Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of _______.
murzikaleks [220]

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.

Coke is an impure form of carbon that is often used in the in- dustrial production of metals from their oxides. If a sample of c
steposvetlana [31]

Answer:

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.

Explanation:

2CuO+C\rightarrow 2Cu+CO_2

1 Ton = 907185 grams

Mass of copper oxide = 1.0 Ton = 907185 grams

Moles of copper oxide =\frac{907185 g}{79.55 g/mol}=11,403.95 moles

According to reaction, 2 moles of copper oxide reacts with 1 mole of carbon.

Then 11403.95 moles of copper oxide will react with:

\frac{1}{2}\times 11403.95 mol=5,701.98 mol of carbon

Mass of 5,701.98 moles of carbon:

5,701.98 mol\times 12 g/mol=68,423.75 g

Mass of coke = x

Mass of carbon = 68,423.75 g

Percentage of carbon in coke = 95%

95\%=\frac{68,423.75 g}{x}\times 100

x=720,250.09 g=0.794 Ton

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.
