Answer:
The right solution is "-602.69 KJ heat".
Explanation:
According to the question,
The 100.0 g of carbon dioxide:
= 
= 
We know that 16 moles of 
formation associates with -11018 kJ of heat, then
0.8747 moles formation associates with,
= 
= 
= 
Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?
Solving:
Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT
If: ΔT (T final - T initial) = ?
Answer:
According to the definitions given, atomic mass which is also called atomic weight is the measured total mass of an element's atom. Whereas, atomic number is nothing but the total number of neutrons and protons in the nucleus of an atom....
can u talk to in comment section
Water vapor
Its still water(H2O)
Just in the gas form
Answer:
<h2>0.14 kg</h2>
Explanation:
The mass of the ball can be found by using the formula
v is the velocity
k is the kinetic energy
From the question we have
We have the final answer as
<h3>0.14 kg</h3>
