Answer:
Explanation:
.65 M H₂SO₄
H₂SO₄ ⇄ 2H⁺ + SO₄⁻²
C(1-x) 2xC xC
(2xC)². xC /C( 1- x ) = 1.1 x 10⁻²
4 x³C² = 1.1 x 10⁻²
4 . x³ .65² = 1.1 x 10⁻²
x³ = .0065 = 6.5 x 10⁻³
x = 1.867 x 10⁻¹
H⁺ ion concentration =
2xC = 2 x 1.867 x 10⁻¹ x .65
= .2427
pH = - log ( .2427 )
= 0 .615 .
It happens with starch granules!
Answer:
H₂Lv
Explanation:
Lv is at group 6 on the periodic table, so it has 6 valence electrons, likely oxygen. Thus, to be stable, it needs to gain 2 electrons. Hydrogen has 1 electron in its valence shell, so H₂ can share 2 electrons with Lv, and because of that, the product would be:
H₂Lv.
Psoas major muscles, kidneys, inferior ribs, and lumbar transverse processes are demonstrated on AP abdominal projections.
<h3>What are AP abdominal projections?</h3>
The anteroposterior (AP) radiograph the patient in a supine position is the basis of the majority of plain-film examinations of the abdomen.
However, an upright-position film could also be helpful in patients with suspected bowel obstruction, also as to assess the air-fluid levels in the distended bowel.
This information also can be obtained on a film of the abdomen taken with the patient in the lateral decubitus position.
An AP supine projection is usually called a flat plate or KUB (because it includes the kidneys, ureter, and bladder)
