1. Plasma
2. Bone marrow
3. Cells
4. Hemoglobin
5. Capillary
6. Ventricle
7. Heart chamber
Answer is 5.0 mol.
<em>Explanation;</em>
The balanced reaction between KMnO₄ and HI is
2KMnO₄ + 10HI + 3H₂SO₄ → 2MnSO₄ + K₂SO₄ + 5I₂ + 8H₂O
The stoichiometric ratio between HI and I₂ is 2 :1.
Hence, moles of HI needed = moles of 5I₂ produced x 2
= 2.5 mol x 2
= 5.0 mol
example calculation for a.)
N = 39 - P
N = 39 - 19
<u>N = 20</u>
<u>P = 19</u>
Answer:

Explanation:
<u>Q. 4:</u>
a) 7 ml
b) 9 ml
c) volume of rock = volume of column (with rock in it) - volume of column (without rock)
= 9-7
= 2 ml
d) density = mass ÷ volume
therefore, mass = volume × density
= 2 × 3 => 6 g
<u>Q. 5:</u>
1st has the highest density
this is because, density = mass ÷ volume
as volume is constant , density is directly proportional to mass
as image 1 has more number of molecules, it's mass will be maximum.
therefore, 1st image will have maximum density
Answer:
Aqueous layer (1 M HCI)
Explanation:
First of us I want to remind you of the cliché in chemistry that like dissolves like. In solvent extraction, a mixture is dissolved in a system consisting of two immiscible solvents. One layer is organic while the other layer is aqueous.
Polar substances partition in the aqueous layer while nonpolar substances partition in the organic layer.
Since Copper sulfate is ionic, we will find it in the aqueous layer according to the old chemistry cliche.
