Answer:
The heat of reaction is basically the energy that is being released and or absorbed when chemicals are transformed in a type of chemical reaction. However, the heat of reaction or also called reaction enthalpy is mostly or typically expressed as a molar enthalpy in kJ/mol and or as just a specific enthalpy in kJ/kg or kJ/L.
Question:
Ammonium perchlorate NH₄ClO₄ is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen N₂ gas, chlorine Cl₂ gas, oxygen O₂ gas and water vapor, releasing a great deal of energy. Calculate the moles of water produced by the reaction of 2.5 mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
Answer:
The number of moles of water produced by the reaction of 2.5 mol of ammonium perchlorate is 5 moles (of H₂O).
Explanation:
To solve the question, we are required to know the amount of each reagent and products there are in the balanced chemical reaction as follows
2 NH₄ClO₄ → N₂ + Cl₂ + 2O₂ + 4H₂O
From the chemical reaction stoichiometry, it shows that 2 moles of ammonium perchlorate, NH₄ClO₄ produces 4 moles of H₂O
Therefore 2.5 moles of ammonium perchlorate will produce
moles of H₂O or 5 moles of H₂O.
Answer: sound can slow down, so when it travels through all of that it's muffled and kind of blocked. sound travels at 332 metres per second so it's hard to stop the sound
Explanation:
Answer:
Unicellular organisms achieve locomotion using cilia and flagella. By creating currents in the surrounding environment, cilia and flagella can move the cell in one direction or another.
Explanation:
Answer:
The answer to your question is:
Explanation:
1) Data
mass = 10 g
vol = 20 ml
density = 10/ 20
= 0.5 g/ml
2)
Data
mass = 5 g
density = 2 g/ml
volume = mass / density
= 5 g / 2
= 2.5 g / ml
3)
Data
density = 25 g/ml
volume = 100 ml
mass = 25 x 100
= 2500 g
