Answer:
Explanation:
The<em> mole fraction</em> of a component in a mixture is the number of moles of the component divided by the total number of moles of all the components, multiplied by 100.
The symbol X is used to represent the mole fraction.
<u />
<u>1. Convert masses in grams to number of moles</u>
Formula:
- number of moles = mass in grams / molar mass
a) Lithium bromide
- Chemical Formula: LiBr
- Molar mass: 86.845 g/mol
b) Water
c) Total number of moles = 2.00 mol + 20.0 mol = 22.0 mol
<u>2. Mole fraction of lithium bromide</u>
In rainbow, the color that has the longest wavelength is red which means option 5 is the correct choice.
Dispersion is described to be the spreading of white mild into its complete spectrum of colors, in truth we also can say a complete spectrum of wavelengths. The white mild turns into from solar and includes seven colors. On one end of the spectrum is red with the longest wavelength. Blue or violet mild has the shortest wavelength. White mild is a aggregate of all hues withinside the color spectrum. The colors of the rainbow are: Red, orange, yellow, green, blue, indigo, violet.
Therefore, option 5 is the correct choice.

Answer:
Y: tRNA
Z: DNA
Explanation:
This question involves two different nucleic acid molecules that are involved in protein production. Xavier used a chart to highlight the functions these nucleic acids perform during protein synthesis.
- Transfer RNA known as tRNA is a type of RNA molecule found in the ribosomes. It functions to read the mRNA codon and carry corresponding amino acid to the ribosomes for linking with one another. Based on this, "Y" on the chart is a tRNA molecule.
- Deoxyribonucleic acid, also known as DNA, is a molecule found in the NUCLEUS whose function is to store the genetic information in the cell. DNA carries the information needed for the synthesis of protein. Based on this, Z is a DNA molecule.
Answer:
<h2>59.1 m</h2>
Explanation:
The height of the object can be found by using the formula
where
p is the potential energy
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
We have the final answer as
<h3>59.1 m</h3>
