how are sex cells different from body cells
Answer:
Sex cells are different in body cells because the sex cells are eggs while body cells are formed.
Which of the following elements are already balanced in this equation? FeS₂ + Cl₂ → FeCl₃ + S₂ Cl₂
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
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
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.

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.

What is the molarity of a solution if 5 moles of solute are dissolved in 8 L of solvent.
Answer:
0.625mol/L
Explanation:
Given parameters:
Number of moles of solute = 5moles
Volume of solvent = 8L
Unknown:
Molarity = ?
Solution:
Molarity is the number of moles of solute per unit volume of solution. It is mathematically expressed as
Molarity = [tex]\frac{number of moles }{Volume}[/tex]
Molarity = [tex]\frac{5}{8}[/tex] = 0.625mol/L

Describe how the nervous system helps the boy detect the aroma coming from the pot on the stove.
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

in the nucleus with electrons
in orbit around the nucleus
both in orbit and in the nucleus
Answer:
Neutrons are located in the nucleus with protons.
Explanation:
Neutrons are located in the nexus of a snippet along with protons. The nexus is the mediate portion of a snippet that contains the utmost of its body.
Protons convey a good count, while neutrons are neutral and don't convey an electric count. Electrons, on the different side, are located in route around the nexus, enwrapping snap situations or electron coverings.
Neutrons are subatomic patches that are one of the immediate ingredients of infinitesimal capitals. They're generally imported by the logo "n or no". Neutrons don't hold any net electric count companies with them.

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.
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.
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.
Which is the best example of the law of conservation of energy?
A basketball stops bouncing because its energy disappears.
A rolling skateboard slows down because some of its kinetic energy changes to heat.
A falling book hits the ground and all of its energy is destroyed.
A toy car gains speed as it moves down a ramp because the ramp creates energy.
Answer:
The answer is B. A rolling skateboard slows down because some of its kinetic energy changes to heat.

The law of conservation says energy cant be created or destroyed .Which basically eliminates all of them except b. It can only be transferred
Answer:
b
Explanation:
How many grams of C are required to react with 97.1 g of Fe2O3?
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
Which of the following is not a correct formula unit for a salt made from main group elements?
Ca0
AIFA
Al2O3
Ca3N2
Answer:
The correct option is AlFA
Explanation:
There is no element in the periodic table with the symbol of A. Thus, the compound AlFA is wrong and cannot be a salt made from main group elements. CaO is calcium oxide, Al₂O₃ is aluminium oxide and Ca₃N₂ is calcium nitride - all are evidently made from elements from the main groups of the periodic table (except the AlFA)
