The sample that has the highest solubility is THE FIRST SAMPLE [TABLE SUGAR NO 1].
Solubility refers to the quantity of a solute that will dissolve in a given volume of solvent at a given temperature and pressure. The question above tells us that equal amounts of sugar and table salts were used. But looking at the table given in the question, you will see that sample 1 has the highest amount of solute that dissolve, that is 80, the rest of the samples have values that are lower than that.
The most electronegative element is fluorine. <span> And since it is the most electronegative element the electrons tend to "hang out" more toward the fluorine atom when fluorine is covalently bonded to other atoms. Hope this answers the question. Have a nice day.</span>
Answer:
4121 years
Explanation:
From;
0.693/t1/2 = 2.303/t log No/N
t1/2= half life of the carbon-14
No= count rate of the living tissue
N= count rate of the sample
t = age of the sample
0.693/5730 =2.303/t log (13.5/8.2)
1.21 * 10^-4 = 2.303/t * 0.2165
1.21 * 10^-4 = 0.4986/t
t = 0.4986/1.21 * 10^-4
t = 4121 years
Answer:
I'm not 100% sure but I believe it is the first or last
there should be three y's and one x but I can't remember the order. my gut goes with the top one
3, 9, 16 are correct! 17 should be b because buffered means that it resists change in pH
