Answer : The enthalpy change is, 7.205 KJ
Solution :
The conversions involved in this process are :
Now we have to calculate the enthalpy change.
where,
= enthalpy change = ?
m = mass of water = 10 g
= specific heat of solid water = 2.09 J/gk
= specific heat of liquid water = 4.18 J/gk
n = number of moles of water =
= enthalpy change for fusion = 6.01 KJ/mole = 6010 J/mole
Now put all the given values in the above expression, we get
(1 KJ = 1000 J)
Therefore, the enthalpy change is, 7.205 KJ
There are fewer oxygen atoms in the equation than hydrogen or carbon. Only the oxygen needs to be balanced. There are equal numbers of hydrogen and carbon.
Answer:
NaCl
Explanation:
none of them. Salt presents NaCl
Total mass stays the same
B
Answer:
Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size. Gas particles are in constant rapid motion in random directions. Collisions between gas particles and between particles and the container walls are elastic collisions.
