HE please this is very important Two positively charged particles are 0.03 m apart. The first
particle has a charge of 8.1 C, and the second a charge of 2.6C.
Which change would lead to the smallest increase in the
electric force between the two particles?
A. Reduce the charge on the first particle by one half.
B. Double the distance between the particles.
C. Double the charge on the second particle.
D. Reduce the distance between the particles by one
half

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:
