<u>Answer:</u>
<em>The option which is true to the knowledge is second option.
</em>
<u>Explanation:</u>
The second option tells us that the attraction between the molecules is weak and movement of particles is less. Hence it makes the state x to be liquid because in case of liquid above the given fact is true to the knowledge.
While the other options are contradicting in nature for example if it is a solid that reaction will be strong and the movement will be very weak. And in case of gas that reaction will be very weak and movement will be very strong.
Sedimentary <span>rock is formed when debris is buried, compressed and cemented together. It is formed as a result from the accumulation of sediment on landform or land mass, and then the cementation of the material. This causes the materials to permanently settle in place and turn into rocks.</span>
Answer:
Explanation:
Hello.
In this case, since the undergoing chemical reaction is only between the sodium bicarbonate and the acid HA:
For 0.561 g of yielded carbon dioxide (molar mass 44 g/mol), the following mass of sodium bicarbonate (molar mass 84 g/mol) that reacted was:
Considering the 1:1 mole ratio between CO2 and NaHCO3. Finally, the percent by mass of NaHCO3 is computed by dividing the mass of reacted NaHCO3 and t the mixture:
Best regards.
Answer:
2.0 × 10² g
Explanation:
Step 1: Write the balanced equation
2 NO₂ + 0.5 O₂ ⇒ N₂O₅
Step 2: Calculate the theoretical yield, in moles, of N₂O₅
The molar ratio of NO₂ to N₂O₅ is 2:1.
6.0 mol NO₂ × 1 mol N₂O₅/2 mol NO₂ = 3.0 mol N₂O₅
Step 3: Calculate the theoretical yield, in grams, of N₂O₅
The molar mass of N₂O₅ is 108.01 g/mol.
3.0 mol × 108.01 g/mol = 3.2 × 10² g
Step 4: Calculate the real yield, in grams, of N₂O₅
real yield = theoretical yield × percent yield
real yield = 3.2 × 10² g × 61.1% = 2.0 × 10² g
