Answer:
The answer to your question is: % error = 0.4
Explanation:
Data
real value = 22.48%
estimated value = 22.57 %
Formula
% error = |real value - estimated value|/real value x 100
%error = |22.48 - 22.57|/22.48 x 100
% error = |-0.09|/22.48 x 100
%error = 0.09/22.48 x 100
% error = 0.004 x 100
% error = 0.4
The anion<span> is also </span>larger than<span> the </span>atom<span> because of </span>electron-electron repulsion<span>. As more </span>electrons are<span> added to the </span>outer shell<span>, and even to </span>higher<span> principle energy levels, the </span>repulsion<span> bewteen the negatively charged particles grows, pushing the </span>shells<span> farther from the nucleus.</span>
The new volume is 1.9 ml
<u><em> calculation</em></u>
The new volume is calculated using the combined gas equation
that is P1V1/T1 = P2V2/T2 where
P1= 1.0 atm
V1= 21 ml
T1 = 10.0 c into kelvin = 10 + 273 = 283 k
P2 = 15 atm
V2=? Ml
T2 = 120 c into kelvin = 120 +273 = 393 K
make V2 the subject of the formula by multiplying both side by T2/P2
V2=T2P1v1 / P2T1
V2=[(393 k x 1.0 atm x 21 ml) / (15 atm x 283 K)] = 1.9 Ml
