How to convert 104 Km to M
Answer:
m=104000
Explanation:
by 1km=1000m
104km=?
Now
104km=104×1000m
=104000m
Therefore,m=104000 ans
104 kilometers is equal to 104,000 meters.
A conversion factor is a ratio that shows how two different units of measurement relate to each other. You can convert a value from one unit to another by multiplying or dividing the original value by a conversion factor.
For example,
Since there are 1000 meters in a kilometer, we need to multiply the distance in kilometers by 1000 to convert it into meters.
So, to convert 104 kilometers to meters:
104 Km * 1000 = 104,000 meters
Therefore, 104 kilometers is equal to 104,000 meters.

what evidence have you discovered to explain how the fossil record provides relative ages? use the words: mass extinction, superposition, fossils, and relative age
Answer:
Relative dating is based on the positions of fossils in rock layers. Lower layers were laid down earlier, so they are assumed to contain older fossils. This gives the fossil an approximate age in years. Absolute dating is often based on the amount of carbon-14 or other radioactive element that remains in a fossil up until extinction.
Relative dating is a method of dating where the geologic events are arranged and the rocks are left behind in a sequence. They function on the basis of the stratigraphy and don't provide us with actual numeric data.
It provides us with the relative ages such as mass extinction the fossils are superimposed. It is based on the position of fossils in the layers of the rocks.Learn more about the discoveries to explain how the fossil record.

Cl₂-CH₄-SO₂-CH₂O-C₂H₄.
thank you!
Answer:
C₂H₄-CH₄-CH₂O-SO₂-Cl₂
Explanation:
The arrangement of gases in increasing order of the number of atoms that make up its molecule, from left to right, is C₂H₄-CH₄-CH₂O-SO₂-Cl₂.
What are gases?
Gas is one of the matters. It's invisible, and its particles are present very far away from each other. The atoms of the gas move randomly, and they are always in motion.
There are iii kinds of matter, solid, liquid, and gas. When there is a modification in temperature when there is a rise in temperature the solid becomes liquid and eventually, the liquid becomes gas.
The arrangement of gases in it increases the order of the number of atoms. So it can be identified by seeing the moles of elements that are shown in the chemical formula of gas.
Thus, the arrangement of gases is C₂H₄-CH₄-CH₂O-SO₂-Cl₂.

Polar molecules have partial positive and partial negative charges. An electrical
attraction between the partial positive charge of one polar molecule and the partial
negative charge of another polar molecule is called a/an
Answer:
Image result for Polar molecules have partial positive and partial negative charges. An electrical attraction between the partial positive charge of one polar molecule and the partial negative charge of another polar molecule is called a/an
A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H2O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other.

GIVING 20 POINTS!! Apply Concepts Two chemists each plan an investigation in which they will combine hydrogen gas with chlorine gas to observe the chemical reactivity. The plans differ in that one will use 25 milligrams each of hydrogen and chlorine, and the other will use 1000 times this amount, i.e., 25 grams each of hydrogen and chlorine. Can the investigations reach similar conclusions about the reactivity of hydrogen with chlorine? Explain.
Answer:
Yes, the investigations will reach similar conclusions about the reactivity of H2 and Cl2
Explanation:
1. The law of multiple proportions says that when elements form compounds, the proportions of the elements in those chemical compounds can be expressed in small whole number ratios. This means that regardless of whether 1000 times more of the products are used, the reactivity of the products is established by the chemical reaction
2. The law of multiple proportions is an extension of the law of definite composition, which states that compounds will consist of defined ratios of elements.
3. A reaction with more reactants will need more care because more products are produced, which can be toxic
4. H2 and Cl2 reactivity does not depend on the quantities but the chemical properties of each compound

What are significant figures?Significant figures are used for establishment of a number which is presented in the form of digits. These digits give a meaningful representation to the numbers.
The significant figures are the significant digits which convey the meaning according to the accuracy. These provide precision to the numbers and hence are called as significant numbers.There are rules for counting significant figures which are as follows:
1)All non-zero digits are significant .
2)All zeroes which occur between non-zero digits are significant.
3)All zeroes to the left and right of a non-zero digit are not significant.
4) All zeroes on right of decimal are significant if a non-zero number follows them.
5)All zeroes on right side of non-zero digit are significant
