Answer : The volume of the balloon will be, 0.494 liters
Solution :
Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
= initial volume of gas = ?
= final volume of gas = 0.54 L
= initial temperature of gas = 273.15 K
= final temperature of gas = 298.5 K
Now put all the given values in the above equation, we get the initial volume of balloon.
Therefore, the volume of the balloon will be, 0.494 liters
Since it's C2, then it must be two Carbon atoms. Think of it this way; there are two atoms of Hydrogen in a water molecule, so we now have H2O.
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. ... is the heat added to, or removed from, the system.
Answer:
D
Explanation:
--2 K (s) + __ H2SO3 (aq) --
-->
_K2SO3 (aq) + __H2
To balance this equation, all you need do is put a 2 in front of the K. The rest don't require any balancing coefficients.
Left
2 K
2 H
1 SO3
Right
K2
1 SO3
1 H2
It's balanced.
