What do you predict will happen to the volume inside a container when pressure & temperature remains constant but the number
Pani-rosa [81]

Answer:

<u>increase</u>

Explanation:

<u>The Ideal Gas Equation</u>

  • PV = nRT
  • V = nRT/P
  • V ∝ n

The volume of a gas is directly proportional to the number of moles it contains. Hence, if the number of particles is increased, then the volume inside the container will <u>increase</u>

A laboratory manual gave precise instructions for carrying out the reaction described by the chemical equation, C2H6O + O2 C2H4O
Alexxandr [17]
C2H6O + O2 ---> C2H4O2 + H2O

using the molar masses:-
24+ 6 + 16 g of C2H6O  produces 24 + 4 + 32 g C2H4O2    (theoretical)
 46 g produces 60g 

60 g C2H4O2 is produced from 46g C2H6O
1g      .     .................................46/60 g 
 700g     .................................    (46/60) * 700  Theoretically

But as the yield is only 7.5% 

the required amount is    ((46/60) * 700 ) / 0.075 =  7155.56 g 

=  7.156 kg to nearest gram.  Answer

Why does sugar dissolve faster than salt
Usimov [2.4K]

☁️ Answer ☁️

Option 1: When dissolved, sugar molecules have more opportunities to bond with positive-negative water molecules. Therefore, sugar dissolves faster than salt, because its component molecules are more soluble in water.

❤️

Option 2: Sugar can dissolve easier than salt because when you add 8 spoons of salt into water the salt already starts to stay in the bottom of the cup. And, when you add 30 spoons into water the sugar just starts to stay in the bottom of the cup. It’s almost the same.

Hope it helps.

Have a nice day!~  ̄▽ ̄❤️
