How many moles of I2 are in 8.23 moles of NaI ?
Answers
Answer: 4.12
Explanation:
we know that the given mol is 8.23 mol and they are 2NaI and I2 so we will write the equation like this.
8.23mol NaI x 1mol of I2 ÷ 2molNaI = 4.115≅ 4.12 mol of I2

A rectangular poster is /4 yard wide and / yard tall. What is its area? Solve this problem any way you choose
Answers
Answer:
Area of rectangular poster = [tex]\frac{3}{16}[/tex] yard²
Explanation:
P.S - The exact question is -
Given - A rectangular poster is [tex]\frac{1}{4}[/tex] yard wide and [tex]\frac{3}{4}[/tex] yard tall.
To find - What is its area ?
Proof -
We know that ,
The area of rectangle = Length × Breadth
Here,
Given that,
Length of rectangle = [tex]\frac{3}{4}[/tex] yard
Breadth of rectangle = [tex]\frac{1}{4}[/tex] yard
∴ we get
Area of rectangular poster = [tex]\frac{3}{4}[/tex] × [tex]\frac{1}{4}[/tex] yard²
= [tex]\frac{3}{16}[/tex] yard²
⇒Area of rectangular poster = [tex]\frac{3}{16}[/tex] yard²

If 3.22 g of precipitate are recovered from the reaction of limewater (Ca(OH),) with carbon dioxide to produce
water and calcium carbonate, what is the percent yield if 20.0 g of carbon dioxide was mixed with the
limewater?
the correct answer is 7.1% but i don't understand what they did
Answers
Answer:
Percent yield = 7.1%
Explanation:
The general reaction of the problem is:
Ca(OH)₂ + CO₂ → H₂O + CaCO₃
To solve this question we need to find theoretical yield using the amount of carbon dioxide added because:
Percent yield = Actual yield (3.22g) / Theoretical yield * 100
Theoretical yield is the maximum amount of product that could be obtained. To find it we need to convert the mass of CO₂ to moles. The moles of CO₂ = Moles of CaCO₃:
Moles CO₂ -Molar mass: 44.01g/mol):
20.0g * (1mol / 44.01g) = 0.454 moles CO₂ = Moles of CaCO₃ produced
Mass CaCO₃ = Theoretical yield -Molar mass: 100.09g/mol-:
0.454 moles * (100.09g / mol) = 45.5g of CaCO₃ = Theoretical yield.
Replacing:
Percent yield = 3.22g / 45.5g * 100
Percent yield = 7.1%It late, I need help quick

The molar mass of two equally sized samples of unknown gaseous compounds is shown in the table. Molar Mass Comparison Gas Molar Mass A 17 g/mol B 36.5 g/mol Which statement describes the density and diffusion of both gases at STP? Gas A has a higher density and diffuses faster than Gas B. Gas A has a higher density and diffuses slower than Gas B. Gas A has a lower density and diffuses faster than Gas B Gas A has a lower density and diffuses slower than Gas B.
Answers
Answer:
Effusion is the process of a gas being poured out through a hole diametrically smaller than the structural exit of the container.
A lighter gas effuses faster than a heavier gas.
Thus gas A has a lower density and effuses slower than Gas B.
Explanation:
The gas with a lower molar mass will have a lower density and diffuses at a slower rate. Thus gas A has a lower density than gas B and diffuses slower than gas B.
Three points should be noted here;
The density of any substance is related to the molar mass.[tex]D=M/V[/tex], where [tex]D[/tex] is the density, [tex]M[/tex] is the mass and [tex]V[/tex] is the volume of the substance.The density of the gas is directly proportional to the molar mass of the gas.Hence the gas A has lower density and the gas B has higher density as the molar mass of A is [tex]17 g/mol[/tex] and of B is [tex]36.5 g/mol[/tex].
About Diffusion please note the below points;
Diffusion is the process of movement of a substance from the area of higher concentration to the area of lower concentration.The gas with a smaller mass will diffuse slower in rate than the gas with a higher mass.Hence the gas A diffuses slower in rate than gas B.
Thus the correct answer is "Gas A has a lower density and diffuses slower than Gas B".

b)8.25 g
c)85.0 g
d)91.5 g
Answers
Answer:
a)82.5 g
Explanation:
To solve this problem we will use Avogadro's number, which states the number of formula units per mole.
8.50x10²³formula units ÷ 6.023x10²³ formula units/mol = 1.41 molThen we convert 1.41 moles of NaCl to grams, using its molar mass:
1.41 mol NaCl * 58.44 g/mol = 82.4 gThe closest answer is option a).

2. Hydrocarbons consist of carbon and hydrogen. 5.7 g of a hydrocarbon contains 4.8 g of carbon.
If the relative molecular mass of the hydrocarbon is 114, determine its molecular formula.
Answers
Answer:
The molecular formula of the hydrocarbon compound is C₈H₁₈
Explanation:
The type of chemical substance in the question = Hydrocarbon
The mass of the hydrocarbon = 5.7 g
The mass of carbon in the given hydrocarbon (sample) = 4.8 g
The relative molecular mas of the hydrocarbon = 114 g
Therefore, the mass of hydrogen in the sample, H = 5.7 g - 4.8 g = 0.9 g
The ratio of the mass of carbon in the sample = 4.8/5.7
The ratio of the mass of hydrogen in the sample = 0.9/5.7
By the law of constant composition, we have;
The mass of carbon in a mole of the hydrocarbon = (4.8/5.7) × 114 g = 96 g
The molar mass of carbon, C = 12 g/mol
The number of moles of carbon in a mole of the hydrocarbon, 'n₁', is given as follows;
n₁ = 96 g/12 g = 8 moles
The mass of hydrogen in a mole of the hydrocarbon = (0.9/5.7) × 114 g = 18 g
The molar mass of hydrogen, H ≈ 1 g/mol
The number of moles of hydrogen in a mole of the hydrocarbon, 'n₂', is given as follows;
n₂ = 48 g/1 g = 18 moles
Therefore, in each each molecule of the compound, we have have 8 atoms of carbon, 'C', and 18 atoms of hydrogen, 'H'
Therefore, we get;
The molecular formula of the hydrocarbon compound is C₈H₁₈ which is the chemical formula for the hydrocarbon also known as octane

1. If you have 5g of pennies how many dozen pennies do you have?
Answers
Answer:
15.69 dozen
Explanation:
Mass of penny = 5 g
Dozens of penny =..?
Next, we shall convert 5 g to gross. This can be obtained as follow:
3824 g = 1000 gross
Therefore,
5 g = 5 g × 1000 gross / 3824 g
5 g = 1.3075 gross
Thus, 5 g is equivalent to 1.3075 gross.
Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:
1 gross = 12 dozen
Therefore,
1.3075 gross = 1.3075 gross × 12 dozen / 1 gross
1.3075 gross = 15.69 dozen
Thus, 5 g of penny is equivalent to 15.69 dozen
