The reaction of nh3 and o2 forms no and water. the no can be used to convert p4 to p4o6, forming n2 in the process. the p4o6 can be treated with water to form h3po3, which forms ph3 and h3po4 when heated. part a find the mass of ph3 that forms from the reaction of 1.10 g nh3.

When the mercury level in a barometer decreases that atmospheric pressure has

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.

An unknown substance has been shown to have weak covalent bonds. which of the following is most likely a property of this substance? a. high ph b. high conductivity c. low melting point d. low flammability
