Rate of consumption of N₂ = - 1.25 x 10⁻⁴
Further explanationThe reaction rate (v) shows the change in the concentration per unit time.
[tex]\tt rate=\dfrac{concentration(M)}{time(s)}[/tex]
The rate reaction for Haber Bosch :
N₂(g)+3H₂(g)⇒2NH₃(g)
From equation, mol ratio N₂ : NH₃ = 1 : 2, so
the rate of formation of ammonia = 2 x the rate of consumption of nitrogen.
Given
the rate of formation of ammonia gas : 2.5x10⁻⁴ M/s
the rate of consumption of nitrogen :
[tex]\tt \dfrac{2.5\times 10^{-4}}{2}=1.25\times 10^{-4}[/tex]
The sign negative for consumption : -1.25 x 10⁻⁴ M/s
or we can use another way:
Rate of formation of NH₃ = reaction rate x coefficient of NH₃
2.5 x 10⁻⁴ = reaction rate x 2
reaction rate = 1.25 x 10⁻⁴
Rate of consumption of N₂ = reaction rate x coefficient of N₂
Rate of consumption of N₂ = 1.25 x 10⁻⁴ x 1
Rate of consumption of N₂ = 1.25 x 10⁻⁴

A group of tourists were on an outing when they noticed that precipitation began to fall. The air temperature was 32 degree Fahrenheit. What type of precipitation did they most likely see?
Answer:
The correct answer is - rain.
Explanation:
At 32 degrees c or zero degrees Celsius, droplets of water in the atmosphere do not freeze as it is not the temperature at which water freezes but it is the temperature at which ice melts.
At this temperature the water changes its state, below 32 degrees Fahrenheit the water freezes but in the atmosphere, it not freezes necessarily and remains in the liquid state and called super-cooled liquid or water. Above this temperature, water in liquid state.
Thus, the precipitation is in the form of rain.

Why does an ionic bond transfer electrons instead of sharing?
When there is a whole transfer of valence electron between the atoms is called an ionic bond. In this type of bond construction, the atoms get contrarily charged.
The ionic bonds are formed due to electronegativity. According to Pauling, the capability of an atom to draw electrons towards itself is called electronegativity.
When there is a huge contrast in electronegativity between the atoms, the electrons are completely transferred between the atoms.
The atom that relinquishes an electron are called a cation and is positive whereas the atom that acquires an electron are called anions and are negatively charged.
Therefore, due to electronegativity, ionic bonds are formed.

1. Which pair of atoms will share electrons when a bond is formed between them? Explain why.
A. K and Cl B. Li and I C. Br and Cl D. Ba and I
Answer:
C. Br and Cl
Explanation:
When Br and Cl combines they share electrons between them to form a type of bond called covalent bond.
The sharing of electrons between two atomic species is covalent bond. It usually occurs between two atoms with a low electronegativity difference among them. Br and Cl have low electronegativity difference. Also, the bond forms between non-metalsOnly Br and Cl pair are the non-metals from the given choices.Taking into account the definition of ionic and covalent bonds, the pair of atoms Br and Cl will share electrons when a bond is formed between them.
Ionic bondAn ionic bond is a type of chemical bond that occurs when one atom gives up an electron to the other, in order for both to achieve electronic stability.
This union normally occurs between metal and nonmetal elements with different electronegativity, which means that the elements have different capacity to attract electrons.
In other words, an ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.
Covalent bondOn the other side, the covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule.
Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas. The shared electron pair is common to the two atoms and holds them together.
This caseIn this case, considering that K, Li and Ba are metallic atoms and Cl, I and Br are non-metallic atoms, the pair of atoms Br and Cl will share electrons when a bond is formed between them.

the diagram shows a race car traveling around the racetrack at a constant speed of 150km/hr. at which point on the track is the car accelerating
Answer:
B.
Explanation:
Velocity: the speed of something given direction
Acceleration: increase or decrease of velocity over time
B is the answer because it is the only point on the image that has to slow down and change direction. To turn, a vehicle must slow down so it doesn't skid. Hope this helps!
A race car traveling around the racetrack at a constant speed of 150km/hr at B point on the track is the car accelerating.
What is acceleration ?Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities, accelerations. The direction of the net force applied on the item determines the object's acceleration.
An item has positive acceleration if it is accelerating and travelling in the right direction. Positive acceleration was demonstrated in the first case by the fast automobile.
The acceleration is in the same direction as the car's motion since it is moving ahead and speeding up.
The equation a = v/t denotes acceleration ( a ), which is the change in velocity ( v ) over the change in time ( t ). This enables you to calculate the change in velocity in meters per second squared ( m/s² ).

Explanation:
consider this equation S + 3O₂ → 3O₃ Is this equation balanced? why or why not?
Answer:
This equation is not balanced because you don't have the same amount of each element on each side of the chemical reaction. The balanced equation is:
2 S + 3 ⇒ 2
The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.
Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.
The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.
By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.
Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:
Left side: 1 sulfur S and 6 oxygen O (coefficient 3 multiplied by sub-index 2)
Right side: 1 sulfur S and 3 oxygen O (subindice value)
As you can see, you have the same amount of sulfur on both sides of the equation but the amount of oxygen is different. This indicates that the chemical equation is not balanced. To balance it, as the amount of sulfur is the same, the amount of oxygen must be balanced, which is different on each side of the reaction.
A simple way is to balance the equation is to multiply the product by 2, that is, add a coefficient 2 in front of the SO3 molecule, the reaction being as follows:
S + 3 ⇒ 2
Now the amount of elements on each side of the equation is:
Left side: 1 sulfur S and 6 oxygen O (coefficient 3 multiplied by subindice 2)
Right side: 2 sulfur S and 6 oxygen O (coefficient 2 multiplied by subindice 3)
The oxygen is now balanced, but the amount of sulfur on both sides of the reaction varies. To balance the quantities of sulfur, as now on the right side you have an amount of 2, you can add the coefficient to sulfur. The chemical equation is as follows:
2 S + 3 ⇒ 2
Now the amount of elements on each side of the equation is:
Left side: 2 sulfur S and 6 oxygen O (coefficient 3 multiplied by subindice 2)
Right side: 2 sulfur S and 6 oxygen O (coefficient 2 multiplied by subindice 3)
Finally you have the same amount of sulfur and oxygen on both sides of the reaction. So the chemical equation is finally balanced.
