Density = mass/volume
D = 500 g /200 cm^3
D = 2.5 g/cm^3
hope this helps!
The mass of nitroglycerin : 34.52 g
<h3>Further explanation</h3>
Reaction
4C₃H₅N₃O₉ ⇒ 12 CO₂ + 10H₂O + 6N₂ +O₂
Volume = 10 L
Temperature = -5°C=268 °K
Pressure = 1 atm
mol of CO₂ (ideal gas) :
mol ratio C₃H₅N₃O₉ : mol CO₂= 4 : 12, so mol C₃H₅N₃O₉ :
mass C₃H₅N₃O₉ (MW=227,0865 g/mol):
Answer:
the positively charged particle found in atomic nuclel
Explanation:
protons carry positive charge and attracts negatively charged particles called electron
Answer:
O2(g) was Reduced
Explanation:
It is necessary at this point to restate the working definitions of oxidation and reduction.
Oxidation refers to increase in oxidation number. A chemical specie is oxidized in a chemical reaction if there is a positive increase in its oxidation number from left to right in the reaction.
A chemical specie is said to be reduced when there is a decrease in its oxidation number from left to right in a reaction. Hence reduction refers to a decrease in oxidation number.
Now let us focus on O2(g). Its oxidation number on the left hand side is zero. On the right hand side, its oxidation number decreases to -2. This shows a decrease in oxidation number. From our premises above, we can safely conclude that O2(g) was reduced in the reaction.
The statement that is correct concerning Hess's law is D. Hess' Law of Constant Heat Summation expresses that paying little respect to the numerous stages or ventures of a response, the aggregate enthalpy change for the response is the whole of all progressions. This law is an indication that enthalpy is a state work.
