The order of [NO] is 2.
The rate law for a chemical reaction is an equation that describes how the rate of the reaction changes with respect to the concentrations of the reactants. In this case, the rate law for the reaction 2NO(g) + O2(g) → 2NO2(g) is Rate = k[O2][NO]^2.
The order of a reactant in a rate law is determined by the exponent to which its concentration is raised. In this case, the concentration of NO is raised to the power of 2, so the order of [NO] is 2. This means that the rate of the reaction is directly proportional to the square of the concentration of NO. Therefore, as the concentration of NO increases, the rate of the reaction will increase at a faster rate.

What is called proton number?
Proton number is called atomic number.
The chemical element's atomic number, also referred to as the nuclear charge number, is determined by the charge number of an atomic nucleus. This is the quantity of protons in the nucleus of each of that element's atoms. The atomic number refers to the number of protons in the nucleus of an atom. The amount of protons in an element determines what kind of element it is.
Both protons and electrons are equal in number in a neutral atom. The mass of an atom, represented by the letter M, is equal to the total of its protons and neutrons in the nucleus.
The number of protons in the atom's nucleus is therefore equal to the atomic number (Z). in an uncharged atom.

Estimate the net charge at pH=7. Assume the pKa values given in the table above. Term____
The net charge at pH=7. The pKa values given in the table above will term is referred as neutral.
At pH = 7, the solution is considered neutral, which means that the concentration of H+ ions is equal to the concentration of OH- ions, i.e [H+] = [OH-] = 10^-7 M.
To estimate the net charge at pH = 7, you would need to know the pKa values of the acid and the species present in the solution. It is important to note that the net charge at pH 7 will depend on the acid and species present in the solution, and the pKa values given for that specific acid. In a neutral solution, the pH is equal to 7, which means that the concentration of H+ ions is equal to the concentration of OH- ions. Since the pH is neutral, this means that the solution has no net charge. Neutral solutions contain equal concentrations of positive and negative ions, thus the net charge is zero.

A compound is found to contain 10.37 % phosphorus, 4.689 % nitrogen, and 84.95 % iodine by weight. The molecular weight for this compound is 298.8 g/mol. What is the molecular formula for this compound
Answer:
P₂N₂I₄
Explanation:
Firstly, we calculate the empirical formula of the compound. To do this we find the moles of each element. Treat the percentages as masses.
The formula for moles is:
[tex]moles = \frac{mass}{relative \: atomic \: mass}[/tex]
The masses of each element are:
Phosphorus = 10.37g
Nitrogen = 4.689g
Iodine = 84.95g
The relative atomic masses of each element are:
Phosphorus = 31.0
Nitrogen = 14.0
Iodine = 126.9
Using these values, we can calculate the moles of each element:
[tex]moles \: of \: phosphorus = \frac{10.37}{31.0} = 0.335[/tex]
[tex]moles \: of \: nitrogen \: = \: \frac{4.689}{14.0} = 0.335[/tex]
[tex]moles \: of \: iodine \: = \: \frac{84.95}{126.9} = 0.669[/tex]
Using the moles, write them in a ratio to find the ratio of moles:
Phosphorus : nitrogen: iodine
0.335 : 0.335: 0.669
The smallest number here is 0.335, so divide each number by 0.335
0.335÷0.335=1
0.335÷0.335=1
0.669÷0.335=1.99... = 2 (round to the nearest whole number)
These numbers are used as the subscripts of each element.
This means that the empirical formula is:
PNI₂
To calculate the molecular formula:
[tex]\frac{molar \: mass \: of \: molecular \: formula}{molar \: mass \: of \: empirical \: formula}[/tex]
The molar mass of empirical formula is adding the molar masses of compound PNI2:
31.0 + 14.0 + 126.9 = 171.9
The molar mass of molecular weight or mass = 298.8 (given from the question)
Substitute these in the formula above:
[tex] \frac{298.8}{171.9} = 1.738...[/tex]
1.738 = 2 rounded to the nearest whole number.
Multiply all the subscripts seen in the empirical formula by the number 2:
PNI₂ × 2 = P₂N₂I₄

What volume (in L) of nitrogen will be produced from the reaction of 6. 8 L of carbon monoxide?
2CO(g)+2NO(g)>N2(g)+2CO2(g)
The volume of nitrogen produced from the reaction of 6.8 L of carbon monoxide is 3.7 L
In order to determine the volume of nitrogen produced from the reaction of 6.8 L of carbon monoxide, we need to use the balanced equation for the reaction:
2CO(g) + 2NO(g) -> N2(g) + 2CO2(g)
From the equation, we can see that for every 2 moles of CO that react, 1 mole of N2 is produced. The volume of a gas is directly proportional to the number of moles of the gas present.
If the initial volume of CO is 6.8 L, we can assume that the number of moles of CO is
6.8 L / 24.45 L/mol = 0.278 mol.
Therefore, the number of moles of N2 produced would be
0.278 mol CO * (1 mol N2 / 2 mol CO) = 0.139 mol N2.
Finally, using the ideal gas law PV = nRT (where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature), we can calculate the volume of N2 produced:
V = nRT / P
V = 0.139 mol N2 * (8.314 J/mol*K) * (273 K) / (1 atm) = 3.7 L
So, the volume of nitrogen produced from the reaction of 6.8 L of carbon monoxide is 3.7 L.

what is the likely composition of the indicator solution when the intermediate or transistion color is observed in step 6
A blend of dyes called a universal indicator gradually changes color throughout a pH range of 4 to 14. The color serves as a direct indicator of pH.
Thymol blue, methyl red, bromothymol blue, and phenolphthalein are the primary ingredients of a universal indicator in the form of a solution. Colors ranging from yellow to red denote an acidic solution, whereas colors ranging from blue to violet denote an alkaline solution and green denotes a neutral solution. Substances called indicators are those whose solutions change color as the pH changes. We refer to these as acid-base indicators. The conjugate base or acid versions of these typically weak acids or bases have various hues because of variations in their absorption spectra.
