the ligand, the two would end up repelling each other very strongly and more energy would ultimately be required to keep the metal-ligand system in place.

Sunlight is more spread out as you move away from the equator.
suter [353]

Answer:

False.

Explanation:

<u>The given statement asserts a false claim because the equator is the region that receives maximum sunlight</u>. The equator is placed right below the sun and thus, it tends to receive the maximum radiation across the year. While the poles are the coldest regions of the Earth because due to Earth's titled axis, they receive very few sun rays for a certain time of the year. Thus, <u>if we move away from the equator, we are likely to receive less radiation from the sun as the sun keeps getting farther while moving away from the equator</u>.

aivan3 [116]

Answer:

first the right answer is

Li + H2O = LiOH + H2O

then to balance it...

2 Li + 2 H2O = 2 LiOH + H2

so that we can have both side of the equation to be equal....
