Answer: [tex]O_2[/tex] is the limiting reagent, 180 g of water is produced
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} H_2=\frac{24.0g}{2g/mol}=12moles[/tex]
[tex]\text{Moles of} O_2=\frac{160.0g}{32g/mol}=5moles[/tex]
[tex]2H_2+O_2\rightarrow 2H_2O(g)[/tex]
According to stoichiometry :
1 mole of [tex]O_2[/tex] require 2 moles of [tex]H_2[/tex]
Thus 5 moles of [tex]O_2[/tex] will require=[tex]\frac{2}{1}\times 5=10moles[/tex] of [tex]H_2[/tex]
Thus [tex]O_2[/tex] is the limiting reagent as it limits the formation of product and [tex]H_2[/tex] is the excess reagent.
As 1 mole of [tex]O_2[/tex] give = 2 moles of [tex]H_2O[/tex]
Thus 5 moles of [tex]O_2[/tex] give =[tex]\frac{2}{1}\times 5=10moles[/tex] of [tex]H_2O[/tex]
Mass of [tex]H_2O=moles\times {\text {Molar mass}}=10moles\times 18g/mol=180g[/tex]
Thus 180 g of [tex]H_2O[/tex] will be produced from the given masses of both reactants.

A bullet seized from a crime scene has a composition of lead 11.6 g, tin 0.5 g, and
antimony 0.4 g. What is the percentage of lead in the bullet? Express your answers to
the ones place.
Answer:
92.8%
Explanation:
Step 1: Given data
Mass of lead in the bullet (mPb): 11.6 gMass of tin in the bullet (mSn): 0.5 gMass of antimony in the bullet (mSb): 0.4 gStep 2: Calculate the total mass of the bullet
The total mass of the bullet is equal to the sum of the masses of the elements that form it.
m = mPb + mSn + mSb = 11.6 g + 0.5 g + 0.4 g = 12.5 g
Step 3: Calculate the mass percentage of Pb in the bullet
We will use the following expression.
%Pb = mPb / m × 100%
%Pb = 11.6 g / 12.5 g × 100% = 92.8%

Answer:
[tex]= 3.105x10^{24}molecules\ acetone[/tex]
Explanation:
Hello!
In this case, given the volume of acetone, it is possible to compute the mass and next the moles via its molar mass (58.08 g/mol) as shown below:
[tex]n_{acetone}=380mL*\frac{0.788g}{1mL} *\frac{1mol}{58.08 g} \\\\n_{acetone}=5.16mol[/tex]
Then, via the Avogadro's number it is possible to compute the acetone molecules as follows:

Answer:
ions are deflected and the lighter the ions the more the deflection.
Placing magnetic field in the path of the ions cause them to move in a curved path.
Explanation:
This question is all about the way in which mass spectroscopy works. Mass spectroscopy Is one of the techniques in spectroscopy which is used in the identification of chemical compounds.
Mass spectroscopy works based on the principle of ionization. For a mass spectroscopy to start ionization must first occur that is to say this is the first step in the identification of compound in mass spectroscopy.
The following steps are involve in mass spectroscopy;
=> Ionization: the molecules of the sample are first ionized. The ions formed here are positive ions.
=> Acceleration: the ions in step one are accelerated.
=> Deflection: the smaller ions get deflected more than the bigger ions. The magnetic field is used in the deflection of this ions.
=> Detection: the ions are then detected.
Therefore, to answer the question, the ions are deflected and the lighter the ions the more the deflection.
Placing magnetic field in the path of the ions cause them to move in a curved path.

