A mixture of gases contains 0.25 mol oxygen gas 0.75 mol nitrogen gas and 1.50 mol carbon dioxide gas at STP The mole fraction of oxygen gas in this mixture is?
0.1 NOPE! the one above is wrong! the answer is 0.3 (I just took it on apex:] )
The atmosphere is a mixture of?
The Earth's atmoshpere is a mixture of many gases, including nitrogen, oxygen, carbon dioxide, and hydrogen.
Which mixture of gases is thought to have made up Earth?
nitrogen (N), oxygen (O), carbon dioxide (CO2)
Is solid silicon dioxide a compound or a homogeneous mixture?
Solid silicon dioxide is not considered a compound or homogeneous mixture. It is considered a heterogeneous mixture because it contains traces of visible components that can be separated physically.
What is the difference between nitrogen oxide and nitrogen dioxide?
No. Nitrogen dioxide is a compound of nitrogen an oxygen, meaning that the two elements are chemical bonded together to form a different chemical with its own unique set of properties. In a mixture the nitrogen and oxygen would not be bonded to each other and would retain their individual properties.
Is nitrogen dioxide a mixture?
No. Nitrogen dioxide is a compound.
Is air in a bottle a compound?
Air is a mixture of various gases, chiefly nitrogen, oxygen and carbon dioxide. The last is a compound.
Is Nitrogen dioxide element mixture or compound?
Nitrogen dioxide in a COMPOUNDm because it is a chemical combination of nitrogen and oxygen. (NO2)

0.3
A tank contains a mixture of 20kg of nitrogen and 20kg of carbon dioxide The total tank volume is 20 cubic meter Determine the density and specific volume of the mixture?
the answer is 34 nan 6789
Air is composed of nitrogen, oxygen, argon, carbon dioxide, and other gasses How may air be best described?
Air contains all of these gasses as a mixture. Carbon dioxide is a chemical compound (molecule) Carbon (C) and Oxygen (O2)
Is air mixture compound element?
Air is a mixture, even though the there is a nearly constant ratio between its two principal constituents, which are nitrogen and oxygen. To qualify as a compound, a substance must have ratios among all its elements that are as nearly constant as the precision of knowledge about atomic weights permits, and air does not qualify because it contains varying amounts of water vapor, among other variations in its minor constituents.
Is air compound or Mixture?
mixture
Is air also called carbon dioxide?
no air is a mixture of gases such as nitrogen carbon dioxide oxygen etc.
The atmosphere is a mixture of?
The Earth's atmoshpere is a mixture of many gases, including nitrogen, oxygen, carbon dioxide, and hydrogen.
Is oxygen a mixture or a compound?
Neither. Oxygen is an element. In the air it forms a mixture with nitrogen, carbon dioxide, etc.
