if the complex has a formula of [m(h2o)6]3 , what effect will replacing the 6 aqua ligands with 6 cl− ligands have on δ ?
Eduardwww [97]

When we replace neutral ligands with negative ligands then the value of C.Δ will decrease.

In coordination chemistry, a ligand is an ion or molecule that binds to a significant steel atom to shape coordination complicated. The bonding with the metal generally includes a formal donation of 1 or more of the ligand's electron pairs regularly through Lewis Bases.

A ligand is defined as any molecule or atom that irreversibly binds to a receiving protein molecule, otherwise known as a receptor. whilst a ligand binds to its respective receptor, the shape and/or interest of the ligand is altered to provoke several special styles of cellular responses.

3h2so4 2b(oh)3 - b2(so4)3 6h2o what is the mole ratio between water and sulfuric acid?
Nutka1998 [239]

Since there is an equal number of each element in the reactants and products of 3H2SO4 + 2B(OH)3 = B2(SO4)3 + 6H2O, the equation is balanced.

<h3>What is Sulfuric acid?</h3>
  • Sulfuric acid (H2S04) is a corrosive substance, that destroys the skin, eyes, teeth, and lungs. Severe vulnerability can result in death. Workers may be harmed from disclosure to sulfuric acid. The level of exposure depends on
  • The sulfuric acid bleaching can substitute the presently assumed oxygen and chlorine stages if the additives are allowed. This bleaching process was also practical for oxygen-bleached hardwood kraft pulp, but it was less compelling for softwood kraft pulp and oxygen-bleached softwood kraft pulp.
  • Disbanding sulfuric acid in water is an exothermic procedure. When sulfuric acid is mixed with ice this exothermic procedure causes the temperature to rise at first, but as more of the ice dissolves, the temperature falls.

Compare photons of gamma and radio radiation. which has: the longer wavelength? the greater frequency? the greater energy?
Nataly [62]
<span>Gamma radiation has a shorter wavelength, a higher frequency and higher energy than radio radiation. Wavelength is inverse to frequency and energy (i.e. higher wavelength means lower frequency and lower energy, and vice versa).</span>

Suppose you have an Avogadro's number of nitrogen atoms. How many grams does this represent? Enter your answer to one decimal pl
shusha [124]

Answer:

2.3 x 10-23 g.

Explanation:

The mass of a single atom is the mass number, 14, is the mass in grams of one mole of carbon.

One mole of Nitrogen atom is 6.022 x 1023 atoms (Avogadro's number). This can then used to convert a nitogen atom to grams by the ratio:

mass of 1 atom / 1 atom = mass of a mole of atoms / 6.022 x 10^23 atoms.

mass of 1 atom = mass of a mole of atoms / 6.022 x 1023

mass of 1 N atom = 14 / 6.022 x 10^23 N atoms

mass of 1 N atom = 2.325 x 10^-23 g

The mass of a single Nitrogen atom is 2.325 x 10-23 g.