What happens when a base dissolves?
A. It increases the concentration of OH in solution.
B. It increases the concentration of H+ in solution.
C. It adds oxygen to the solution.
D. It is no longer dangerous.
Answer:
A. It increase the concentration of OH in solutions.
Explanation:
Bases are substances that react with and neutralise acids, producing water. When dissolved, bases release hydroxide ions, OH-(aq) into solution.
When a base dissolves, it increases the concentration of OH⁻ ions in the solution. Therefore, option A is correct.
What are acids and bases?An acid can be described as a substance that is capable of donating a hydrogen ion to another substance. A base can be described as a molecule or ion that is able to have a hydrogen ion from an acid.
Acidic materials are commonly identified by sour taste. An acid can be considered commonly a molecule that can donate an H⁺ ion and can be energetically favorable after a loss of H⁺ ion. Acids increase the concentration of H⁺ ions in solution.
Bases are described by a bitter taste and a slippery nature. A base or alkali increases the concentration of OH⁻ ions in the solution. When bases react with acids, they give salts and water as products.
The pH range on the pH scale of the acids lies between 0 to 7 and the pH range of the bases lies between 7 to 14.

A continuously stirred tank reactor is designed to remove the hazardous waste compound trichloroethylene (TCE) from industrial wastewater. The tank is 3250 liters. The wastewater flows into the tank at 200 L/min with a TCE concentration of 25 mg/L. The reactor decays TCE at a reaction rate of 0.20 min-1 . What is the steady-state concentration of TCE in the treated water leaving the reactor
Answer:
the steady-state concentration of TCE in the treated water leaving the reactor is 5.88 mg/L
Explanation:
Given that;
Tank volume v = 3250 liters
wastewater flows into the tank Q = 200 L/min
TCE concentration Co= 25 mg/L
reactor decays TCE at a reaction rate K = 0.20 min-1
mass balance
we know that;
Accumulation = inflow - outflow ± generation
⇒dc/dt = QCo - Qc ± rc.V
now at a steady state; dc/dt = 0
so
0 = QCo - Qc + rcV
where rc = -kc
0 = QCo - Qc - kcV
Qc + kcV = QCo
c(Q + kV) = QCo
c = QCo / (Q + kV)
so we substitute
c = (200 × 25) / (200 + (0.2×3250))
c = 5000 / 850
c = 5.88 mg/L
Therefore, the steady-state concentration of TCE in the treated water leaving the reactor is 5.88 mg/L

A silver nitrate solution contains 14.77 g of primary standard AGNO3 ( Molecular weight 169.87) in 1.00 L. What volume of this solution will be needed to react with 0.2631 g of NaCl ( Molecular weight 58.44) ?
Answer:
[tex]V=5.2 mL=0.052L[/tex]
Explanation:
Hello!
In this case, since the chemical reaction between silver nitrate and sodium chloride is:
[tex]AgNO_3(aq)+NaCl(aq)\rightarrow AgCl(s)+NaNO_3(aq)[/tex]
We can see there is a 1:1 mole ratio between each solution; thus, we first compute the moles of each reactant considering their molar masses:
[tex]n_{AgNO_3}=14.77g*\frac{1mol}{169.87g}=0.087molAgNO_3\\\\ n_{NaCl}=0.2631g*\frac{1mol}{58.44}=0.0045molNaCl[/tex]
Now, since the concentration of the silver chloride solution is 0.087 M, we may assume that the concentration of the NaCl solution is the same, so we can compute the volume as shown below:
[tex]V=\frac{n_{NaCl}}{M}=\frac{0.0045mol}{0.087mol/L}\\\\V=0.052L[/tex]
Or:
[tex]V=5.2 mL[/tex]
Best regards!
The volume of solution needed to react with 0.2631 g of NaCl is 0.052 L.
How we calculate the volume?Volume of the solution will be calculated by using the below formula:
M = n/V, where
M = concentration in terms of molarity
n = no. of moles
V = volume
Given chemical reaction is:
AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)
First we calculate the moles of given reactants by using the formula:
n = W/M , where
W = given mass
M = molar mass
Moles of AgNO₃ = 14.77g / 169.87g/mole = 0.087 mole
Moles of NaCl = 0.2631g / 58.44g/mole = 0.0045 mole
Concentration of AgNO₃ = 0.087 mole / 1L = 0.087M
From the stoichiometry of the reaction it is clear that mole ration of AgNO₃ & NaCl is 1:1. So, we take the concentration of NaCl is equal to the concentration of AgNO₃ and calculate the volume by using the above formula as:
Volume of NaCl = 0.0045mole / 0.087M = 0.052 L
Hence, 0.052 L is the required volume of NaCl.
