Valence electrons are the electrons in the outermost shell. Those are t<span>he electrons on an atom that can be gained or lost in a chemical reaction.
</span>Elements that are left on the periodic table <span> have relatively few </span>valence electrons<span>, and can form ions more easily by losing their </span>valence electrons<span> to form positively charged cations.</span>
<span>Nonmetals are further to the right on the periodic table, so they gain electrons relatively easily and lose them with difficulty. </span>
<span>An acid is a compound that produces hydrogen ions when dissolved in water. The pH of acid is less than 7 because it is rich in H+ concentration. Basic solutions have pH greater than 7 because it is rich in OH-. Neutral solutions meanwhile have pH equal to 7.</span>
A chromosome is a tightly coiled X of genetic material that has genes on it.
Hope this helps!
1L ------------ 1 kg
? ------------- 3.8 kg
3.8 x 1 / 1
= 3.8 L
The second one.
Remember, temperature is the AVERAGE kinetic energy. So, looking for highest average kinetic energy means looking for highest temperature, which is 55.
Note: the amount of the substance does not determine the average kinetic energy.
