If 42.68 ml of 0.43 M KOH is used to neutralize 18.40 ml of H, SO4, calculate
the concentration of the sulfuric acid solution.
Write the net ionic equation of this reaction
Answers
The concentration of the sulfuric acid : 0.499 M
The net ionic equation
2 OH ⁻(aq]+ 2 H ⁺ (aq] → 2 H ₂O (l]
Further explanationGiven
42.68 ml of 0.43 M KOH
18.40 ml of H2SO4
Required
the concentration of the sulfuric acid
the net ionic equation
Solution
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence
Input the value :
a=KOH, b= H2SO4
0.43 x 42.68 x 1 = Mb x 18.40 x 2
Mb = 0.499 M
The net ionic equation
Reaction
2KOH + H2SO4 → K2SO4 + 2H2O
2 K ⁺ (aq]+ 2 OH ⁻ (aq] + 2 H ⁺ (aq] + SO ₄²⁻(aq] → 2 K ⁺ (aq] + SO ₄²⁻(aq] + 2 H ₂ O (l]
canceled the spectator ions :
2 OH ⁻(aq]+ 2 H ⁺ (aq] → 2 H ₂O (l]

why is CH3OH more polar than CH3CH2OH
Answers
Answer:
Explanation:
Polarity is about differencens in electronegativity. CH bonds have around the same electronegativity value so a CH bond is nonpolar. The more CH bonds there are in a molecule, the more nonpolar it is. Since CH3CH2OH has more carbon-hydrogen bonds than CH3OH, it is more nonpolar. With the same reasoning, since CH3OH has less CH bonds, it's more polar.

what are the characteristics of temperature
Answers
A Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Fahrenheit and Celsius. The direction that heat energy will spontaneously flow depends on temperature. It measures the average kinetic energy of the substances also.
The average kinetic energy of the particles in an object is measured by its temperature. The velocity of these particles likewise increases as the temperature rises. A thermometer or a calorimeter is used to determine the temperature.
Our weather is made up of several various elements, including temperature, cloudiness, wind speed, and the quantity and type of moisture in the air.
Thus temperature determines the weather and kinetic energy.

Moles of Iron : 1.01
Further explanationGiven
Reaction
Fe2O3 + 3CO → 2Fe + 3CO2
34 liters of CO
Required
moles of Iron
Solution
Assumed at STP
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
so for 34 L :
= 34 : 22.4
= 1.518 moles
From the equation, mol Fe :
= 2/3 x moles CO
= 2/3 x 1.518
= 1.01 moles

Answer:
Not balanced. There are different number of atoms on each side of equation.
Explanation:
Given balanced chemical equation:
Chemical equation:
3C₂H₄ + 3O₂ → 4CO₂ + 6H₂O
The equation is not balanced because umber of moles of C, H and O are not balanced. It consist of six moles of C, 12 moles of H and six moles of oxygen on left side of equation while on right side there are 4 moles of C fourteen moles of oxygen and twelve moles of hydrogen present.
Balanced chemical equation:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O
Now the equation became balanced. There are two moles of carbon, four moles of hydrogen and six moles of oxygen are present on both side of equation.

Find the amount of atoms from 128 grams of NaCl?
Answers
Answer:
13.25 ×10²³ atoms
Explanation:
Given data:
Mass of NaCl = 128 g
Number of atoms = ?
Solution:
First of all we will calculate the number of moles of NaCl.
Number of moles = mass/molar mass
Number of moles = 128 g/ 58.4 g/mol
Number of moles = 2.2 mol
Number of atoms:
1 mole of any substance contain 6.022×10²³ atoms.
2.2 mol × 6.022×10²³ atoms / 1mol
13.25 ×10²³ atoms

Answers
Explanation:
Given:
20.5 torr
78.6 torr
225 torr
Change into atm
Computation:
We know that;
1 torr = 0.00131579 atm
So,
1. 20.5 torr
= 20.5 x 0.00131579 atm
= 0.02697
= 0.027 atm (Approx)
2. 78.6 torr
= 78.6 x 0.00131579 atm
= 0.103090
= 0.103 atm (Approx)
3. 225 torr
= 225 x 0.00131579 atm
= 0.2960
= 0.296 atm (Approx)
