Answer:

Potassium dicarbonatedifluoroplatinate (II)

Explanation:

Hello,

Based on the IUPAC rules, the given compound is a complex called potassium dicarbonatodifluoroplatinate (II) as long as the carbonate ion is present twice as a monodentate ligand therefore it is preceded by a "di" prefix. In addition, two fluorines are also present with the "di" prefix as well as a platinum which complete the anionic section including +2 as the platinum oxidation state.

Best regards.

The IUPAC name of compound is Potassium dicarbonatodifluoroplatinate (II)

*Note, since carbonate ion is acting as monodentate ligand, prefix of 'di' is used. In case, if it had been a bidentate ligand prefix 'bis' would have been used.

yawa3891 [41]

Explanation: Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control. The basic unit is the muscle fiber with many nuclei. These muscle fibers are striated (having transverse streaks) and each acts independently of neighboring muscle fibers.

balandron [24]

The value of Kc for the equilibrium is 0.150 mole² / litre ²

<u>Explanation:</u>

<u>Given:</u>

An equilibrium mixture in an 1.00 L vessel contains 5.30 moles of  

Mg(OH )₂  0.800 moles of Mg²⁺ and 0.0010 moles OH₋  

We have to find the value of Kc

  • Step 1: Find  the equilibrium Concentration.
  • Step 2: Substitute the values in the equation.
  • Step 3: Find the value of Kc.
  • I have attached the document for the detailed explanation

The volume of a gas is 550 mL at 960 mm Hg and 200.0 C. What volume
Masja [62]

Answer:

The volume will be 568.89 mL.

Explanation:

Boyle's law says that "The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"

Boyle's law is expressed mathematically as:

Pressure * Volume = constant

or P * V = k

Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. That is, the pressure of the gas is directly proportional to its temperature. Gay-Lussac's law can be expressed mathematically as follows:

\frac{P}{T}=k

Where P = pressure, T = temperature, K = Constant

Finally, Charles's law indicates that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

\frac{V}{T}=k

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

\frac{P*V}{T} =k

Studying an initial state 1 and a final state 2, it is fulfilled:

\frac{P1*V1}{T1} =\frac{P2*V2}{T2}

In this case:

  • P1= 960 mmHg
  • V1= 550 mL
  • T1= 200 C= 473 K (being 0 C=273 K)
  • P2= 830 mmHg
  • V2= ?
  • T2= 150 C= 423 K

Replacing:

\frac{960 mmHg*550 mL}{473K} =\frac{830 mmHg*V2}{423 K}

Solving:

V2=\frac{423 K}{830 mmHg} *\frac{960 mmHg*550 mL}{473K}

V2= 568.9 mL

<u><em>The volume will be 568.89 mL.</em></u>

What is a polyatomic ion? Consulting p.117 in text, list the formulas and names of at least 10 polyatomic ions. When writing the
aleksley [76]

Answer:

The answer to your question is below

Explanation:

Polyatomic ions are ions composed for more than 1 atom. There are polyanions and polycations.

Polyanions have a negative charge and polycations have a positive charge.

Examples

                      Polyanions                             Polycations

  acetate           CH₃COO⁻        ammonium      NH₄⁺¹                                    

  bromate          BrO₃⁻

  chlorate           ClO₃⁻

  hydroxide        OH⁻

  nitrate              NO₃⁻

  nitrite               NO₂⁻

  sulfate             SO₄⁻²

  phosphate      PO₄⁻³

  permanganate  MnO₄⁻

We write parentheses before or after a polyatomic ion to emphasize that the oxidation number of the atom which interacts with it affects all the atoms that form part of the polyatomic ion.
