Which two ions are present in pure water?
In pure water there is an equilibrium H2O <-> H+aq+ OH- The H+ ion is actually not free but is bound to water molecules, hence the symbol aq next to it in the equation above. For example a common species is OH3+
How many Molecules are contained in 0.900 mol O2?
There are (5.41 \times 10^{23}) molecules of (O_2) in 0.900 moles.
Is it true that an oxygen molecule has two atoms?
Yes, that is correct. An oxygen molecule consists of two oxygen atoms bonded together.
How many water molecules are removed in the synthesis of 7 triglycerides?
In the synthesis of 7 triglycerides, 6 water molecules are removed in total. Each triglyceride molecule is formed from one glycerol molecule and three fatty acid molecules, and in the process, ester bonds are formed between each glycerol and fatty acid molecule, releasing a water molecule. Therefore, for 7 triglycerides, you would have 7 × 3 = 21 fatty acid molecules and 7 × 1 = 7 glycerol molecules, resulting in the removal of 7 × 6 = 42 water molecules during ester bond formation.
What is crystallization of water?
It is basically is how many molecules are in a hydrated compound, for example CuSO4.7H2O means that for every Copper Sulphate molecules, there are 7 water molecules around it.

What is the stoichiometry answer to 2c2h6 7o2 4co2 6h2o?
The balanced equation for this combustion reaction is 2C2H6 + 7O2 -> 4CO2 + 6H2O. This means that for every 2 molecules of C2H6, we need 7 molecules of O2 to produce 4 molecules of CO2 and 6 molecules of H2O.
How many water molecules are presented in the hydrate magnesium sulfate heptahydrate?
In magnesium sulfate heptahydrate, the term "heptahydrate" means there are seven water molecules associated with each formula unit of magnesium sulfate. So, in one formula unit of magnesium sulfate heptahydrate, there are 7 water molecules.
