Answer:

Yes

Explanation:

4Fe+3O2

4Fe

3O2

So therefore 6 Oxygen atoms

2Fe2

2x2

Therefore 4 Iron atoms

2O3

2x3

Therefore 6 Oxygen atoms

 Convert the following to moles.
Luda [366]
Use dimensional analysis.
\frac{60.0 grams NaOH}{1} *  \frac{1 mole NaOH}{40.0 amu NaOH} =1.5 moles

\frac{2.73 grams NH4Cl}{1} *  \frac{1 mole NH4Cl}{53.49 amu NH4Cl} = .051 moles

Now you try converting moles to grams. All you have to do is start with MOLES  (Unlike the previous examples) over 1 then multiply that ratio by the ratio of molar mass over 1 mole. Hope this helps!

What is the name for the process by which gases spontaneously move from an area of higher concentration to one of lower concentr
AysviL [449]
The process by which gasses spontaneously move from an are with higher concentration to one of lower concentration is called diffusion. This process mainly occurs in gases and liquids. The end result of diffusion is called dynamic equilibrium. It is a complete mixing of the molecules  of the gas.

The second reaction in the formation of sulfuric acid occurs slowly.
rjkz [21]

<u>Answer:</u> The correct option is NO_2(g)

<u>Explanation:</u>

A catalyst is defined as the chemical species that increases the reaction rate but does not participate in it and is left behind after the completion.

A homogeneous catalyst is one that is present in the same phase as the reactants and products.

A heterogeneous catalyst is one that is present in different phase as that of reactants and products.

For the given chemical reaction:

2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)

As all the reactants and products are in gaseous state so, the homogeneous catalyst must also be in the gaseous state only.

Hence, the correct option is NO_2(g)

How many moles of helium are needed to fill a balloon to a volume of 5.3 L at 22 ℃ and 632 mmHg?
son4ous [18]

Answer:

0.18 moles

Explanation:

Applying,

PV = nRT................... Equation 1

Where P = pressure, V = volume, n = number of moles, R = molar gas constant, T = temperature.

make n the subject of the equation

n = PV/RT............... Equation 2

Given: V = 5.3 L, T = 22 °C = (22+272) K = 295 K, P = 632 mmHg = (0.00131579×632) = 0.8316 atm,  R = 0.083 L.atm/K.mol

Substitute these values into equation 2

n = (0.8316×5.3)/(0.083×295)

n = 0.18 moles
