Explanation:

The mass of ammonia that would be produced is 312.5 g

First, we will write a balanced chemical equation for the reaction

The balanced chemical equation for the reaction is

3H₂(g) + N₂(g) → 2NH₃(g)

This means

3 moles of hydrogen gas reacts with 1 mole of nitrogen gas to produce 2 moles of ammonia.

First, we will determine the number of moles of each reactant present

For Hydrogen (H₂)

Mass = 83.6 g

Molar mass = 2.016 g/mol

Using the formula

[tex]Number\ of\ moles = \frac{Mass}{Molar\ mass}[/tex]

Number of moles of H₂ present = [tex]\frac{83.6}{2.016}[/tex]

∴ Number of moles of H₂ present = 41.468254 moles

For Nitrogen (N₂)

Mass = 257 grams

Molar mass = 28.0134 g/mol

∴ Number of moles of N₂ present = [tex]\frac{257}{28.0134}[/tex]

Number of moles of N₂ present = 9.174181 moles

Since,

3 moles of hydrogen gas reacts with 1 mole of nitrogen gas to produce 2 moles of ammonia

Then,

27.522543 moles of hydrogen gas will react with the 9.174181 moles of nitrogen gas to produce 18.348362 moles of ammonia

∴ 18.348362 moles of ammonia will be produced during the reaction

Now, for the mass of ammonia that would be produced

From the formula

Mass = Number of moles × Molar mass

Molar mass of ammonia = 17.031 g/mol

Mass of ammonia that would be produced = 18.348362 × 17.031

Mass of ammonia that would be produced = 312.49095 g

Mass of ammonia that would be produced ≅ 312.5 g

Hence, the mass of ammonia that would be produced is 312.5 g

Answer:

A push or pull is referred to as a force. Forces can cause objects to move, slow, stop, or change the direction in which they travel. The force of gravity, for example, pulls all objects toward the Earth's center. Every time two things interact, a force is exerted on each of them. When this happens, the two items no longer feel the force after the interaction ends.

Explanation:

Force is that external physical cause which changes or tends to change:

Answer:

0.690 liters is the volume of hydrogen gas produced if 2.00 grams of zinc is used with an excess of hydrochloric acid.

Explanation:

Zn(s)+2HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)

Mole so zinc = \frac{2.00}{65 g/mol}=0.03077 mol65g/mol2.00=0.03077mol

According to reaction, 1 mole of zinc gives 1 mole of hydrogen gas.

Then 0.03077  mole of zinc will give :

\frac{1}{1}\times 0.03077 mol=0.03077 mol11×0.03077mol=0.03077mol of hydrogen gas

Pressure of hydrogen gas ,P= 1 atm

Temperature  of of hydrogen gas ,T= 273.15 K

Volume of hydrogen gas = V = ?

Moles of hydrogen gas = 0.03077 mol

PV = nRT (Ideal gas equation )

V=\frac{nRT}{P}=\frac{0.03077 mol\times 0.0821 atm L/mol K\times 273.15 K}{1 atm}V=PnRT=1atm0.03077mol×0.0821atmL/molK×273.15K

V = 0.690 L

Explanation:

Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons. Sodium atoms have 11 electrons. Two of these are in the lowest energy level, eight are in the second energy level and then one electron is in the third energy level.

Any atom is most stable when it’s outermost energy level contains eight electrons.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer:

Atomic mass of Sodium is 22.9897 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

Answer:

When 6.38 moles of O2 and 9.15 moles of Al react, the ratio of aluminum to oxygen is 9.15/6.38 = 1.434. This shows that all of the oxygen is consumed before the aluminum and when the reaction ends the reactant aluminum is left. The number of moles of Al2O3 formed is approximately 4.25 moles.

The physical quantity that is not used when determining the stoichiometry in this experiment is temperature.

Stoichiometry offers a way in which we can calculate the amount of reactants and products using mass - mole relationship. The mass of reactants, number of moles of reactant, mass of product and mass of precipitate can all be used to determine the stoichiometry.

However, the temperature of a reaction is not used to determine the stoichiometry of the reaction.

Oxygen Reacts with Iron to Form Rust is the Correct Answer

Answer:

In Iron (II) oxide, ratio is 1:1

In iron (III) oxide, ratio is 4:2

[tex].[/tex]

In Iron (II) oxide, ratio is 1:1

Iron oxides are very important components in most soils as they have major influence on chemical, physical, and microbial properties of soils. Because of their nanoparticulate size (usually 5-200 nm), iron oxides possess large specific surface area.

Generally, iron oxides are prevalent, widely used as they are inexpensive, and play an imperative role in many biological and geological processes. They are also extensively used by humans, eg, as iron ores in thermite, catalysts, durable pigments.

When iron is exposed to moisture or oxygen, oxidation occurs. During this chemical reaction, iron is converted into iron oxide. The iron oxide typically has a reddish, flaky appearance that becomes progressively worse over time.

Answer:

Anything not on the periodic table is an element non example! ... So, for a substance to be an element, all of its atoms must have the same number of protons. Examples of elements include hydrogen, lithium, nickel, and radium.

Explanation:

Non-examples of an atom refer to entities that are not considered atoms.

Molecules consist of two or more atoms chemically bonded together. They are not considered individual atoms because they contain multiple atoms connected by chemical bonds.

Ions are electrically charged particles formed when atoms gain or lose electrons. They can be positively charged (cations) or negatively charged (anions).

Subatomic particles are the constituents of atoms. They include protons, neutrons, and electrons.

Compounds are substances composed of two or more different elements chemically combined.
