Hemiacetals are compounds that are derived from aldehydes and ketones while acetals are compounds with a central carbon atom with 4 bonds attached to it. It must be saturated and has a tetrahedral geometry.
Balancing of chemical equation is essential because of the law of conservation of mass, which states that the mass of a system can not be created or removed.
The second equation is balanced
This is because the number of elements of each atom in the product side equal the number of elements of each atom on the reactant side.
The first equation is not balanced
This is because there is 1 molecule of on reactant side as compared to 3 molecules of
To balance the equation we add a coefficient of 3 on sulphuric acid () and a coefficient of 3 on hydrogen ()
Answer: a. 3.0 moles of water
Explanation:
According to stoichiometry,
2 moles of hydrogen combine with 1 mole of oxygen.
Thus 3 moles of hydrogen combine = moles of oxygen.
Thus hydrogen is the limiting reagent as it limits the formation of product and oxygen is the excess reagent as it is present in excess. (1.8-1.5)= 0.3 moles of oxygen will be left as such.
If 2 moles of hydrogen produce = 2 moles of water
3 moles of hydrogen will produce =moles of water.
