Methane gas, which may be present in confined spaces such as a basement, can cause death by asphyxiation.

<h3>What are the dangers of methane gas in confined space?</h3>

Low amounts are safe for inhalation. A significant amount can replace oxygen in the atmosphere. Reduced oxygen availability can cause symptoms like weariness, emotional instability, fast breathing, and rapid heart rate. Insufficient oxygen can cause nausea, vomiting, collapse, convulsions, coma. The onset of symptoms is accelerated by physical activity. Organs including the heart and brain can suffer long-term damage from a lack of oxygen.

Contact with Skin: Not irritating. The skin might become chilled or frozen when in direct touch with the liquid gas (frostbite). Itching and numbness are signs of mild frostbite. Burning and rigidity are signs of more serious frostbite.

No evidence of carcinogenicity.

Use the standard free energies of formation (ΔGf°) of each substance to determine the value of equilibrium constant K at 25 °C f

Greeley [361]

Answer:

k = 8,83x10³⁹

Explanation:

For the reaction:

CO₂(g) + 2H₂(g) ⇌ CH₃OH(l)

ΔG° = ΔGproducts - ΔGreactants

ΔG° = ΔGCH₃OH(l) - (ΔGCO₂(g) + 2ΔGH₂(g)

As ΔGCH₃OH(l) = -166,4 kJ/mol; ΔGCO₂(g) = -394,4 kJ/mol; ΔGH₂(g) = 0 kJ/mol

ΔG° = -166,4 kJ/mol - (-394,4 kJ/mol + 2×0 kJ/mol)

ΔG° = 228,0 kJ/mol

The ΔG could be defined as:

ΔG = -RT lnK

Where R is gas constant (8,314472x10⁻³ kJ/molK); Temperature is 25°C, 298,15K.

Replacing:

228,0 kJ/mol = 8,314472x10⁻³ kJ/molK×298,15K ln K

91,97 = ln k

K = 8,79x10³⁹ ≈ 8,83x10³⁹

When formic acid is heated, it decomposes to hydrogen and carbon dioxide in a first-order decay: . . HCOOH(g) →CO2(g) + H2 (g) .

Marat540 [252]

We are given with the reaction HCOOH(g) →CO2(g) + H2 (g). According to Dalton's law, the total pressure of a vessel is equal to the sum of the partial pressure of the components inside it. In this case, we plot first the data ln (ratio partial pressure of HCOOH to total pressure) vs time. Partial pressure is the difference of pressure (from one point to another). In this case, the equation is ln P(HCCOH) = -0.0146t - 0.2281 where R² = 0.9923. K is equal to <span> -0.0146 s-1. When the total pressure is 291, ln P is -0.66938, thus the time is 30.23 seconds. The half life is ln(0.5)/k equal to 47.46 seconds.</span>

_Li + __F2 → _LIF<br> How do I balance this?

Semmy [17]

Answer:

2Li + F₂ → 2LiF

Explanation:

The reaction expression is given as:

Li + F₂ → LiF

We are to balance the expression. In that case, the number of atoms on both sides of the expression must be the same.

Let use a mathematical approach to solve this problem;

Assign variables a,b and c as the coefficients that will balance the expression:

aLi + bF₂ → cLiF

Conserving Li: a = c

F: 2b = c

let a = 1, c = 1 and b = $\frac{1}{2}$

Multiply through by 2;

a = 2, b = 1 and c = 2

2Li + F₂ → 2LiF

How can a change to another population could affect births and deaths in the parrot population.

forsale [732]

Answer:

read it first

Explanation:

Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow.
