What is the relationship between temperature and kinetic energy?
Answer:
substance is related to the average kinetic energy of the particles of that substance
Explanation:
Answer:
As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

How would I Determine the number of moles in 3.51 x 10^23 formula units of CaCl2
Answer:
by using this formula you will get it
Explanation:
number of mole = number of particles÷ Avogadro's number
n=3.51×10^23÷ 6.02×10^23
n = 0.58 moles

Come up with another myth about the classification of organisms. Then, give two to three reasons why the myth is untrue. Use complete sentences and support your answer with evidence, using your own words.
Your myth:
Fact:
Evidence:
As per questions,
• Myth: A dead organism is the same as a non-living thing in science.
Fact: A dead organism is not the same as a non-living thing in science.
Evidence: A dead organism means that it was once alive, whereas a non-living thing has never been alive.
• Myth: The Linnaeus system of classification will always stay the same.
Fact: The Linnaeus system of classification will pass on .
Evidence: Its new species are being found. Also, Carl Linnaeus came up with a sequential classification of living organism under different taxons namely Kingdom, phylum, class, order, family, genus and species.
• Myth: Tigers and goldfish are not related.
Fact: Tigers and goldfish are related
Evidence: They fall into the same category of vertebrates, which means that both creatures have spines, and internal bone structure.
• Myth: An organism's kingdom only describes physical characteristics.
Fact: An organism's kingdom not only describes physical characteristics.
Evidence: This is evident by that both plant and animal kingdom are classified on the basis of photosynthetic ability. Besides physical characteristics, it also describes its mode of nutrition and food characteristics.
• Myth: Mammals and plants don't belong in the same domain.
Fact: Mammals and plants belong in the same domain.
Evidence: Plants have cells, nucleus, breathing and respiratory capabilities just like mammals.
---------------------★------------------
Your myth: Animals are not related to humans.
Fact: Animals are indirectly related to humans.
Evidence: Humans possessess some unique features found in other species, hence, we are related to apes. At the known time, chimpanzees is our closest relative, and we share up to 98% of the DNA sequence with them.

Type your answer here:
Answer:
1. The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.
2. Limiting factors include a low food supply and lack of space. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.
3. An example of a hypothesis based on observation and scientific principles is:
Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.
A hypothesis is an informed prediction or a tentative statement about what you think that would occur in a scientific experiment as a result of experience from observations accepted by scientific rules and law.
A hypothesis is a testable statement obtained from the research question but questions cannot be tested directly, it is the proposed relationship between the variables that are tested.
An example of a hypothesis is:
Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.
This specifies the direction of the hypothesis because one group is faster than the other.
4. In any ecosystem, organisms and populations with similar requirements for food, water, oxygen or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction. Growth of organisms and population increased are limited by access to resources.
The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.Other part of the question is discussed below:
What is limiting factor?Limiting factors include a low food supply and lack of space. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.
An example of a hypothesis based on observation and scientific principles is that a Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.
A hypothesis is an informed prediction or a tentative statement about what you think that would occur in a scientific experiment as a result of experience from observations accepted by scientific rules and law.
Therefore, The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.

calculate the number of moles in 200 grams of Sodium hydroxide
Answer:
The answer is 5 mol
Explanation:
Number Of Moles = Mass Of Substance ÷ Mass Of One Mole
Mass of NaOH = Molar Mass of Sodium + Oxygen + Hydrogen
23 + 16 + 1
40 g/mol
Number of Mole = 200/40 = 5 mol
Thus, The number of Moles in 200 grams of Sodium hydroxide is 5 mol

An atom has atomic number 5 and mass number 11. How many neutrons does the atom have?
A- 5
B- 6
C- 10
D- 11
Answer:
B
Explanation:
neutrons + atomic number/proton/electron for a neutral atom = mass number
e.g
mass number of Chlorine 35.5
proton number 17
neutron number will be 35.5-17 = 18.5
Therefore.....
your question deduced says
atomic number is 5
mass number is 11
neutron number is however mass number minus atomic number 11-5 =6

Polyatomic ions are made up of two or more types of atoms.
Polyatomic ion:
They are also known as a molecular ion, It is an ion composed of two or more covalently bonded atoms.
They have extra or lesser electrons than they need.
They are charged hence they attract opposite one.
For example-
Therefore, C polyatomic ions are made up of more than one atoms.
Answer:

If a 100. -g sample of a hydrated compound contains 37.07-g sodium, 48.39-g carbonate and 14.54-g water, find the empirical formula
he required empirical formula based on the data provided is Na2CO3.H2O.
What is empirical formula?The term empirical formula refers to the formula of a compound which shows the ratio of each specie present.
We have the following;
Mass of sodium = 37.07-g
Mass of carbonate = 48.39 g
Mass of water = 14.54-g
Number of moles of sodium = 37.07-g/23 g/mol = 2 moles
Number of moles of carbonate = 48.39 g/61 g/mol = 1 mole
Number of moles of water = 14.54/18 g/mol = 1 mole
The mole ratio is 2 : 1: 1
Hence, the required empirical formula is Na2CO3.H2O
