The animal kingdom is large and diverse. Scientists discover new species all the time, and they need a way to classify them. The

science of classification is called taxonomy. In taxonomy, every kingdom of life (plant, animal, fungus, etc) branches into smaller groups called phyla. Each phylum branches into classes, and so on down to species. The presence or absence of a backbone is one of the first traits that scientists use to classify animals. Animals without a backbone are invertebrates. There are many phyla of invertebrates. Earthworms, spiders, jellyfish, starfish and butterflies are all examples of invertebrate animals. Animals with a backbone are vertebrates.
Which of these is an example of an invertebrate?

A
an oak tree, which is a kind of plant
B
a mushroom, which is a kind of fungus
C
a bat, which is an animal with a backbone
D
a snail, which is an animal without a backbone

<h3>Answer:</h3>

C6H12O6

Explanation:

To find empirical formular you write out the element

Carbon Hydrogen Oxygen

3.96 769 5.28

then u althrough divide by their atomic numbers

3.96÷ 12 769÷1 5.28÷16

=0.33 =769 =0.33

also divide althrough by the lowest number

the lowest number is 0.33 so we use it to divide

0.33÷0.33. 769÷0.33. 0.33÷0.33

= 1 = 2 = 1

empirical formular= CH2O

To find the Molecular formular

Molecular number = molar mass

(CH2O)n = 182

(12+1×2+16)n = 182

30n = 182

n = 6

therefore the Molecular formular is C6H12O6

a solution contains 3.00mol of Potassium bromide in 10.0 mol of water. What is the mole fraction of potassium bromide​
stiks02 [169]

mole fraction of potassium bromide = 0.23

Explanation:

We define mole fraction of a specific compound in a mixture as:

mole fraction of a compound = number of moles of the compound / total number of moles

in our case we have:

number of moles of potassium bromide = 3 moles

total number of moles = number of moles of potassium bromide + number of moles of water

total number of moles = 3 + 10 = 13 moles

mole fraction of potassium bromide = 3 / 13 = 0.23
