Element M is prepared industrially by a two-step procedure according to the following (unbalanced) equations: (1) M. Og (s) + C(s) + Cl(9)-MCl (L) + CO(g)
(2) MCle (1) + H2 (g) ›M (s) + HCI(9)
Assume that 1.28 g of My O3 is submitted to the reaction sequence. When the HC1 produced in step (2) is dissolved in
water and titrated with 0.511 M NaOH, 216 mL of the NaOH solution is required to neutralize the HCl.
What is the atomic weight of element M?

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:

One similarity and one difference between an element and a mixture of elements

If a simple machine aduces the strength of a force, what must be increased? the speed of the input force the work the simple machine performs the size of the simple machine the distance over which the force is applied
