mass * temp change * specific heat
make sure the specific heat value is in Joules
I looked it up. The amplitude of a wave is a measure of the displacement of the wave from its resting position.
Answer: Please see explanation column for answer.
Explanation: For A two-component mixture containing 1-octene and 1, 4-dimethylbenzene with acetone.
Error----- The retention factor (Rf) is 0.95 and the two spots are coming simultaneously together producing only one spot indicating that that the choice of solvent we have used is too polar. The compounds are interacting rapidly with the very polar solvent and have very low interaction with the stationary phase. than the mobile phase.
Solution:-----, We will need to try other low polar solvent that can allow two spots to be formed on the TLC plate eg is the use of different percentage s of hexane in ethyl acetate ether 10% or 20%.
Answer:
Explanation:
(a) Balanced equation
3ZnCO₃ + 2H₃PO₄ ⟶ Zn₃(PO₄)₂ + 3H₂O + 3CO₂
(b). Calculation
You want to convert moles of Zn₃(PO₄)₂ to moles of ZnCO₃
The molar ratio is 1 mol Zn₃(PO₄)₂:3 mol ZnCO₃
You need 
to form 3.0 mol of Zn₃(PO₄)₂.
