Explain the following observations:
(i) Generally there is an increase in density of elements from titanium (Z = 22) to copper (z =29) in the first series of transition elements.
(ii) Transition elements and their compounds are generally found to be good catalysts in chemical reactions.
Q. Define the Normality of solutions? Ans. Sometime normality is used to measure concentration. Normality (abbreviated N) is the number of gram-equivalent masses of solute in 1
hardness of borewell water is less than that of seawater
hypothesis for this lab "finding the missing mass"
factors affecting TLC in points
Laboratory preparation of ethane
The number of species participating in the slowest step of the reaction is known as molecularity of the reaction.
(i) Use valence shell electron pair repulsion theory (VSEPR) to predict the shape of the molecule comprising oxygen, nitrogen and fluorine atoms, which has the formula ONF, and whe
determine the no of atom in 4.5g of k
what is the difference between molarity and normality
Approximate the torque and power necessary to rotate the inner 20 cm diameter cylinder shown in Figure 1. SAE 10W-30 oil at 20°C fills the gap. Assume a linear velocity profile.
