Answer:
I am a grade six student but I am very interested in chemistry
Explanation:
I sorry but this is NOT chemistry
A closed system is completely closed to the outside environment. Every interaction is transmitted inside that closed system.
4/325 = 2/unknown temperature
unknown temperature= 2/(4/325)=162.5k
Answer:
H2SO4 + Al(OH)3 = Al2(SO4)3 + H2O
Explanation:
Answer: On heating, Magnesium forms its oxide; while potassium manganate(VII) decomposes
Explanation:
Magnesium Mg, on heating forms Magnesium oxide
2Mg(s) + O2(g) --> 2MgO
Potassium permanganate KMnO4, on heating decomposes to potassium manganate K2MnO4, manganese dioxide MnO2, and Oxygen gas O2.
2KMnO4 --> K2MnO4 + MnO2 + O2
The difference in observation is that, on heating, Magnesium forms its OXIDE as product; while potassium manganate(VII) decomposes, giving OFF most of its constituents and reducing its weight.
