From molecular mass determinations, the compounds seem to retain their dimeric nature in benzene, the NMR patterns being nevertheless more simple than expected from the crystal structures and indicate a dynamic behavior in solution. None of these compounds, so far, shows lithium motion in the solid...
An unknown compound is known to contain 30.34%M and 60.56%O and has a molar mass of 92.00 g. What are the empirical formula and the molecular formula for the compoundList three types of solids based on the nature of the bonding forces, and give ...
40. A general formula for\(x_1\)should be 1/d, which leads to\(\Delta {\mathfrak {t}} \sim N^{1/d} \Delta {\mathfrak {t}}_0\).

If the mass of the hydride was 0.0861 g, what is its molecular mass? What is the molecular formula for the hydride? Suppose you discovered a diamond completely encased in a silicate rock. How would you chemically free the diamond without harming it?
We present the simplest possible formula for the propagator of the general time-dependent quadratic Hamiltonian, including linear terms. The method is based on the use of a linear time-dependent invariant and requires only the solution of a linear homogeneous second-order ordinary differential equation...
