Enter your answer. in the provided box. Sodium borohydride (NaBH) is used industrially in many organic syntheses. One way to prepare it
is by reacting sodium hydride with gaseous diborane (B2H). Assuming an 85.0% yield, how many
grams of NaBH4 can be prepared by reacting 6.88 g of sodium hydride and 9.00 g of diborane?

What postulate of the kinetic molecular theory best explains why gases have high fluidity? because collisions between gas particles are elastic, there is no loss of energy as particles flow past each other. because gases consist of large numbers of tiny particles, they spread out and do not come in contact with each other. because the attractive forces between gas particles are negligible, gas particles can glide easily past one another. because the average kinetic energy of gas particles increases as temperature increases, gas particles behave more like a liquid. question 6 compare the compressibility of gases and liquids. support your answer by describing the arrangement of particles in gases and liquids.

Can someone me with 3 and 4 plz. this is for masteries test.
