Water is demarcated as a substance that is encompassed of the chemical fundamentals such as hydrogen as well as oxygen and prevailing in solid, gaseous, and liquid phases. It is considered one of the most plentiful and indispensable of compounds....
What Air Is Made Of Nitrogen is the most abundant gas in the atmosphere. Air is composed of 78 percent nitrogen. Oxygen accounts for 21 percent, and the inert noble gas argon makes up 0.9 percent of the air. The remaining 0.1 percent consists of several trace gases. Most of the 0.1 per...
The volume is the volume of air in the test tube minus the oxygen that the candle used. 8. To find the volume of oxygen originally in the test tube, subtract the volume of air after the candle goes out from the original volume. Record the volume in the Data Table. 9. Determine the...
What percentage of air is nitrogen gas and what percentage is oxygen gas? Why is inhaled nitrogen gas useless for our bodies? How is most of the carbon dioxide carried by the blood? A) it is bound to hemoglobin as carboxyhemoglobin B) it i...
Besides breathing, the presence of oxygen is required for combustion (that is, burning of fuels and other substances). Both respiration and combustion processes utilise oxygen and release carbon dioxide in the atmosphere. Carbon Dioxide Carbon dioxide makes up a small component of the air around us...
