What is the reaction of KmNO4 with formaldehyde?
The formula of formaldehyde is CH2O. The products formed are sodium formate (HCOONa) and methanol (CH3OH). The stoichiometric equation is then X CH2O + Y NaOH --> A HCOONa + B CH3OH. Balancing the equation makes the coefficients 2 CH2O + NaOH --> HCOONa + CH3OH.
What is methonal?
Methanal, more commonly known as formaldehyde, is an organic compound with the formula CH2O. It was used for years to preserve deceased biological specimens before it was deiscovered to be carcinogenic.
What type of compounds end in -ol?
-ol is the suffix used in IUPAC nomenclature to indicate an alcohol group, -OH. The systematic name for alcohols is alkanols. Examples are methanol, CH3OH, ethanol C2H5OH and phenol, C6H5OH. All the numbers should be subscripts.
In which 1.0-gram sample are the particles arranged in a crystal structure (1) CaCl2(s) (2) C2H6(g) (3) CH3OH( and 8467) (4) CaI2(aq)?
It is solid calcium chloride. Gases, liquids and solutions have randomly arranged particles.
Chemical makeup of alcohol?
Alcohols consist of Hydroxyl group, -OH and Alkyl or hydrocarbon chain. for example alcohol C1 : CH3OH methyl alcohol alcohol C2 : C2H5OH ethyl alcohol C3 propyl C4 butyl C5 pen C6 hex ... so on
What is the concentration (M) of CH3OH in a solution prepared by dissolving 11.7 g of CH3OH in sufficient water to give exactly 100. mL of solution?
The concentration of ethanol is 11,7 %.
What is the total molar concentration of ions in a 1.240 M solution of CH3OH?
CH3OH does not ionize because it is insoluble in water
What is the molar concentration of a solution containing 22.0 g of CH3OH in 250ML?
--> number of moles of CH3OH = mass/molar mass 22/(12+3+16+1) = 0.6875 moles --> number of mole = conc multiply by volume(indm3) number of moles divided by volume[indm3] = concentration 0.6875/[.25] = 2.75 mol/dm3
Which is the better conductor CH3OH or KOH?
A solution of potassium hydroxide is a better conductor.
How many grams of ch3oh must be added to water to prepare 150 ml of a solution that is 2.0 m ch3oh?
The answer is 9.6 grams.
How many grams of CH3OH is needed to make 0.211m solution in 479g of water?
The answer is 3,211 g.
How many grams of CH3OH must be added to water to prepare 150 mL of a solution that is 1.5 M CH3OH?
7,207 g methanol are needed.
How much methonal is needed to lower freezing point of fresh water?
Methonal does not exist. Methanol (CH3OH) or methanal (CH2O) do exist, which one do you mean.
How do you get sodium methoxide from sodium hydroxide and methanol?
NaOH + CH3OH --> CH3ONa + H2O Evaporate the solution to dryness, add more CH3OH and evaporate to dryness. you can repeat a few times to ensure the remaining solid is sodium methoxide
What is the mass in grams of 9.32x1024 molecules of methanol CH3OH?
9.32*1024 (molec's CH3OH) / 6.022*1023 (molec's.mol−1 CH3OH) * 32.04 (g mol−1 CH3OH) = 495.8 g = 496 g CH3OH
Is CH3OH ionic or molecular?
CH3OH is molecular.
What is the mass in grams of 9.03 X 1024 molecules of methanol CH3OH?
9.32*1024 (molec's CH3OH) / 6.022*1023 (molec's.mol−1 CH3OH) * 32.04 (g mol−1 CH3OH) = 495.8 g = 496 g CH3OH
