nexus9112 [7]3 years ago
8 0

Answer: El HEXAHIDRATO DE SULFATO DE NÍQUEL es incompatible con ácidos fuertes, azufre, Ni (NO3) 2, madera y otros combustibles. (NTP, 1992) A temperatura elevada sufre una reacción violenta con aluminio o magnesio en polvo. Cuando se calienta hasta la descomposición emite humos muy tóxicos de óxidos de azufre

The table shows a chemical equation and the dimensional analysis used by a student to calculate the number of moles of Ba3N2 req
UNO [17]

This problem is providing the chemical reaction whereby barium nitride reacts with water to produce barium hydroxide and ammonia, so the number of moles of barium nitride are required in order to produce 8.3 moles of ammonia. It asks for us to evaluate the student's setup, so we conclude the answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3", according to:

<h3>Mole ratios:</h3>

In chemistry, stoichiometric calculations are used to figure out the moles or mass of a substance, given information about another one in the reaction. In this case, for the given chemical equation:

Ba_3N_2 + 6H_2O \rightarrow 3Ba(OH)_2 + 2NH_3

We evidence a 1:2 mole ratio of barium nitride to ammonia, for that reason, the student's setup:

8.3 mol NH_3 * \frac{1 mol Ba_3N_2 }{1 mol NH_3}

Is incorrect, because the ammonia must be accompanied by a 2 rather than the 1 it is given there:

8.3 mol NH_3 * \frac{1 mol Ba_3N_2 }{2mol NH_3}

Thereby, the correct answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3"

The 3rd answer down.

Na²O (sodium oxide) will be a base when exposed to water H²O

Explanation:

Sodium Oxide Na²O, will become Sodium Hydroxide after being exposed to water (at 80% I believe).

The oxygen ion in Na²O has 2 extra electrons which makes it highly charged and very attractive to hydrogen ions. The attraction is so strong that when Na²O comes in contact with H²O, the O(-2) strips off a hydrogen from water, forming 2 x OH ions which of course are still strongly basic.
