Molar mass of calcium=40
numbers of mole of calcium=50/40/3=5/12
number of mole of phosphorus=(5/12)*2=5/6
mass of phosphoros=(6/5)*31=25.83g//
Answer:
Both
Explanation:
An industrial chemist most consider must consider both the income earned from production of a chemical and the cost of handling the waste materials created.
A high yield is desirable, because it maximizes income.
![\text{Atom economy} = \dfrac{\text{mass of atoms in product}}{\text{ mass of atoms in reactants}} \times 100 \, \%](https://tex.z-dn.net/?f=%5Ctext%7BAtom%20economy%7D%20%3D%20%5Cdfrac%7B%5Ctext%7Bmass%20of%20atoms%20in%20product%7D%7D%7B%5Ctext%7B%20mass%20of%20atoms%20in%20reactants%7D%7D%20%5Ctimes%20100%20%5C%2C%20%5C%25)
A high atom economy is desirable, because it minimizes the amount of waste and therefore the cost of treating it.
Answer:
Formaldehyde is highly soluble in water.
Explanation:
Formaldehyde is the simplest of the aldehydes (R−CHO) it is an organic compound which occurs naturally with the formula H−CHO. . The IUPAC name of formaldehyde is methanal.
Formaldehyde at room temperature is a colorless gas and the liquid is invisible or like white-water. Formaldehyde has an irritating and very pungent like odour. Formaldehyde is very soluble in water.
Now according to Henry's constant law (3 × 10-5 kPa·m3/mol) Formaldehyde will be very unlikely to volatilize from water.and hence, Formaldehyde is considered to be highly soluble in water.
