A gas sample is held at constant pressure. The gas occupies 2.97 L of volume when the temperature is 21.6°C. Determine the tempe
STALIN [3.7K]

Answer:

339.2K

Explanation:

Using Charles law equation;

V1/T1 = V2/T2

Where;

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question,

V1 = 2.97 L

V2 = 3.42 L

T1 = 21.6°C = 21.6 + 273 = 294.6K

T2 = ?

Using V1/T1 = V2/T2

2.97/294.6 = 3.42/T2

Cross multiply

2.97 × T2 = 294.6 × 3.42

2.97T2 = 1007.532

T2 = 1007.532 ÷ 2.97

T2 = 339.236

The final temperature is 339.2K

Svetach [21]

Answer: Carbonic acid occurs naturally in the body and performs important regulatory functions.

Explanation: Carbonic acid ( H_2CO_3 ) is an acid formed from the carbon dioxide present in the body. It is also known as the respiratory acid as it helps in the transport of carbon dioxide in the body.

With the help of enzyme Carbonic Anhydrase, carbon dioxide is converted into carbonic acid. This acid is an unstable intermediate which gets dissociated into bicarbonate ions ( HCO_3^- ) and H^+ ions. immediatley.

Therefore, Carbonic acid performs important regulatory functions in the body.
