Answer:
Decomposition or cracking
Explanation:
Decomposition reaction is a chemical change in which a single compound is broken down into two or more simpler products.
For example;
A → B + C
The driving force of such reaction is the high positive heat of formation of the compound which indicates that they are highly unstable.
Some stable compounds also decompose when subjected to high temperature and pressure.
Answer:
Heyy Mason, I donʻt know if you got the answer already but I was also trying to find the answer haha and came across this. Might as well help you since I eventually stopped being lazy and did the calculations...The answer is 144 L.
Explanation:
Use Charles Law to solve this
V1 = 50.0L
T1 = 205K
V2 = ?
T2 = 590K
using V1/T1 = V2/T2 plug in the numbers
50.0L/205K = V2/590K
Switch it around so V2 is isolated
V2 = 590K(50.0L/205K)
cancel out the K
solve
you get 143.90243
round to 144
They attract each other to form ionic networks.
Answer:
ΔH = -601.9 kJ/ mol Mg
Explanation:
Step 1: Data given
Mass of the solid magnesium sample = 0.2475 grams
The heat capacity of calorimeter = 3024 J/°C
The temperature increases by 2.027 °C
Step 2: Calculate the heat transfer
q = Ccal * ΔT
⇒with q = the heat transfer
⇒with Ccal = the heat capacity of calorimete 3024 J/°C
⇒ΔT = The temperature increases by 2.027 °C
q = 3024 J/°C * 2.027 °C
q = 6129.6 J
Since this is an exothermic reaction, ΔH will be negative
Step 3:Calculate the heat associated with the burning of Mg
Heat = -6129.6 J / 0.2475 grams Mg
Heat = 24766 J/grams = -24.77 kJ /grams Mg
Heat = -24.77 kJ/ grams * 24.3 g/mol
ΔH = -601.9 kJ/ mol Mg
