How much methanol needed to make 100 ppm solution in 100ml water?
To make a 100 ppm solution of methanol in 100 mL of water, you would need 10 mg of methanol. This is because 100 ppm is equivalent to 100 mg/L, and since you have 100 mL of water, you would need 10 mg of methanol (100 mg/L x 0.1 L).
What is the Character for Proban Anti-flaming Treatment?
Proban anti-flaming fabric adopts the craft of PROBAN, which is famous on the international. This anti-flaming method has great washing durable performance, non-toxic, non-smell and no stimulation, air and water permeability , suitable wearing . it's eco friendly performance passed TESTEX certificate , and meet the OEKO-TEX STANDARD 100 requirement. It's anti-flaming performance and heat barrier property passed EN 11611（EN470-1）、EN11612（EN531）、ASTMD6413、NFPA2112、BS5852、ASTMF1506 test under the authority of SGS、TUV、BTTG. PROBAN: the theory is using polyphosphoric acid and special finishing craft to process cotton fabric, make fabric carbonized quickly faced the heat, comes out the isolated layer, the fabric will stop burning immediately, up to self-extinguish, so that it has anti-flaming property via shorten the time of after flame and smolder. The fabric being treated by anti-flaming process has the great wash durable performance, if kept in good condition, the clothing using time is longer with the anti-flaming property, generally, washing 50 times the anti-flaming index is still kept in the standard index. Advantage: great anti-flaming property, low strength damage( below 10%), non-smell, lower cost. Disadvantage: formaldehyde content＞100ppm, Proban processed fabric touched not softer than CP processing, after flaming fabric changed a lot on color. PYPOVATEX CP: HUNTSMAN's brand Pyrovatex CP New pure cotton process skill , which is Switzerland ciba fine chemical company 's patent. The theory is using anti-flaming chemical acids of having Pyrovatex CP New patent and its process skill to treat the cotton fabric, largely shorten the time of after flame and smolder, up to self-extinguish, so that having the anti-flaming property. The fabric treated by Pyrovatex CP New anti-flaming process, which having great washable performance, generally, washing 50 times the anti-flaming index is still kept in the standard index. Besides, Pyrovatex CP New processed fabric touched soft , non-smell ,and also can reach Oeko-Tex Standard 100 eco-friendly standard, it's green anti-flaming product, non-toxic to human body . the technology also reached the mix function, having the property of oil-water proof and anti-crease or other function together, produce multi-functional flame retardant fabric. Advantage: great anti-flaming property, formaldehyde content≤ 80 ppm,meet the eco-friendly requirement, touched softer, after flaming process effect color fastness little on original cloth. Disadvantage: more strength damage(15-20%), more cost relatively.
What is the maximum level of CO2 to survive on the earth?
Carbon Dioxide is a very minor part of our atmosphere... It has varied between about 0.03% and 0.04%, or about 300 to 400 parts per million, with the increase over the last 50 years being approximately 0.01%.Toxicity levels are much higher. The US OSHA recommends levels less than 0.5%, or about 10 times current levels, but the human body can tolerate with mild discomfort levels up to about 2% with mild discomfort, and long term adaptation... or about 50 times the current levels.http://en.wikipedia.org/wiki/Carbon_dioxide#ToxicityAccording to estimates, carbon dioxide levels naturally have varied by about 0.01% or 100ppm in cycles... but we are currently at the highest level in 400,000 years.See Wikipedia:http://en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's_atmosphereHowever, estimates of carbon dioxide levels in the distant past indicate that the levels may have been much higher 100 to 300 million years ago, when Dinosaurs roamed the planet. These levels would have been approximately 1000 to 2000 PPM, or the range of 1% to 2%, and perhaps even higher 400 million years ago.See the additional chart from the above Wikipedia article.This doesn't mean the consequences of such extreme increases in carbon dioxide might not be traumatic for the world as we know it.The above images were distributed by Wikipedia in the links above, and are in the Public Domain.
What would happen if we had too much greenhouse gas?
Global warming, the gases form a blanket around the earth and the heat or radiation produced by the earth cannot escape from the planet and as such the temperature rises resulting in a warmer Earth.
Write a note on global warming?
GLOBAL WARMINGMany scientists agree that the earth is warming up due to the addition of anthropogenically produced greenhouse gases (CO2, CH4, NOx) to the atmosphere. Current estimates place the expected level of global warming over the next century to be between 1.0 and 4.5 oC. Recent ocean research suggests that the higher end estimate is closer to the truth based on increased heat storage in the oceans.An increase of 3oC would make this the warmest period in the past 100,000 years, while an increase of 4oC would make the earth the warmest its been since the Eocene Epoch about 40,000,000 years ago.While the absolute degree change would not make the planet warmer than it has been in the past, the rate at which that change takes place could have major effects on species diversity. Current estimates would put the rate of change at between 15 and 40 times the rate of past natural changes.Changes in the global temperature patterns would trigger widespread alterations in the rainfall pattern, with some areas receiving a major increase in rainfall, while others experience major droughts. A long term drying trend is predicted for summers in mid-latitude interior continental regions, with up to a 40% decrease in precipitation in the US Great Plains.Increased concentrations of CO2 may accelerate the growth of some plants at the expense of others which would destabilize natural communities. Greater warming is expected to occur in higher latitudes, suggesting that temperate and arctic species would be placed in greater danger than their tropical relatives. While continued melting of the ice caps would raise sea level, flooding coastal areas.

If you do not have a chemical sanitizer how can you sanitize?
Without a chemical sanitizer, you can still effectively sanitize by using hot water above 171°F (77°C) to rinse surfaces or by utilizing a bleach solution with a concentration of at least 100ppm (1 tablespoon of bleach per gallon of water). Make sure to thoroughly rinse surfaces after using these sanitizing methods.
