Answer:
lets set the ratio -A/HA as R:
pH = pKa + log(R,10) => pKa + log10(R)
pH = 5.5
pKa = 4.76
R => 10^(pH - 4.76)
10^(pH - 4.76) => 5.4954
Given R (-A/HA) a number bigger than 1, then the concentration of -A is bigger than HA

Answer:
The liver, pancreas, and gallbladder are the solid organs of the digestive system. The small intestine has three parts. The first part is called the duodenum.
Explanation:
<span>109.5°.
VESPR helps predict the bond angles with the electrons being the most out. By looking that the structure of the molecule, one Si and four H, the Si atom can be seen as the center and the four H atoms can be seen around it. Now think about how the H atoms would be placed, ideally they would be placed the farthest distance from each other equidistant. So in this case it would be 109.5°.</span>
I believe the correct answer is option A. Paré.
Or otherwise known as Ambroise Paré. He was considered one of the "fathers of surgery" for modern forensic pathology. And was known to be a pioneer in surgical techniques on the battlefield using medicine, mostly in the treatment/healing of wounds.
Hope I could help! :)
Answer:
A. Felsic igneous rocks are less dense than mafic igneous rock
Explanation:
"Felsic rocks are composed of larger quantities of silicates and therefore are less dense. Felsic magma is less dense and more viscous than mafic magma." - study.com
