Answer:

nucleotides= DNA, A complex molecule that stores information using four basic coding parts, which are called nucleotides.

genes= Chromosome A collection of genes in a long, single strand of DNA.

genomes= Genomes All the DNA that makes up the complete genetic instruction manual for humans and other organisms.<u><em> </em></u>

The combustion of 0.1240 kg of propane in the presence of excess oxygen produces 0.3110 kg of carbon dioxide. What is the limiti

nadezda [96]

Answer:

The limiting reactant is the propane gas, C₃H₈ while the percentage yield is 83.77%

Explanation:

Here we have

Propane gas with molecular formula C₃H₈, molar mass = 44.1 g/mol combining with O₂ as follows

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Therefore, 1 mole of C₃H₈ combines with 5 moles of O₂ to produce 3 moles CO₂ and 4 moles of H₂O

Mass of propane = 0.1240 kg = 124.0 g

Number of moles of propane = mass of propane/(molar mass of propane)

The number of moles of propane = 124/44.1 = 2.812 moles

The molar mass of CO₂ = 44.01 g/mol

Mass of CO₂ = 0.3110 kg = 311.0 g

Therefore, number of moles of CO₂ = mass of CO₂/(molar mass of CO₂)

The number of moles of CO₂ = 311.0 kg/ 44.01 g/mol = 7.067 moles

Therefore, since 1 mole of propane produces 3 moles of CO₂, 2.812 moles of propane will produce 3 × 2.812 moles or 8.44 moles of CO₂

Therefore;

The limiting reactant is the propane gas, C₃H₈, since the oxygen is in excess

Hence

$The \ percentage \ yield = \frac{Actual \, yield}{Theoretical \, yield} \times 100 = \frac{7.067}{8.44} \times 100 = 83.77 \%$

The percentage yield = 83.77%.

If the length of one side of a square is 12.0 m, what is the perimeter of the square? Express the perimeter with the appropriate

Cerrena [4.2K]

The perimeter of a square whose length is 12.0 m is 48 cm.

<h2>Further Explanation </h2><h3>Area </h3>

Area is a measure of how much space is occupied by a given shape.
Area of a substance is determined by the type of shape in question.

For example;

Area of a rectangle is given by; Length multiplied by width
Area of a triangle = 1/2 x base x height
Area of a circle = πr². where r is the radius of a circle,
Area of a square = S², Where s is the side of the square.etc.

<h3>Perimeter </h3>

Perimeter is defined as the distance along a two dimension shape. Perimeter of different shapes is given by different formulas

For example;

The perimeter of a rectangle = 2(length+width)
The perimeter of a triangle = a+b+c; where a, b and c are the sides of the triangle. etc.

In this case;

We are given one side of a square as 12.0 cm

But Perimeter of a square is given by; 4 × s

Thus; Perimeter = 4 × 12 units

= 48 units
