Answer:

4.66 L of ammonia gas will be produced

Explanation:

Step 1: Data given

The pressure of ammonia gas = 547.9 mmHg = 0.72092116 atm

Temperature = 27.6 °C = 300.75 K

Mass of ammonium sulfate produced = 8.98 gramms

Molar mass of ammonium sulfate = 132.14 g/mol

Step 2: The balanced equation

2NH3(g) + H2SO4(aq) → (NH4)2SO4(s)

Step 3: Calculate moles (NH4)2SO4

Moles (NH4)2SO4 = mass (NH4)2SO4 / molar mass

Moles (NH4)2SO4 = 8.98 grams / 132.14 g/mol

Moles (NH4)2SO4 = 0.0680 moles

Step 4: Calculate moles NH3

For 1 mol (NH4)2SO4 we need 2 moles NH3

For 0.0680 moles (NH4)2SO4 we need 2*0.0680 = 0.136 moles NH3

Step 5: Calculate volume NH4

p*V=n*R*T

V = (n*R*T)/p

⇒with V = the volume of NH3 = TO BE DETERMINED

⇒with n = the number of moles NH3 = 0.136 moles NH3

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒with T = the temperature = 300.75 K

⇒with p = the pressure of the gas = 0.72092116 atm

V = (0.136 * 0.08206 * 300.75) / 0.72092116

V = 4.66 L

4.66 L of ammonia gas will be produced

Answer:

4.65 L of NH₃ is required for the reaction

Explanation:

2NH₃(g)  +  H₂SO₄(aq)  → (NH₄)₂SO₄(s)

We determine the ammonium sulfate's moles that have been formed.

8.98 g . 1mol / 132.06 g = 0.068 moles

Now, we propose this rule of three:

1 mol of ammonium sulfate can be produced by 2 moles of ammonia

Therefore, 0.068 moles of salt were produced by (0.068 . 29) / 1 = 0.136 moles of NH₃. We apply the Ideal Gases Law, to determine the volume.

Firstly we do unit's conversions:

27.6°C +273 =  300.6 K

547.9 mmHg . 1 atm / 760 mmHg = 0.721 atm

V = ( n . R . T ) / P → (0.136 mol . 0.082 L.atm/mol.K . 300.6K) / 0.721 atm

V = 4.65 L

A solution has a pOH of 8.7 so what is the pH of the solution? Is the solution acidic, basic, or neutral?
RSB [31]
PH + pOH = 14

pH = 14 - pOH

pH = 14 - 8.7

pH = 5,3

This solution is <u>acidic</u>.

If pH<7 - acidic
If pH=7 - neutral
If pH>7 - basic

Nickel + oxygen = nickel oxide. What is the balanced redox reaction?
uranmaximum [27]

Answer:

This is an oxidation-reduction (redox) reaction:

2 Ni0 - 4 e- → 2 NiII

(oxidation)

2 O0 + 4 e- → 2 O-II

(reduction)

Ni is a reducing agent, O2 is an oxidizing agent.

A 0.4272 g sample of an element contains 2.241 x 10 ^21 atoms . what is the symbol of the element?
grin007 [14]

Answer:

Likely \rm In (indium.)

Explanation:

Number of atoms: N = 2.241 \times 10^{21}.

Dividing, N, the number of atoms by the Avogadro constant, N_A \approx 6.023 \times 10^{23} \; \rm mol^{-1}, would give the number of moles of atoms in this sample:

\begin{aligned} n &= \frac{N}{N_{A}} \\ &\approx \frac{2.241 \times 10^{21}}{6.023 \times 10^{23}\; \rm mol^{-1}} \approx 3.72 \times 10^{-3}\; \rm mol \end{aligned}.

The mass of that many atom is m = 0.4272\; \rm g. Estimate the average mass of one mole of atoms in this sample:

\begin{aligned}M &= \frac{m}{n} \\ &\approx \frac{0.4272\; \rm g}{3.72 \times 10^{-3}\; \rm mol} \approx 114.82\; \rm g \cdot mol^{-1}\end{aligned}.

The average mass of one mole of atoms of an element (114.82\; \rm g \cdot mol^{-1} in this example) is numerically equal to the average atomic mass of that element. Refer to a modern periodic table and look for the element with average atomic mass 114.82. Indium, \rm In, is the closest match.
