Answer: A COMPLEX ION contains (a central metal ion bound to one or more ligands).

Explanation: A complex ion is defined as an ion that is formed between a central metal ion and one or more surrounding ligands, molecules or ions that contain at least one lone pair of electrons. The formation of a complex ion from a metal ion and a ligand is based on Lewis acid - base reaction. The positively charged metal ion( example Cu2+) acts as a Lewis acid, and the ligand, with one or more lone pairs of electrons (example NH3), acts as a Lewis base.

An example of a complex ion is copper ammine ion,{[Cu(NH3)6]2+}.

Answer:

A complex ion contains a central metal ion bound to one or more ligands

Explanation:

A complex ion is consists of a central atom or ion, that is usually metallic, called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.

An example of a complex ion is

[Co(NH3)6]3+

Please go through the attached file for a proper representation of the complex ion.

Calculate the mass of H2OH2O produced by metabolism of 2.4 kgkg of fat, assuming the fat consists entirely of tristearin (C57H11
otez555 [7]

Answer:

2,669.58 grams of water will be produced by metabolism of 2.4 kilogram of fat.

Explanation:

2C_{57}H_{110}O_6+163O_2\rightarrow 114CO_2+110H_2O

Mass of fat = 2.4 kg = 2.4 × 1000 g = 2400 g

1 kg = 1000 g

Molar mass of fat = M

M = 57 × 12 g/mol + 110 × 1 g/mol+ 6 × 16 g/mol = 890 g/mol[/tex]

Moles of fat = \frac{2400 g}{890 g/mol}=2.6966 mol

According to reaction , 2 moles of fat gives 110 moles of water. Then 2.6966 moles of fat will give  ;

\frac{110}{2}\times 2.6966 mol=148.31 mol of water

Mass of 148.31 moles of water ;

148.31 mol × 18 g/mol = 2,669.58 g

2,669.58 grams of water will be produced by metabolism of 2.4 kilogram of fat.
