Answer:
8 × 10³ mol N₂
Explanation:
Step 1: Write the balanced equation
2 C₃H₅N₃O₉ ⇒ 6 CO₂ + 5 H₂O + 0.5 O₂ + 3 N₂
Step 2: Convert the mass of C₃H₅N₃O₉ from tons to grams
We will use the conversion factor 1 t = 907185 g.
1.320 t × 907185 g/1 t = 1.197 × 10⁶ g
Step 3: Calculate the moles corresponding to 1.197 × 10⁶ g of C₃H₅N₃O₉
The molar mass of C₃H₅N₃O₉ is 227 g/mol.
1.197 × 10⁶ g × 1 mol/227 g = 5.27 × 10³ mol
Step 4: Calculate the moles of N₂ formed from 5.27 × 10³ moles of C₃H₅N₃O₉
The molar ratio of C₃H₅N₃O₉ to N₂ is 2:3.
5.27 × 10³ mol C₃H₅N₃O₉ × 3 mol N₂/2 mol C₃H₅N₃O₉ = 7.91 × 10³ mol N₂ ≈ 8 × 10³ mol N₂
D removing thermal energy from the water
Event 1 is an example of a chemical reaction.
<u>Explanation:</u>
Whenever there is a chemical reaction, we can find that by means of a color change, formation of any gas, vapors, bubbles or any color or colorless precipitation, or by means of heat generation.
In the event 1 there is only a clear liquid in the beaker again it is added to a clear liquid in another beaker, forming an orange colored liquid , which shows that there is an occurrence of some chemical reaction.
So Event 1 is most likely an example of a chemical reaction.
The answer is: Ammonium hydroxide would be found in the pantry because it is found in vinegar.
Ammonim hydroxide (NH₄OH) is base and vinegar is acid.
pH of ammonium hydroxide is greater than 7 and vinegar has pH less than 7.
Ammonium hydroxide is a smelling, colorless liquid.
It is used as cleaning product, disinfectants and stain treaters.
Household ammonia contains 5-10% ammonium hydroxide.
Answer:
The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity. However, mass and velocity are indirectly related.
