What is the law of multiple proportions explain with example?
Law of Multiple proportion states that when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers. For example, let us assume 2 molecules CO (carbon monoxide) and CO2(carbon dioxide).
What is the difference between the law of definite proportions and the law of multiple proportions?
The law of multiple proportions is a rule of stoichiometry. 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.
What are the laws of definite and multiple proportions and why are they important?
where c1 and c2 are real constants. This is because Law of Definite Proportions states that “a chemical compound always contains exactly the same proportion of elements by mass”. Since a real constant can always be expressed as the ratio of two whole numbers, this gave us the Law of Multiple Proportions.
How do you measure CO in air?
First, precisely measure the levels of CO in the indoor atmosphere, using the pocket size Fluke CO-220 Carbon Monoxide Meter or the multifunction Fluke 975 AirMeter™. If excess CO is detected, find and fix the problem – which is often one or more shortcomings in the HVAC system. Then test again, to verify the solution.
What is a normal reading for carbon monoxide?
Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher.
What is a CO measurement?
A carbon monoxide (CO) alarm is a time-weighted alarm. The way a time-weighted alarm works is by measuring the buildup of carbon monoxide in a house. Levels of carbon monoxide exposure range from low to dangerous: Low level: 50 PPM and less. Mid level: Between 51 PPM and 100 PPM.
What is normal CO level in blood?
These are the normal ranges for CO levels in the blood: Adults (nonsmokers): less than 2.3%, or 0.023. Adult smokers: 2.1% to 4.2%, or 0.021 to 0.042. Adult heavy smokers (more than 2 packs a day): 8% to 9%
