At which point does a chemical reaction reach dynamic equilibrium?
A. When no further reaction occurs in either direction of the reaction
B. When the concentrations of reactants and products are different
O C. When reactants are decreasing rapidly and products are
increasing slowly
D. When the concentrations of reactants and products stay the same
Answers
Answer:
D. When the concentrations of reactants and products stay the same
Explanation:
[tex]\bigstar[/tex] Dynamic equilibrium is when rate of forward reaction is equal to the
rate of backward reaction. The concentration of Product and Reactant
are both same, no net change. Hence Option D is correct.
When the concentrations of reactants and products stay the same at this point a chemical reaction reach dynamic equilibrium.
Hence, Option (D) is correct answer.
What is a Chemical Reaction ?A chemical reaction is a process in which chemical bonds between atoms to break and reorganize, to form other new substances.
What is Dynamic Equilibrium ?Dynamic equilibrium occurs in reversible reactions when the number of particles becomes product is equal to number of particles becomes reactant. Chemical equilibrium is dynamic in nature.
Thus from the above conclusion we can say that When the concentrations of reactants and products stay the same at this point a chemical reaction reach dynamic equilibrium.
Hence, Option (D) is correct answer.

Which of the following elements are already balanced in this equation? FeS₂ + Cl₂ → FeCl₃ + S₂ Cl₂
Answers
Fe and S are already balanced in this equation
Further explanationBalanced indicates that the number of elements in question has the same number of atoms both on the left side (the number on the reactants side) and on the right side (the number on the product side)
Even though one of the elements is said to be balanced, the chemical equation as a whole cannot be said to be balanced, because the chemical equation has several components of the constituent elements.
To balance chemical equations, a coefficient in front of the compound is usually added either in the reactants or products
Reaction
FeS₂ + Cl₂ → FeCl₃ + S₂Cl₂
From this equation, it can be shown that: the Fe and S elements are balanced because the numbers are equal both on the left and right, while the Cl elements are not yet balanced
Fe, left=1, right=1 ⇒ balanced
S, left=2, right=1 ⇒ balanced
Cl, left=2, right=5⇒ not balanced
For balanced equations:
2FeS₂ + 5Cl₂ → 2FeCl₃ + 2S₂Cl₂

Describe how the nervous system helps the boy detect the aroma coming from the pot on the stove.
Answers
Answer:
When a boy smells the aroma coming from the pot on the stove is actually detecting the chemicals coming from the air which comes from hot food that dissolves in the mucus present in the nasal cavity that carries tiny hairs made up of the nerve fibers that absorb these chemicals and excite or stimulate the olfactory receptors.
Various types of a distinct aroma or smell lead to a specific combination of the olfactory cells to make a specific smell. These combination patterns transported to the olfactory bulb along axons; a long extended neuron.
The sensory patterns or information encoding the smell of food present in the pot reaches the primary olfactory cortex in the brain, which is present on the anterior surface of the temporal lobe, and decodes accordingly.
Answer:You breath in what you smell and if it smells good or not you usely get up an see what is in the kitchen

Chemistry - Stoichiometry
Reading a Periodic TableUsing Dimensional AnalysisExplanation:
Step 1: Define
16.25 g FeCl₃ (Iron III Chloride)
RxN: 2Fe + 3Cl₂ → 2FeCl₃
Step 2: Identify Conversions
Molar Mass of Fe - 55.85 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of FeCl₃ - 55.85 + 3(35.45) = 162.2 g/mol
Step 3: Stoichiometry
[tex]16.25 \ g \ FeCl_3(\frac{1 \ mol \ FeCl_3}{162.2 \ g \ FeCl_3} )(\frac{2 \ mol \ Fe}{2 \ mol FeCl_3} )(\frac{55.85 \ g \ Fe}{1 \ mol \ Fe} )[/tex] = 5.59533 g Fe

How many grams of C are required to react with 97.1 g of Fe2O3?
Answers
Answer:
21.9 g C
Explanation:
Fe₂O₃ + 3 C ⇒ 2 Fe + 3 CO
This is your chemical equation.
To find the grams of C required, first convert grams of Fe₂O₃ to moles using the molar mass (159.69 g/mol).
(97.1 g)/(159.69 g/mol) = 0.608 mol Fe₂O₃
Then, use the mole ratio between Fe₂O₃ and C to convert moles of Fe₂O₃ to moles of C. You can find the mole ratio by looking at the chemical equation.
(0.608 mol Fe₂O₃) × (3 mol Fe₂O₃/1 mol Fe₂O₃) = 1.824 mol C
You can then convert moles of C to grams using the molar mass (12.01 g/mol).
(1.824 mol) × (12.01 g/mol) = 21.9 g

A) Mention any two properties of an ideal fuel. (b) What is meant by calorific value? (c) 2kg of a fuel produces 48,000 KJ of heat energy and complete combustion. Calculate the calorific value of the fuel.
Answers
Answer and explanation:
A) An ideal fuel must:
- easy to transport and storage.
- have a high calorific value.
B) The calorific value for a fuel is the amount of heat - measured in Joules- which is produced during the complete combustion of the fuel. It is expressed in Joules per Kg of fuel (J/kg).
C) From the data:
mass of fuel = 2 kg
heat produced = 48,000 KJ
We calculate the calorific value by dividing the heat produced by the mass of fuel, as follows:
calorific value = heat produced/mass of fuel = (48,000 KJ)/(2 kg)= 24,000 kJ/kg
Since 1 KJ= 1000 J, we can express the calorific value in J/kg as follows:
24,000 kJ/kg x 1000 J/1 kJ = 2.4 x 10⁷ J/kg

How does an atom of one element differ from the atom of another element?
-Are there other ways to change the identity of an atoms? Explain, please.
Answers
Explanation:
The atoms of one element differs from the atoms of other elements in terms of the number of protons they contain. This is often taken as the atomic number of such an atom.
The number of proton is the best indicator of the atom one is dealing with. Based on this number, elements are categorized into distinct columns and rows on the periodic table. The atomic number is the number of protons or positively charge particles in the atom.II.
It is possible to change the identity of an atom. This is only possible by altering the atomic number of the atom.
Only nuclear reactions have this capability.
When an atom undergoes nuclear reaction that involves change in number of protons, transmutation occurs and a new atom forms.
