What element is less dense selenium or oxygen?
Oxygen is less dense than selenium. Oxygen has a density of about 1.43 grams per cubic centimeter, while selenium has a density of about 4.81 grams per cubic centimeter.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Put the gases in order from least to most dense Oxygen carbon dioxide helium?
Helium, Oxygen, Carbon Dioxide (least to most dense)
What is the number of hydrogen atoms in a molecule ethyne?
The chemical formula of ethyne (acerylene) is C2H2 - two hydrogen atoms.
What is the chemical name for acetylene?
Ethyne
Which is most dense Steel or Oxygen?
Steel is more dense than oxygen. The density of steel is about 7.87 grams per cubic centimeter, whereas the density of oxygen is about 0.0013 grams per cubic centimeter.
Why does less dense wood burn faster?
more space for air (oxygen)
What is mercury water gold and oxygen from densest to the least dense?
(most dense to least dense) gold, mercury, water, oxygen
Why do apples float and pears sink?
Pears do not float in water because the pear is more dense than the water. The pear has a high water content, therefore making it more dense. For example, apples float because they are less dense than the water.
What is the colour ethyne after combustion?
By combustion ethyne is transformed in carbon dioxide and water.
What element is less dense selenium or oxygen?
Oxygen is less dense than selenium. Oxygen has a density of about 1.43 grams per cubic centimeter, while selenium has a density of about 4.81 grams per cubic centimeter.
What is 2c2h2 5o2-4co2 2h2o?
It is the balanced equation for the combustion of acetylene (or ethyne).
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
What were the results of the experiment in which a bottle of oxygen was placed over of air?
One bottle would have more pure oxygen then the other one, since oxygen is more dense then air, and will not rise into the atmosphere or combine with air quick
Put the gases in order from least to most dense Oxygen carbon dioxide helium?
Helium, Oxygen, Carbon Dioxide (least to most dense)
Why hydrogen gas collected by upward delivery?
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
Is ethyne polar?
polar
