Why are NaI and CH2O more soluble in water than benzene (C6H6)?
Shawbug
Sodium iodide is ionic and formaldehyde is polar. Water, being a polar molecule will readily dissolve both. Benzene is nonpolar so it will not readily dissolve polar or ionic substances.

Is CH2O an acid?
No. CH2O is formaldehyde, which is not an acid.
What is the Photosynthetic equation?
CO2 + 2H2O + photons → [CH2O] + O2 + H2O or carbon dioxide + water + light energy → carbohydrate + oxygen + water.
How much CH2O is needed to prepare 445 mL of a 2.65 M solution of CH2O?
35.38g
How many atoms of hydrogen 31 grams in CH2O?
31 grams CH2O (1 mole CH2O/30.026 grams)(2 mole H/1 mole CH2O)(6.022 X 1023/1 mole H) = 1.2 X 1024 atoms of hydrogen =======================
How many molecules of CH2O are in 50.0 g of CH2O?
Molar mass of CH2O = 12 + 2 + 16 = 30 g/mole50.0 g x 1 mole/30 g = 1.67 moles
Is CH2O not soluble in water?
yes it is becasue water is a polar molecule and therefore, can only disolve another polar molecule such as ch2o
Does the compounds C2H2 and C6H6 have the same percent composition by mass?
It does not necessarily mean that. For example glucose (C6H12O6) and formaldehyde (CH2O) have the same percentages of elements by mass, but are two very difference compounds.
Is CH2O an acid?
No. CH2O is formaldehyde, which is not an acid.
What is the characteristic of vinegar water?
the vinegar multiple units of CH2O and special arrangement
What is the formula for CH2O?
C2h4o2 is the molecular formula for CH2O.
What do empirical formulas determine?
Empirical formulas determine the ratio of atoms of different elements within a chemical compound and can be derived by dividing the number of each element's atoms by their greatest common factor. They do not necessarily describe the full chemical makeup of a molecule. For example, benzene has the formula C6H6 but its empirical formula is simply CH because there is one hydrogen atom for every carbon atom. Glucose has the molecular formula of C6H12O6; its empirical formula is CH2O. Because the molecular formula for water, H2O, cannot be further simplified (empirical formulas have only whole numbers) H20 is also its empirical formula.
What is the difference between organic and inorganic substances?
It's arbitrary (and some chemicals are classed as both);but in general organic contains carbon molecules and/or those related to life. It is the chemistry of carbon containing compounds.Inorganic is everything else and generally do not contain carbon (with some exceptions).
What is molecular formula of formalin?
A 37% aqueous (water) solution of formaldehyde. The molecular formula of water is H2O and of formaldehyde is CH2O.
Is ch2o a compounf?
Yes. CH2O is the molecular formula of formaldehyde, the smallest aldehyde.
The simplest possible formula that illustrates the proportion of elements in monosaccharides is what?
Ch2o
What is photosynthsis needed for?
Water-corbondioxide-sun= glocuse + oxygen. C2O+H2O+sun+CH2O+CO2
What is the Photosynthetic equation?
CO2 + 2H2O + photons → [CH2O] + O2 + H2O or carbon dioxide + water + light energy → carbohydrate + oxygen + water.
