The reaction of nitric acid and sulfuric acid is highly exothermic so it releases a lot of heat. If the temperature is not controlled, the reaction could go into thermal runaway, which is potentially extremely hazardous.
Answer:The molecular formula of the oxide of metal be
. The balanced equation for the reaction is given by:

Explanation:
Let the molecular formula of the oxide of metal be 

Mass of metal product = 1.68 g
Moles of metal X =
1 mol of metal oxide produces 2 moles of metal X.
Then 0.03005 moles of metal X will be produced by:
of metal oxide
Mass of 0.01502 mol of metal oxide = 2.40 g (given)

y = 2.999 ≈ 3
The molecular formula of the oxide of metal be
. The balanced equation for the reaction is given by:

Answer:
<u>Kinetic particle theory</u>
Arrangement and motion of solid particles
-> Solid particles are packed closely with each other in an orderly manner. They vibrate vigorously in their fixed positions.
Arrangement and motion of liquid particles
-> Liquid particles are packed less closely with each other as compared to solid particles in a disorderly manner. They move around in a random motion; sliding past each other.
Answer:
A) SiO2 is the limiting reactant
B) Theoretical yield= 72333.3g
C) % yield =91.5%
Explanation:
SiO2(s) + 2C(s) --------------> Si(s) + 2CO(g)
n(SiO2)= 155000/60 = 2583.33 mols
n(C)= 79000/12= 3291.66 mols
a)SiO2 is the limiting reactant
According to the balanced reaction equation,
60g of SiO2 produced 28g of SiO2
155000g of SiO2 will produce 155000×28/60= 72333.3g
Therefore theoretical yield of Si= 72333.3g
% yield= 66200/72333.3×100/1 =91.5%
Answer:
396811.337 J
Explanation:
The cost of one short ton of coal = $56.45
The energy related to the short ton of coal = 
Thus, As according to the question,
$56.45 of coal have
of energy.
$1 of coal have
of energy.
<u>The amount of energy = 396811.337 J</u>
