Answer:
Aqueous carbonic acid (H2CO3) decomposes into a carbon dioxide gas and liquid water. Write a balanced equation for this reaction? | Socratic Aqueous carbonic acid (H2CO3) decomposes into a carbon dioxide gas and liquid water.
Explanation:
Answer:
The pressure of the gas is 13, 04 atm.
Explanation:
We use deal gas formula. First, we convert the unit of temperature in Celsius into Kelvin. We use the constant R= 0,082 l atm /K mol.Then, we solve P (pressure).
0°C=273 K 45°C= 273 + 45= 318 K
PV=nRT -----> P= (nRT)/V
P= (5 mol x 0,082 l atm /K mol x 318 K)/ 10 L
<em>P= 13,038 atm</em>

<u>Answer:</u></h3>
<u>1 mole of a gas at STP occupies 22.4 L volume </u>
<u>Now the volume is given =78.4 therefore,</u>
<u>No. of moles of gas = 78.4 ÷ 22.4 = 3.5 moles</u>

For the answer to the question above, use these formulas in solving your problem and as a guide.
<span>
MM = 342 (g/mol) </span>
<span>171 (g) / 342(g/mol) = x mol of sucrose </span>
<span>x moles of sucrose/ 1.25 L = Molarity of soultion
</span>I hope I helped you with your problem. Have a beautiful day!
D is the answer. A, B,C are absurd. Doing a little word right there.
