Answer:
Explanation:
Mass of one tablet = 20 mg
Mass of two tablets = 
Percent that is soluble in water = 40%
Mass of tablet that is soluble in water = 
So, mass of solute is 
Density of water = 1 kg/L
Volume of water = 1 L
So, mass of 1 L of water is 
PPM is given by
Hence, the concentration of iodine in the treated water .
Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of <u>extracellular </u><u>fluid</u>
- Extracellular fluid called cerebrospinal fluid is present throughout the CNS
- It acts as a protective layer for CNS ftom injury and shock
- Cerebrospinal fluid is clear, colorless fluid produced by the choroid plexus.
- It surrounds the brain and spinal cord.
Synovial fluid is a viscous solution found in cavities of synovial joints. The principal role of synovial fluid is to reduce friction between articular cartilages of synovial joints during movement.
- Synovial fluid is a small component of transcellular fluid component of extracellular fluid.

Answer:
2. Option B.
Explanation:
H₂SO₄ + Ba(OH)₂ → BaSO₄ + 2H₂O
You can count 2H in sulfuric acid and 2 H in the barium hyrdoxide, so the coefficient for water must be 2.
You will have 4 H on both sides of the reaction.
Try with the dissociations of each reactant
Sulfuric acid ⇒ H₂SO₄ → 2H⁺ + SO₄⁻²
Barium hydroxide ⇒ Ba(OH)₂ → Ba²⁺ + 2OH⁻
Sulfate anion bonds to barium cation to produce the salt, therefore the 2 protons will bond the 2 hydroxide in order to produce, 2 moles of H₂O
2H⁺ + 2OH⁻ → 2H₂O
Answer: 10.99
Explanation: because you take the Cao 13.9 and take CO2 which is 10.99 and it makes 24.8 . Which is CaCO3.
C,
takes dead things, makes them into other things
