In the Eqn: [3 Fe + 2 O2 → Fe3O4], How many grams of Fe will be needed to react with 6.85 mol O2 ?

Answers

Answer:

575g

Explanation:

Mole ratio Fe : O2 = 3:2

so moles of Fe = 1.5 x 6.85 = 10.275 moles

mass=moles x Ar

Ar Fe= 56

mass = 10.275 x 56=575g

why can molar mass be used as a conversion factor

Answers

From the relative atomic mass of each element, it is possible to determine each element's molar mass by multiplying the molar mass constant (1 g/mol) by the atomic weight of that particular element. The molar mass value can be used as a conversion factor to facilitate mass-to-mole and mole-to-mass conversions.

Answer:

A substances molar mass is determined by increasing its relative nuclear mass by the molar mass constanttt (1 g/mol). So the molar mass consistent can be utilized to change mass over to moles. So by duplicating a given mass by the molar mass, the measure of moles of the substance can be determined.

Explanation:

From the general nuclear mass of every component, it is feasible to decide every component's molar mass by duplicating the molar mass steady (1 g/mol) by the nuclear load of that specific element.The molar mass worth can be utilized as a change factor to work with mass-to-mole and mole-to-mass transformations.

Why is there a bond between the ions in potassium chloride

Answers

Answer:

Explanation:

When the two atoms are in contact, potassium transfers its outer electron to chlorine which readily accepts it, resulting in both atoms achieving a state of eight outermost electrons. With this electron transfer, the ionic bond in KCl is formed.

Hope this helped!!!

Potassium has just one valence electron and Chlorine has 7 electrons, Chlorine needs just one atom to complete its octet which is provided by Potassium atom for formation of Potassium Chloride (KCl).

What is Chemical Bonding?

Chemical bonding is the formation of chemical bonds present between two or more atoms or molecules which give rise to new compound. Bond is formed from electrostatic force present between oppositely charged ions like in ionic bonds or by sharing of electrons like in covalent bonds.

There are two types of Chemical Bonding:

1. Ionic Bonding

It is formed between opposite charged particles like Anion (negatively charged) and Cation (Positively charged) by the strong force of attraction.

For example, KCl formed by the ionic bond formation present between Potassium and Chlorine

2.Chemical Bonding

It is formed between two atoms for completing its octet by sharing of electrons.

For example, [tex]H_2[/tex] formed by sharing the electrons to complete its electronic configuration.

Thus, Potassium has just one valence electron and Chlorine has 7 electrons, Chlorine needs just one atom to complete its octet which is provided by Potassium atom for formation of Potassium Chloride (KCl).

2.a. 3.26 g of iron powder are added to 80.0 cm3 of 0.200 mol dm-3 copper(II)
sulfate solution. The following reaction occurs: Fe (s) + CuSO4 (aq) → FeSO4 (aq)
+ Cu (s)Determine the limiting reactant showing your working. *
Your answer

Answers

Answer:

The limiting reactant is CuSO₄.

Explanation:

The reaction is:

Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s)      (1)

To find the limiting reactant we need to find the number of moles of the reactants.

[tex] \eta_{Fe} = \frac{m}{A_{r}} [/tex]

Where:

m: is the mass of iron = 3.26 g  

[tex]A_{r}[/tex]: is the standard atomic weight of iron = 55.845 g/mol

[tex]\eta_{Fe} = \frac{3.26 g}{55.845 g/mol} = 0.058 moles [/tex]

[tex] \eta_{CuSO_{4}} = M*V [/tex]                

Where:

M: is the concentration of the CuSO₄ = 0.200 mol/dm⁻³

V: is the volume of the solution = 80.0 cm³

First, we need to convert the units of the volume to dm³ knowing that 1 dm = 10 cm and 1 L= 1 dm³.

[tex] V = 80.0 cm^{3}*\frac{1 dm^{3}}{(10 cm)^{3}} = 0.080 dm^{3} [/tex]

Now, the number of CuSO₄ moles is:

[tex] \eta_{CuSO_{4}} = M*V = 0.200 mol/dm^{3}*0.080 dm^{3} = 0.016 moles [/tex]            

So, to determine the limiting reactant we need to use the molar ratio from equation (1), Fe:CuSO₄ = 1:1

[tex]\eta_{Fe} = \frac{1 mol Fe}{1 mol CuSO_{4}}*0.016 moles \: CuSO_{4} = 0.016 moles[/tex]

Since we need 0.016 moles of Fe to react with 0.016 moles of CuSO₄ and initially we have 0.058 moles of Fe, then the limiting reactant is CuSO₄.  

Therefore, the limiting reactant is CuSO₄.  

I hope it helps you!

The limiting reactant would be CuSO4

Looking at the equation of the reaction:

Fe (s) + CuSO4 (aq) → FeSO4 (aq) + Cu (s)

The mole ratio of Fe to CuSO4 is 1:1. Thus, every 1 mole of Fe will require 1 mole of CuSO4 for reaction.

Recall that: mole = mass/molar mass

Also: mole = molarity x volume

mole of Fe = 3.26/55.8

                    = 0.058 moles

mole of CuSO4 = 0.200 x 80/1000

                            = 0.016

The mole of Fe in the reaction is more than the mole of CuSO4. Thus, CuSO4 is the limiting reactant of the reaction. Fe is in excess.

Calculate the work for the expansion of CO2 from 1.0 to 6.5 litres against pressure of 1.0 atm at constant temperature

Answers

Answer:

557.3J is the work of expansion of the CO2 gas

Explanation:

The work of expansion of a gas under constant temperature and pressure (Isobaric pressure) is:

W = P*ΔV

Where W is work

P is pressure = 1.0atm

ΔV = Final volume - Initial Volume = 6.5L - 1.0L = 5.5L

Replacing:

W = 1.0atm*5.5L

W = 5.5atmL

In Joules (1atmL = 101.325J):

5.5atmL * (101.325J / 1atmL) =

What is geological evolution?

Geological evolution is the process of gradual change and events in antiquity that include the steps to create the Earth.

At first, there was extreme volcanism, later the planet cooled to create the crust. Also, condensed water vapor formed the oceans and seas.

The geological history of Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy).

Geological evolution studies the shape of the globe, how it formed, and the relationships of the different eras and the matter that changed during them.

If 186.0 liters of gaseous O_{2} at 1.09 atm and 577.0 ºC are required for the model rocket to climb 1000 feet, how many grams of solid KClO_{3} must be in the rocket engine?

Answers

Answer:

The right answer is "236.53 g".

Explanation:

The given values are:

P = 1.09 atm

V = 186 liters

The reaction will be:

⇒  [tex]KClO_3 (s)\rightarrow 2Kcl(s)+3O_2(g)[/tex]

The moles of O₂ will be:

=  [tex]\frac{PV}{RT}[/tex]

On substituting the values, we get

=  [tex]\frac{1.09\times 186}{0.0821\times 850}[/tex]

=  [tex]\frac{202.47}{69.785}[/tex]

=  [tex]2.90 \ moles[/tex]

Now,

1 mole O₂ is produced from

= [tex]\frac{2}{3} \ mol \ KClO_3[/tex]

then,

2.90 mole O₂ is produced from 2 mol KClO₃

= [tex]\frac{2}{3}\times 2.90[/tex]

= [tex]1.93 \ mol \ KClO_3[/tex]

hence,

The number of grans of solid in the engine will be:

= [tex]1.93\times 122.55[/tex]

= [tex]236.53 \ g[/tex]
