Calculate the mass of water producd from the reaction of 126g of pentaboron noahydride with 192g of moleculAR OXYGEN

Sindrei [870]

Answer:

81.08g of H $_{2}$ O will be produced.

Explanation:

Write down the balanced chemical equation:

$B_5H_9 + O_2$ ⇒ $B_2O_3+H_2O$

$2B_5H_9+12O_2$ ⇒ $5B_2O_3+9H_2O$

Determine the limiting reagent:

$B_5H_9$ :- 126/63.12646 = 1.995993 mol

1.995993/2 = 0.9979965

$O_2$ :- 192/31.9988 = 6.000225 mol

6.000225/12 = 0.50001875

Therefore, $O_2$ , is the limiting reagent.

Use stoichiometry ratios to determine the number of moles of water produced:

$O_2$ : $H_2O$

12 : 9

6.000225 : 4,500168756328362

Use the mole formula to calculate the mass of water produced:

$n=\frac{m}{M} \\m=nM\\m=(4.500168756328362)(18.01528)\\m=81.08g$

The label of a gas cylinder has come off in your laboratory. You know that only one species of gas is contained in the cylinder,

soldi70 [24.7K]

Answer:

The correct option is: Oxygen

Explanation:

According to the Ideal Gas Equation: P.V = n. R.T

Here, R - ideal gas constant, P - absolute pressure, V - volume, T - temperature, n - number of moles of gas.

Also, n = given mass of gas (w) ÷ molar mass of gas (M)

Given: P = gauge pressure + barometric pressure = 1 atm + 1 atm = 2 atm; V = 5 L; w = 13 g; R = 0.08206 L·atm·mol⁻¹·K⁻¹; T = 27 °C = 27°C + 273.15 = 300.15K (∵ 0°C = 273.15 K).

Since, P.V = n. R.T = (w ÷ M) . R.T

⇒ M = (w. R.T) ÷ (P.V) = (13g × 0.08206 L·atm·mol⁻¹·K⁻¹ × 300.15K)÷(2atm × 5 L)

⇒ M = 32 g.mol⁻¹

As we know, the molar mass of oxygen gas (O₂) is 32 g.mol⁻¹.

Therefore, the gas is oxygen.

Genrish500 [490]

Salt compounds are composed of ions that form a tightly packed and ordered network, which is called a crystal lattice. It is held together by electrostatic forces known as ionic bonding. Ionic bonding refers to the chemical bond between two oppositely charged ions - a cation and an anion. This type of bond forms when there is a large electronegativity difference between two atoms.

A sample of Ar gas has a volume of 6.30 L with an unknown pressure. The gas has a volume of 8.57 L when the pressure is 2.74 atm

ExtremeBDS [4]

Answer:

3.73 atm

Explanation:

Since there is no change in temperature, we use Boyle's law.

P₁V₁ = P₂V₂ where P₁ = initial pressure of Ar gas = unknown, P₂ = final pressure of Ar gas = 2.74 atm, V₁ = initial volume of Ar gas = 6.30 L and V₂ = final volume of Ar gas = 8.57 L

P₁ = P₂V₂/V₁ = 2.74 atm × 8.57 L/6.30 L = 3.73 atm

What do you predict will happen to the volume inside a container when pressure & temperature remains constant but the number

Pani-rosa [81]

Answer:

increase

Explanation:

The Ideal Gas Equation

PV = nRT
V = nRT/P
V ∝ n

The volume of a gas is directly proportional to the number of moles it contains. Hence, if the number of particles is increased, then the volume inside the container will increase
