if the combustion of 42.62 g of c4h10 produces 87.85g of co2. what is the percent yield of the reaction? (assume oxygen is in excess.)
The balanced chemical equation for the combustion of C4H10 is C4H10 + 6O2 → 4CO2 + 5H2O.
So,
The moles of C4H10 consumed in the reaction is 42.62 g / (58.12 g/mol) = 0.732 mol.
The moles of CO2 produced in the reaction is 87.85 g / (44.01 g/mol) = 1.99 mol.
The percent yield of the reaction is (1.99 mol CO2 / 0.732 mol C4H10) x 100% = 271.7%.

What is ideal gas law?The ideal gas is the virtual gas that chemists and students dream of because it would be much simpler if there weren't some kind of intermolecular force that would complicate the simple law of the ideal gas. An ideal gas is essentially a point cloud moving with constant random linear motion. Its behavior is described by the assumptions described in the kinetic molecular theory of gases. This ideal gas definition contrasts with the non-ideal gas definition. This is because this equation describes how gases actually behave.
The ideal gas law states that the product of pressure and volume in a gram molecule of an ideal gas is equal to the product of the gas's absolute temperature and the universal gas constant.
PV = nRT
Where, n = number of moles.
P = Pressure (1 atm)
T = Temperature (273 K)
V = Volume (0.5 L)
R = Ideal gas constant (8.314J/K⋅mol)
Now, substitute the values:
1 × 0.5 = n × 8.314 × 273
n = 0.00022 moles
Mg + 2HCl → MgCl₂ + H₂
The mole ratio of Mg and H₂ is 1:1 for the given reaction
Hence the number of moles for Mg will be same as H₂, which is 0.00022 moles.
For the mass of Mg:
m = n × Mm
Where, m = mass
n = number of moles (0.00022 moles)
Mm = molar mass (24.3 g/moles)
m = 0.00486 g

What are the correct coefficients?
_____ H2 + _____ O2 >>>> _____ H2O
Answer: __2__ H[tex]_2[/tex] + __1__ O[tex]_2[/tex] >>>> __2__ H[tex]_2[/tex]O
Explanation:
To balance this equation, we must be sure that the amount of H [hydrogen] and O [oxygen] is the same on both sides. I will be using, and showing, a method my teacher showed me to help us solve.
First, we will write out what we have:
_____ H[tex]_2[/tex] + _____ O[tex]_2[/tex] >>>> _____ H[tex]_2[/tex]O
H 2 >>>> H 2
O 2 >>>> O 1
Then, we see that the O [oxygen] is unbalanced. We will use a coefficient of 2 to balance them. Then, we will multiply this through and see what we now have on the right side, the product.
_____ H[tex]_2[/tex] + _____ O[tex]_2[/tex] >>>> __2__ H[tex]_2[/tex]O
H 2 >>>> H 4
O 2 >>>> O 2
Next, now we see the H [hydrogen] is unbalanced. We will use a coefficient of 2 to balance them. Again, we will multiply it through to see what we have on the left side, the reactants.
After this, the equation is balanced and we have our answer.
__2__ H[tex]_2[/tex] + __1__ O[tex]_2[/tex] >>>> __2__ H[tex]_2[/tex]O
H 4 >>>> H 4
O 2 >>>> O 2
n a titration lab experiment, 8.30 ml of 0.500 m hcl solution was found to neutralize 25.0 ml of sodium hydroxide, naoh. what is the concentration of naoh?
The concentration of naoh =0.166M
What exactly is concentration?The quantity of solute that has been dissolved in a certain volume of solvent or solution is measured by the solution's concentration. A solution that contains a significant amount of dissolved solute is said to be concentrated. A solution is said to be dilute if it only contains a little quantity of dissolved solute.
Given some titration data, we are asked to determine the molar concentration of the NaOH solution.
Let's start by formulating the reaction's chemical equation:
NaOH(aq) +HCl(aq) → NaCl(aq)+H2O(l)
Using the molarity equation, we can find the number of moles of
HCl that reacted:
molarity =mol solute/L soln
mol solute=(molarity)(L soln)
mol HCl = (0.500mol/L) (0.00830L) = 0.00415molHCl
(volume converted to liters)
Now, using the coefficients of the chemical reaction, we can determine the number of moles of
0.00415 mol HCl (1lmol NaOH)/(1mol HCl) =0.00415 mol NaOH
Lastly, we'll use the molarity equation (using given volume of NaOH soln) again to determine the molarity of the sodium hydroxide solution:
molarity = mol solute/Lsoln
M(NaOH)=0.00415 mol/O.O250L = 0.166M
The concentration of naoh =0.166M

The Arrhenius theory, the Brnsted-Lowry theory, and the Lewis theory are the three ideas that have contributed to the definitions of acids and bases over time. According to Arrhenius, an acid is a chemical that, when ionised, releases protons (hydrogen ions) into the solution, whereas a base releases hydroxide ions.
According to Brnsted-Lowry, a base is a proton acceptor and an acid is a proton giver. According to Lewis, a base is an electron-pair donor, while an acid is an electron-pair acceptor
KOH satisfies the Arrhenius theory's definition of a base by producing hydroxide ions when ionised. The hydroxide ion is the base component from a Brnsted-Lowry perspective since it can accept a proton to create water. Although it is a little more difficult to understand from a Lewis perspective why this is a base, the oxygen in the hydroxide has three pairs of non-bonding electrons on it. When a proton (acid) is present, it lacks the electrons necessary to create a covalent link, therefore hydroxide donates an electron pair to the proton in order to build a coordinate covalent bond, which produces water. The three theoretical requirements for a base are thus satisfied by the aforementioned net ionic equation.
