Ammonium nitrate dissociates in water according to the following equation:
Viktor [21]

Answer:

Explanation:

NH₄NO₃ = NH₄⁺ +NO₃⁻

heat released  by water = msΔ T

m is mass , s is specific heat and ΔT is fall in temperature

= 50  x 4.18 x ( 22 - 16.5 )  ( mass of 50 mL is 50 g )

= 1149.5 J .

This heat will be absorbed by the reaction above .

q for the reaction = + 1149.5 J

2 )

molecular weight of NH₄NO₃ = 80

No of moles reacted = 5/80 = 1 / 16 moles.

3 )  

5 g absorbs 1149.5 J

80 g absorbs 1149.5 x 16 J

= 18392 J

= 18.392 kJ.

= + 18.392 kJ

ΔH =  18.392 kJ / mol

A soccer player applies a force of 56.6 N to a soccer ball while kicking it. If the ball has a mass of 0.46 kg, what is the acce
lubasha [3.4K]

Answer:

a=123.04\ m/s^2

Explanation:

Given that,

Force applied to a soccer player, F = 56.6 N

The mass of the ball, m = 0.46 kg

We need to find the acceleration of the soccer ball. The force acting on the ball is given by :

F = ma

Where

a is the acceleration

a=\dfrac{F}{m}\\\\a=\dfrac{56.6 }{0.46 }\\\\a=123.04\ m/s^2

So, the required solution is 123.04\ m/s^2.

Feliz [49]
Mass of Li: 6.94 g Li
Conversion relationship: 1 mole Li=6.94 g Li
100.0 g Li 1 mole Li
---------- x ---------- = 14.4 moles Li
1 6.94 g Li
Conversion relationship: 1 mole Li=6.02x10^23 atoms Li
14.4 moles Li 6.02x10^23 atoms Li
-------------- x ----------------------- = 8.67x10^24 atoms Li
1 1 mole Li
