According to ideal gas equation, 0.122 moles of nitrogen are produced by the reaction.

The ideal gas equation is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.The law was proposed by Benoit Paul Emile Clapeyron in 1834.The ideal gas law is applicable to ideal gases.The graph of ideal gas equation is a straight line passing through the origin.

Substituting the values of P=1 atmosphere, V= 278 liters,R= 8.314, T= 273 K in the above equation that is n=PV/RT=1×278/8.314×273=0.122 moles.

Thus, 0.122 moles  of nitrogen are produced by the reaction.

The mole ratio Aluminium to Aluminum Oxide is 2 : 1

Given

Reaction

2Al + Fe ----> Al2O3 +2Fe

Required

The mol ratio

Solution

If we look at the reaction above, there is an element missing from the reactant i.e oxygen, because the number of atoms and elements involved in the reaction should be the same between the reactants and products.

So the possible and balanced reactions are:

2Al(s) + Fe₂O₃ (s)  →  Al₂O₃ (s)+ 2Fe (s)

From this reaction the ratio of Al: Al₂O₃ can be determined, which is 2: 1

Answer:

blank space one- 0

blank space two- 0

Explanation:

Answer:  The mass M = 9g, so G = 9g x 9.8 m/s² = 88.2gm/s², or 88.2 newtons. Insert the tension and gravitational force you just calculated into the original equation: -F = T + G = 18N + 88.2N = 106.2N. The force is negative because the object in the pulley system is accelerating upwards.

Explanation:

Answer:

Humans, as well as monkeys, gorillas, and other primates, have a hand that can grip and grasp objects because they have an opposable thumb. The earliest primates were arboreal (they climbed trees), and so having grasping hands was an advantage in this environment.

If you asking about the neon and argon thing then I'll answer it tho!

Neon and Argon's are fully filled electron's in their 1 st shell or most likely it's outermost shell which have 8 electron's in total and it cannot take or loose any of them and it can't even share it tho to anyone and that's why  argon have a zero valency

Answer:

Due to application of heat on a saturated solution, the interparticle space increases due to increase in the kinetic energy of the particles which allows more solutes to dissolve in the solution thereby making it unsaturated.

Answer: Evaporation

Explanation:

When the heat of the sun touches the water, the water molecules heat up and move gradually faster. Over time molecules start to pop out the surface of the water individually.

And then eventually all the water is evaporated into water vapor.

Answer:

Hydrogen

Explanation:

The noble gas helium is found in the first period in the periodic table. The only element that is also in that period is hydrogen.

Now, helium has two electrons in its outermost shell. It is the first member among the noble gases.

Each hydrogen atom has only one electron. Therefore, when two hydrogen atoms are joined by a singe covalent bond to form hydrogen gas, each hydrogen atom now has two electrons thereby attaining the electronic configuration of helium, the nearest noble gas to hydrogen.

Stoichiometry

Step 1: Define

[RxN} FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl

[Given] 2.43306 g FeCl₃

Step 2: Identify Conversions

[RxN] 1 mol FeCl₃ = 3 mol NaCl

Molar Mass of Fe - 55.85 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of Na - 22.99 g/mol

Molar Mass of FeCl₃ = 55.85 + 3(35.45) = 162.2 g/mol

Molar Mass of NaCl - 22.99 + 35.45 = 58.44 g/mol

Step 3: Stoichiometry

Explanation:

In looking at molecules to determine whether they are polar or not we have to look at two things basically;

i) presence of polar bonds

ii) geometry of the molecule

Now, we know that CCI2F2 is a tetrahedral molecule, but the molecule is not symmetrical. It has four polar bonds that are not all the same hence the molecule is polar.

In an electric field, polar molecules orient themselves in such a way that  the positive ends of the molecule are being attracted to the negative plate while the negative ends of the molecules are attracted to the positive plate.

So the positive ends of CCI2F2  are oriented towards the negative plate of the field while the negative ends of CCI2F2 are oriented towards the positive ends of the field.

Answer:

37.9g of carbon 14 remains

Explanation:

The radioactive decay of an atom follows the equation:

Ln[A] = -kt + Ln[A]₀

Where [A] is amount of isotope after time t, k is decay constant and [A]₀ initial amount of the isotope.

We can find k from half-life using:

k = ln 2 / Half-Life

k = ln 2 / 5730 years

k = 1.2097x10⁻⁴ yrs⁻¹

Replacing in the equation all values:

Ln[A] = -1.2097x10⁻⁴ yrs⁻¹*2292yrs + Ln[50g]

Ln[A] = 3.635

[A] = 37.9g of carbon 14 remains
