Are there particlez of matter that are smaller than atoms??? What are theses particles calling?????

1 answer:

6 0

Yes, the ones that make of the atom itself. The proton which is a positive charge which has most of the weight of the atom and is found in the nucleus. The neutron which weighs almost nothing has a neutral charge and is found in the nucleus with the protons. Lastly the electrons which have a negative charge and orbit the atom in the electron cloud around the nucleus and also weigh very little.

What else is produced during the combustion of butane, C4H10? 2C4H10 + 13O2 → + 10H2O

Neko [114]

<h3>Answer:</h3>

8CO₂

<h3>Explanation:</h3>

We are given;

Butane, C₄H₁₀

Butane is a hydrocarbon in the homologous series known as alkane.

We are required to determine the other product produced in the combustion of butane apart from water.

We know that the complete combustion of alkane yields carbon dioxide and water.
Therefore, combustion of butane will yield carbon dioxide and water.

The balanced equation for the complete combustion of butane will be;

2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O

How many grams of NH3 can be produced from 12.0g of H2?

RSB [31]

Answer:

Balanced reaction:

3 H2 (g) + N2 (g) → 2 NH3 (g)

Use stoichiometry to convert g of H2 to g of NH3. The process would be:

g H2 → mol H2 → mol NH3 → g NH3

12.0 g H2 x (1 mol H2 / 2.02 g H2) x (2 mol NH3 / 3 mol H2) x (17.03 g NH3 / 1 mol NH3) = 67.4 g NH3

Explanation: See above

Hope this helps, friend.

Devices that mix air or oxygen with flammable gasses cannot be used unless approved by

Feliz [49]

Flammable gases are gases that have the tendency to explode (burst into flames) when they come in contact with the appropriate quantities of air, oxygen, or any suitable oxidant.

Devices that mix air or oxygen with flammable gasses cannot be used unless approved by an authorized or approved personnel.

Examples of flammable gases are hydrocarbons such as Propane, Acetylene, e.t.c.

Flammable gases are dangerous to humans and the environment and if they are not handled properly, can cause severe damages and even death.

During the preparation and usage of flammable gases, safety precautions should be properly enforced such as the wearing of appropriate safety gear and goggles.

Devices that mix air or oxygen with flammable gases cannot be used unless approved by an authorized or approved personnel.

Using the thermodynamic information in the ALEKS Data tab, calculate the standard reaction entropy of the following chemical rea

Lapatulllka [165]

Answer:

-122 J/K

Explanation:

Let's consider the following balanced reaction.

N₂(g) + 2 O₂(g) ⇒ 2 NO₂(g)

We can calculate the standard reaction entropy (ΔS°) using the following expression.

ΔS° = Σ ηp × Sf°p - Σ ηr × Sf°r

where,

η: stoichiometric coefficients of products and reactants

Sf°r: entropies of formation of products and reactants

ΔS° = 2 mol × 240.06 J/K.mol - 1 mol × 191.61 J/K.mol - 2 mol × 205.14 J/K.mol

ΔS° = -121.77 J/K ≈ -122 J/K
