Atoms are like letters of the alphabet and the compounds are like they make are like words this sentence:
Ed helper question
Explanation:
This is very correct atoms can be viewed as elements and compounds the words that are made from them.
Elements are distinct substances that cannot be split up into simpler substances. Such substances are only made up of one atom. This can pictured as alphabets also. They are the fundamental units by which words are formed.Compounds are substances composed of two or more kinds of atoms joined together in a definite grouping. They are like words.

my last 2 chemistry question.
Answer:
1. filtration and evaporation
2. i) water is added to the sand and salt mixture
ii) then the mixture is filtrated and so the sand and the salt water was seperated
iii) the salt water is heated with the help of burner until the water gets evaporated
iv) after the water gets evaporated, the salt is remained in the container
3. observation:
on adding water to the mixture, the salt is completely dissolved in the waterwhen filtrated the sand is seperated from the salt waternow the salt water when heated with the burner until the evaporation, the water is evaporatedthe salt is precipitated and remained in the container4. cautions:
while using the burner, we should be cautious with firethe container that is heated should be holded with the help of a cloth to avoid heatUse the Periodic Table to find molar mass of water.

10. Haley the hummingbird can fly from a pansy flower to a hibiscus flower 20 meters away in 5 seconds.
What is her speed?
Answer:
4
Explanation:
Speed=Distance/time, so 20/5 divide time divided by distance. so the answer is 4.
The speed of Haley the hummingbird is 4 m/s.
From the question,
We are to calculate the speed of Haley the hummingbird
Speed is given by the formula
[tex]Speed =\frac{Distance\ traveled}{Time\ taken}[/tex]
From the given information,
The hummingbird can fly from a pansy flower to a hibiscus flower 20 meters away in 5 seconds.
That is,
The bird can cover a distance of 20 meters in 5 seconds.
Therefore,
Speed of the hummingbird = [tex]\frac{20}{5}[/tex]
Speed of the hummingbird = 4 m/s
Hence, the speed of Haley the hummingbird is 4 m/s.

This diagram shows a ball rolling from left to right along a frictionless surface. In which sections will the ball be subjected to a balanced force?
A. Sections 2 and 5
B. Sections 2 and 3
C. Sections 1 and 4
D. Sections 2, 3, and 5
In sections 1 and 4 the ball is subjected to a balanced force. Hence, option C is correct.
What is the frictionless surface?A Frictionless surface refers to that kind of surface where the force acting on any object which makes it difficult for the object to slide is almost zero or negligible, i.e., no resistance between surface or substance allowing the object to slide and move freely without any friction.
In sections 1 and 4 the ball is subjected to a balanced force. Hence, option C is correct.
