Is iced tea with no ice a homogenuous or a heterogenuous mixture? ...?

1 answer:

3 0

It is a homogeneous mixture because you cannot see the individual components that make up the iced tea (such as the water, the molecules found in the tea leaves, etc.). Iced tea with ice in it is considered a heterogeneous mixture because you can distinguish the tea from the ice.

How many atoms are present in 0.529 moles of Li?

nirvana33 [79]

Answer:

<h2>3.18 × 10²³ atoms</h2>

Explanation:

The number of atoms can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 0.529 × 6.02 × 10²³

We have the final answer as

<h3>3.18 × 10²³ atoms</h3>

Hope this helps you

Two voltaic cells are to be joined so that one will run the other as an electrolytic cell. In the first cell, one half-cell has

Au/Cr cell will run as a voltaic cell and Co/Zn cell will run as an electrolytic cell.

<h3>What is an electrolytic cell?</h3>

An electrolytic cell that uses electrical energy to enable a non-spontaneous redox reaction is known as an electrolytic cell.

Certain chemicals can be electrolyzed using electrolytic cells, which are electrochemical cells.

For example, water can be electrolyzed to create gaseous oxygen and gaseous hydrogen with the use of an electrolytic cell.

The following are the three essential parts of electrolytic cells:

Cathode (which is negatively charged for electrolytic cells)

Anode (which is positively charged for electrolytic cells)

Electrolyte

The reactions for each half cell is given by

$Au^{3+}(aq) + 3e^- \rightleftharpoons Au(s)$ ; E° = 1.50 V

$Cr^{3+}(aq) + 3e^- \rightleftharpoons Cr(s)$ ; E° = –0.74 V

$Co^{2+}(aq) + 2e^- \rightleftharpoons Co(s)$ ; E° = –0.28 V

$Zn^{2+}(aq) + 2e^- \rightleftharpoons Zn(s)$ ; E° = –0.76 V

When the Au/Cr cell will run as a voltaic cell and Co/Zn cell will run as an electrolytic cell, the a difference in the voltages is produced

$E^o_{series} = E^o_{Au/Cr} - E^o_{Co/Zn}$ = 2.24 V – 0.48 V = 1.76 V

What is the volume of 7.50x10^24 molecules of NH3 at STP

Bas_tet [7]

Answer:

V NH3 = 304.334 L

Explanation:

1 mol ≡ 6.02 E23 molecules

⇒ moles NH3 = (7.50 E24 molecules)×(mol/6.022 E23 molecules)

⇒ mole NH3 = 12.454 mol

assuming ideal gas:

PV = RTn

STP:

∴ T = 25°C ≅ 298 K

∴ P = 1 atm

⇒ V NH3 = RTn/P

⇒ V NH3 = ((0.082 atm.L/K.mol)×(298 K)×(12.454 mol))/(1 atm)

⇒ V NH3 = 304.334 L

¿Por qué los gases nobles tienen tendencia a no formar compuesto si como todo elemento de la tabla periódica estos tienen electr

White raven [17]

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
