What is the word equation for burning ethanol?
Ethanol+oxygen-carbon dioxide+water
Are ethanol resistant markers suitable for use in laboratory settings where exposure to ethanol-based solutions is common?
Yes, ethanol resistant markers are suitable for use in laboratory settings where exposure to ethanol-based solutions is common.
What is the name of a substance formed by burning hydrogen and ethanol in air?
what is the substance formad when burning both hydrogen and ethanol in the air
Why 95 percent ethanol is used in laboratory?
95% ethanol is commonly used in laboratories because it is an effective solvent for a wide range of chemicals and biological substances. It also has antimicrobial properties, making it useful for disinfecting surfaces and equipment. Additionally, 95% ethanol is less prone to evaporation compared to absolute ethanol, providing a more stable solution for various applications.
What is the word equation for ethanol burning in air?
ethanol + oxygen ----> Carbon Dioxide + water (assume complete combustion) CH3CH2OH + 3O2 ---> 2CO2 + 3H2O *also, when a compound is burning,we chemists use the term Combustion, which refers to the exothermic reactions which occur between some fuel source and an oxidant. Thus, "Ethanol burning in air" is rather redundant :]
What is the simple way to test the purity of ethanol after distillation in fermentation?
One simple way is to measure the specific gravity of the ethanol using a hydrometer. Another method is to use a simple alcoholmeter to measure the alcohol content. You can also use a refractometer to measure the refractive index of the ethanol, which can indicate its purity.
When ethanol reacts with oxygen what product is formed?
When ethanol reacts with oxygen, carbon dioxide and water are produced. This reaction typically occurs during combustion, such as burning ethanol as fuel.
Is burned ethanol a physical or chemical change?
Burning anything (a liquid or a solid) is a chemical change and the reaction is known as a combustion reaction.
What do you get when you burn ethanol?
Burning ethanol produces carbon dioxide and water as byproducts, along with heat energy.
How is biomass related to biofuels?
Burning biomass to make ethanol and bio-diesel.
Solubility of silics gel in ethanol?
Silica gel is insoluble in ethanol and most (if not all) laboratory solvents.
Why 70 ethanol is used as disinfectant?
a) 70% ethanol has been found to b most effective in killing microbes.Higher or lower concentrations may not b as effective. b) if u use 90% or absolute ethanol, it will evaporate fast and may not be much effective. c) using higher concentrations will leave its traces on the applied surfaces d) higher concentrations of ethanol are harmful to skin and makes it dry pretty a) 70% ethanol is most effective.higher or lower ones r not as effective b) it evaporates at a slow rate than 90% or absolute ethanol. therefore it is more effective and saves ur ethanol too.. c) higher concentrations alwez leave traces applied surfaces thus addind an unwanted reagent d) 70% ethanol is comparatively less harmful to ur hands.. higher concentrations makes ur skin dry..
