If a gas in a balloon occupies 2.25 L at 298 K and 300 kPa, the temperature at which the balloon expand to 3.50L and 2.17 atm is 345.23K.
<h3>How to calculate temperature?</h3>
The temperature of an ideal gas can be calculated using the following formula:
P1V1/T1 = P2V2/T2
Where;
- P1 = initial pressure
- P2 = final pressure
- V1 = initial volume
- V2 = final volume
- T1 = initial temperature
- T2 = final temperature
According to the information given in this question;
- P1 = 300kpa = 2.96 atm
- P2 = 2.17 atm
- V1 = 2.25L
- V2 = 3.50L
- T1 = 298K
- T2 = ?
2.96 × 2.25/298 = 2.17 × 3.5/T2
0.022T2 = 7.595
T2 = 7.595 ÷ 0.022
T2 = 345.23K
Therefore, if a gas in a balloon occupies 2.25 L at 298 K and 300 kPa. the temperature at which the balloon expand to 3.50L and 2.17 atm is 345.23K.

Please note that C = speed of light, ν = frequency, λ= wavelength, h = Planck's Constant
Answer:
A: plants give off water vapor as a waste product as they process energy
Explanation:
Evapotranspiration in plants is defined as the process whereby water is evaporated from its leaves through transpiration during the process of photosynthesis. Different factors like wind, humidity, temperature and availability of water could make it vary.
Comparing all the options, to this definition, the correct answer is Option A.
The Balanced Reaction is 2N₂O₃⁻ -----> 2 N₂ + 3 0₂
<h3>What is a Balanced Reaction ?</h3>
A reaction in which the number of atoms of each element in the reactant and the product are equal is called a Balanced Reaction .
It is given in the question:
To Balance the chemical equation.
N₂O₃⁻ -----> N₂ + 0₂
To balance the reaction , the number of molecules of each element , i.e. Nitrogen (N) and Oxygen (O) needs to be balanced
