Answer:
Explanation:
According to the law of definite proportions, particles in a compound combine by a defined stoichiometric ratio. This ratio is also calculated in terms of moles.
In order to find the ratio between the particles in a compound, we need to find the molar ratio of each species.
Notice that the ratio between the number of moles of zinc to the number of moles of nitrogen is:
This means if we are given 1 zinc ion, we expect to have a total of 2 nitrogen atoms. Therefore, x = 2.
Answer:
31,380 Joules
Explanation:
Given Data:
Mass = m = 100 g
Temperature 1 = = 25 °C
Temperature 2 = = 100 °C
Specific Heat Constant = c = 4.184
Change in Temp. = ΔT = 100 - 25 = 75 °C
Required:
Heat = Q = ?
Formula:
Q = mcΔT
Solution:
Q = (100)(4.184)(75)
Q = 31, 380 Joules
