An analogy is a comparison between two things
Example: banana is to yellow as red is to apple OR banana:yellow as red:apple
A metaphor is a figure of speech where a word or phrase is applied and it’s not literal.
Example: it’s raining cats and dogs. It’s not really raining literal cats and dogs. It’s just raining really hard.
Answer: 14.3%Explanation: In order to find the mass percent of hydrogen in this compound, you must determine how many grams of hydrogen you'd get in 100 g of compound.
In your case, you know that an unknown mass of hydrogen reacts with 0.771 g of carbon to form 0.90 g of hydrocarbon, which is a compound that contains only carbon and hydrogen.
Use the total mass of the hydrocarbon to determine how many grams of hydrogen reacted with the carbon.
Now, if 0.90 g of this compound contain 0.129 g of hydrogen, it follows that 100 g of this compound will contain.
So, if 100 g of this compound contain 14.33 g of hydrogen, it follows that the mass percent of hydrogen is 14.3%

Answer: self defense
Explanation: there either scared or feel evil presence so they either attack or escape
The unknown alcohol = 2-propanol
<h3>Further explanation</h3>
Given
volume = 50 ml
mass = 39.4 g
Required
The unknown alcohol
Solution
Density of sample :
= mass : volume
= 39.4 g : 50 ml
= 0.788 g/ml
The unknown alcohol at room temperature = liquid, so the unknown alcohol is 2-propanol because it has temperature range between -90 to 82 for liquid and the density = 0.788 g/ml
