What is the straightforward meaning of volume?The volume of an item in three dimensions is the area occupied inside its boundaries. It is referred to as the object's capability on occasion..
BriefingNumber of moles per solute (KI) per volume of water (KI + water) is how molarity is defined.
Additionally, we require the molar mass for KI, which is 166 g/mol.
Procedure:The number of moles of KI = 2.08 g/166 g/mol = 0.0125 moles KI
Volume = 279 mL = 0.279 L (1 L = 1000 mL)
Therefore,0.125 moles KI ------- 0.279 L of solution
X ------- 1 L of solution
X = 0.448 mol/L
Another procedure:Molarity = number of moles (KI)/Volume of solution (L)
Molarity = 0.125 moles/0.279 L = 0.448 mol/L or M
Answer: M = 0.448 mol/L

ammonia chemically reacts with oxygen gas to produce nitric oxide and water . what mass of nitric oxide is produced by the reaction of 1.37g of oxygen gas?
Nitric oxide weighs 0.77 grams and is created by the reaction of 1.37 grams of ammonia.
What does oxygen contain?Chemical elements, like oxygen, are compounds that only have one type of atom. An oxygen atom has 8 protons through its nucleus, which is why it has an electron density of eight and the chemical symbol O. At ambient temperatures, oxygen is a colorless, odorless gas.
The equation for the reaction of ammonia and oxygen to produce Nitric oxide and water is,
4NH₃ + 5O₂ → 4NO + 6H₂O
From the reaction we can see,
4 moles of ammonia = 4 moles of nitrix oxide.
Mole of ammonia = moles of nitric oxide.
Moles = reacted/formed mass/ molar mass
Molar mass of ammonia = 17 g/mol.
Molar mass of nitric oxide = 30 g/mol.
Mass of ammonia reacted = 1.37 grams.
Putting values,
1.37 x 17 = Formed mass of nitric oxide x 30
Formed mass of nitric oxide = 0.77 grams.

which one of the following elements has the largest atomic radius? question 18 options: a) al b) b c) o d) p e) f
The element which has the largest atomic radius is Aluminium. Therefore, the correct answer is option A- Al has the largest atomic radius.
We are aware that when atomic number increases, the number of shells also rises and, consequently, does atomic radius down a group in the periodic table. Along a period, as the atomic number rises, the nuclear charge rises as well, leading to an increase in the nuclear force of attraction. As a result, atomic radius shrinks over time.
Since the third period is below the second period, it will have a bigger atomic radius than the second period.
In the periodic table, aluminum and boron both belong to the same group. Atomic radius tends to rise from top to bottom within a group, according to this trend. The fact that aluminum is included in the periodic table below boron indicates that it has a bigger atomic radius than boron.

how does knowing the states of matter help to explain any difference in mass from the reactants to the products?
The process is a change of state, dissolving, or a chemical reaction, the total mass of the substances does not change.
French chemist Antoine Lavoisier established the law of conservation of mass in 1789. According to the rule of conservation of mass, a chemical process cannot generate or destroy matter.
For instance, when wood burns, the mass of the gases, soot, and ashes is equal to the amount of the charcoal and oxygen before the reaction began. Thus, the mass of the reactant and the mass of the product are equal. A product is the material created as a result of a chemical reaction, whereas a reactant is the chemical reaction of two or more elements to create a new substance. Although matter and the associated mass cannot be generated or destroyed, they can change into other substances such as liquids, gases, and solids.

cpmpute the composition of the iron carbon alloy for which the mass fraction of total ferrite and total cementite are 0.88 and 0.12 what is the protectoid phase
In this problem we are given values of Wα and WFe3C for an iron-carbon alloy (0.88 and 0.12,respectively), and then are asked to specify whether the alloy is hypoeutectoid or hypereutectoid.
Employment of the lever rule for total α leads to
W[tex]\alpha[/tex] = 0.88 = [tex]\frac{CFe3C- C0}{CFe3C - \alpha }[/tex] = [tex]\frac{6.70 -C0}{6.70- 0.022}[/tex]
Now, solving for C0, the alloy composition, leads to C0 = 0.82 wt% C. Therefore, the alloy is hypereutectoid since C0 is greater than 0.76 wt% C.
What is the protectoid phase?
The term proeutectoid refers to a phase that develops (on cooling) before eutectoid austenite decomposes. It is similar to primary solids in that it is the first phase to solidify after the austenite phase has solidified.
How do you find the Proeutectoid phase?
On a phase diagram, the proeutectic point is the temperature at which the mixture transforms into a mixture of two solids. There are two proeutectic temperatures. One happens at 1587°C, where everything over this temperature is liquid.

Therefore, only the d 6 electron configuration can give rise to both LS and HS complexes in the presence of strong and weak ligand fields, respectively.

how does the reaction rate change when the nitrogen monoxide concentration is doubled and chlorine concentration is halved? defined term
When the concentration of nitrogen monoxide is doubled and the concentration of chlorine is cut in half, the reaction is second order in nitrogen monoxide, NO.
Is NOx equivalent to NO2?
Nitric oxide (NO), an odorless, colorless gas, and nitrogen dioxide (NO2), a reddish-brown gas with an offensive odor, are the two gases that are typically referred to as "nitrogen oxides" (NOx). Nitrogen dioxide is created when nitric oxide combines with oxygen or ozone in the atmosphere.
N2O is a laughing gas, right?
A non-flammable, colorless, and odorless gas is nitrous oxide. Despite not being flammable, nitrous oxide will nonetheless facilitate combustion to the same degree as oxygen. It produces a mood of exhilaration, therefore the moniker "laughing gas." The least effective inhalational anesthetic is nitrous oxide.

Most molecular solutesCH3OH (methanol)Table sugarA substance that forms an aqueous solution but does not conduct electricity.What are electrolytes and non-electrolytes?Electrolytes are some substances that can release electrical charges in the form of cations (positive charge) and anions (negative charge). These electrical charges move freely in the aqueous form as a soluble ionic solution. The freely-moving molecules can conduct electricity. On the other hand, non-electrolytes do not contain anions and cations. Hence, they cannot conduct electricity.
