Answer:
B absorption
Explanation:
because absorption is the transfer of energy carried by light waves to particles of matter
Answer:
it may be helium according to my knowledge
Answer:
the moles of N2O are 33/(14.2 + 16) = 0,75 (mol)
NH4NO3 -----------> N2O + 2H2O
0.75 <--- 0.75
=> The moles of NH4NO3 are 0,75 mol
=> m = 0,75(14.2 + 4 + 16.3) = 60 (g)
Explanation:
Answer:- -2260 kj.
Solution:- It could easily be solved using dimensional analysis. From given information, the enthalpy change for the combustion of 2.00 grams of propane is -102.5 kj. It asks to calculate the enthalpy change in same conditions for the combustion of 1 mole of propane.
We convert 1 mole of propane to grams using molar mass(44.1 gram per mol) and then calculate the heat using the given information as:
= -2260 kj
Hence, the enthalpy change for the combustion of 1 mol of propane is -2260 kj.
