Write the formula of the coordination compound pentaamminecarbonatocobalt(III) iodide. Enclose the coordination complex in squar

e brackets, even if there are no counter ions. Do not enclose a ligand in parentheses if it appears only once. Enter water as H2O. Use any abbreviation given in blue below, and enclose it in parentheses if there is more than one.

Answer:

[Co(NH3)5CO3]I3

Explanation:

The naming of coordination compounds follows certain rules specified by IUPAC. Usually, the name of the complex makes it quite easy to deduce its structure.

"Pentaamine" means that there are five NH3 ligands as shown in the structure. The ligand carbonato is CO3^2-.  It has no prefix attached to it in the IUPAC name of the complex hence there is only one carbonato ligand present(recall that the complex has a coordination number of six). I did not enclose it within parenthesis as required in the question.

Lastly the III that appeared after the metal name "cobalt" shows its oxidation state. The iodide counter ions must then be 3 in number in order to satisfy this primary valency of the metal hence the inclusion of I3 in the structure of the complex.

larisa86 [58]

Answer:

The correct option is: b. the elements in the material are well apart (in different sides) in the periodic table            

Explanation:

Ionic bond is a type of chemical bonding that is formed by the transfer of electrons from one atom to another. It is formed between atoms having large electronegativity difference.

The more electronegative atom accepts electrons and becomes a negatively charged anion. Whereas, the less electronegative atom loses electrons and becomes a positively charged cation.

<u>Simply, an ionic bond is formed when the electrons are transferred from a metal to a non-metal, which are present on different sides of the periodic table.</u>

PLEASE HELP DUE TONIGHT THANK YOU
Sav [38]

Answer:

check the attached image. hope it helps

Explanation:

a. What does mol/L mean? mol/L means Molar Concentration

b. Describe in your own words how mol/L compares to grams/liter. (similarities and differences)

<u>Similarities:</u><u> </u>mol/L and grams/liter both are units of concentration.

<u>Differences</u>:

mol/L concentration says how many moles of solute are present in 1L of solution.

grams/liter concentration says how many grams of solute are present in 1L of solution.

3. Describe at least 2 ways in the simulation to change each of the parameters:

a. Volume of solution= evaporating or adding more water

b. amount of solute=reducing the water or evaporating more water

c. Concentration of solute in solution = evaporating or adding more solute

Two 0.75 Amp loads are connected in parallel with a 2500 Milliamperehour Ni-Cd battery. Approximately how long can the battery p
nikdorinn [45]

Explanation:

It is given that two loads have 0.75 Ampere current each. And, they contain 2500 milli ampere per hour Ni-Cd battery.

As both the loads are connected in parallel. Hence, total current will be calculated as follows.

               I = I_{1} + I_{2}

                 = 0.75 A + 0.75 A

                 = 1.5 A

                 = 1.5 A \times \frac{1000 mA}{1 A}

                 = 1500 mA

Relation between time and capacity of battery is as follows.

             Capacity = Current × time (in hour)

therefore,        time = \frac{Capacity}{Current}

                                = \frac{2500 mA. h}{1500 A}

                                = 1.667 hr

Thus, we can conclude that the battery provide power to the load up to 1.667 hours.

5. Balance the following reactions using either the oxidation number method or the half-reaction
stich3 [128]

The balanced reaction equations are;

a) 4 NaClO + H2S → 4 NaCl + H2SO4

b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O

<h3>What is a balanced redox reaction?</h3>

A redox reaction is said to be balanced when the number of electrons gained is equal to the number of electrons lost.

Let us now write the balanced reaction equations one after the other. Thus;

a) 4 NaClO + H2S → 4 NaCl + H2SO4

b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O

What is thermal energy transfer?
Ray Of Light [21]

Answer:

Heat is a measure of the flow of thermal energy from one object or substance to another. ... Thermal energy typically flows from a warmer material to a cooler material. Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases.
