According to the following reaction, how many grams of hydrogen

Mila [183]

Answer:

7.03 g

Explanation:

Step 1: Write the balanced synthesis reaction

N₂(g) + 3 H₂(g) ⇒ 2 NH₃(g)

Step 2: Calculate the moles corresponding to 32.5 g of N₂

The molar mass of N₂ is 28.01 g/mol.

32.5 g × 1 mol/28.01 g = 1.16 mol

Step 3: Calculate the number of moles of H₂ needed to react with 1.16 moles of N₂

The molar ratio of N₂ to H₂ is 1:3. The moles of H₂ needed are 3/1 × 1.16 mol = 3.48 mol.

Step 4: Calculate the mass corresponding to 3.48 moles of H₂

The molar mass of H₂ is 2.02 g/mol.

3.48 mol × 2.02 g/mol = 7.03 g

What is the new pressure if the temperature outside is 296k and his weight causes the tire's volume to drop to 2.0 liters

sukhopar [10]

Question:

At standard temperature and pressure, the volume of a tire is 3.5L. What is the new pressure if the temperature outside is 296k and its weight causes the volume of the gas is 2.0 L?

Answer:

The new pressure is: 1.896 atm

Explanation:

At standard temperature and pressure, we have:

$P_1 = 1atm$

$T_1 = 273.15k$

$V_1 = 3.5L$

Outside, we have:

$T_2 = 296k$

$V_2 = 2.0L$

Required

Determine the new pressure

Using combined gas law, we have:

$\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}$

This gives:

$\frac{1 * 3.5}{273.15} =\frac{P_2*2.0}{296}$

Solve for $P_2$

$P_2 = \frac{296 * 1 * 3.5}{273.15*2.0}$

$P_2 = \frac{1036}{546.30}$

$P_2 \approx 1.896 atm$
