Answer: The chemical formula for this complex is $[Cd(C_{10}H_8N_2)_2]Cl_2$ or $[Cd(bipy)_2]Cl_2$

Explanation:

2,2'-Bypridine is a bidentate chelating ligand which forms complex with many transition metals. Its chemical formula is $C_{10}H_8N_2$

Bidentate ligands are the ligands which donate two pairs of electrons to the metal atom.

This complex contains two spheres: Primary sphere and secondary sphere

Primary sphere is the sphere which satisfies the primary valency of the metal and the coordination sphere satisfies the secondary valency of the metal known as secondary sphere.

Chlorine is satisfying the primary valency of the metal and bipyridyl is satisfying the secondary valency of the metal.

The chemical formula for this complex is $[Cd(C_{10}H_8N_2)_2]Cl_2$ or $[Cd(bipy)_2]Cl_2$ and its structure is given in the image attached.

What is the mass, in grams, of 122 atoms of aluminum? Round your answer to proper significant figures.

tangare [24]

Answer:

Mass = 547.02 × 10⁻²³g

Explanation:

Given data:

Number of atoms of Al = 122 atom

Mass in gram = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

122 atom/6.022 × 10²³ atoms × 1 mol

20.26× 10⁻²³ mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 20.26× 10⁻²³ mol × 27 g/mol

Mass = 547.02 × 10⁻²³g

Calculate the gravitational force of attraction between a 26kg boy and his 5.1kg dog when they are separated by 0.19m

Pavel [41]

Answer:

Gravitational force of attraction G(f) = 2.44 x 10⁻⁷ (approx.)

Explanation:

Given:

Mass M1 = 26 kg

Mass M2 = 5.1 kg

Distance r = 0.19 m

Find:

Gravitational force of attraction G(f)

Computation:

Gravitational force of attraction G(f) = G(m1)(m2)/r²

Gravitational force of attraction G(f) = [6.67 x 10⁻¹¹](26)(5.1)/(0.19)²

Gravitational force of attraction G(f) = 8.84 x 10⁻⁹ / 0.0361

Gravitational force of attraction G(f) = 2.44 x 10⁻⁷ (approx.)

2. Why does a chemical equation need to be balanced?

arlik [135]

Answer:

Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system. The law of conservation of mass governs the balancing of a chemical equation.
