This name tells us that the molecule has three carbons and has a double bond in it.
pro means three carbons when talking about hydrocarbons
ene means the presence of at least 1 double bond
ane means all single bonds and yne means at least one triple bond which means that propane is a three carbon molecule with only single bonds connecting them while propyne has three carbons with a triple bond between 2 of the carbons.
I hope this helps. Let me know if anything is unclear.
I believe the correct answer would be the last option. All of the quantities given above contain the same number of particles. We determine this by using the avogadro's number. It represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole.
2 moles of carbon atoms ( 6.022 x 10^23 particles / mole ) = 1.20 x10^24 particles
<span>
2 moles of carbon dioxide molecules </span>( 6.022 x 10^23 particles / mole ) = 1.20 x10^24 particles<span>
2 moles of diatomic oxygen molecules </span>( 6.022 x 10^23 particles / mole ) = 1.20 x10^24 particles
As you can see, no matter what is the gas as long as they have the same number of moles, they would also have same number of particles<span />
Answer:
the correct answer is D Elements
Answer: Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change
Explanation:
Answer: Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma . ... This changing of rock types is called the "Rock Cycle". Solid rock can be changed into a new rock by stresses that cause an increase in heat and pressure.
