For this item, we need to assume that air behaves like that of an ideal gas. Ideal gases follow the ideal gas law which can be written as follow,
PV = nRT
where P is the pressure,
V is the volume,
n is the number of mols,
R is the universal gas constant, and
T is temperature
In this item, we are to determine first the number of moles, n. We derive the equation,
n = PV /RT
Substitute the given values,
n = (1 atm)(5 x 10³ L) / (0.0821 L.atm/mol.K)(0 + 273.15)
n = 223.08 mols
From the given molar mass, we calculate for the mass of air.
m = (223.08 mols)(28.98 g/mol) = 6464.9 g
<em>ANSWER: 6464.9 g</em>
C
A has 2H 2O on the left and 4H 2O on the right
B has 4H 4O on the left and 4H 2O on the right
D has 2H 2O on the left and 2H 4O on the right
C has 2H 2O and 2H 2O so is balanced.
Answer: The correct answer is e) all reactions are at equilibrium.
Explanation: In order for cellular vitality to develop, it is necessary for it to be in energetic balance with the environment, that is, to give and receive energy with the environment that surrounds it through endothermic or exothermic reactions. That is why the development of life is considered a system that constantly exchanges with the environment. In turn, that the cell unit maintains a balance with the environment causes homeostasis to occur among the whole organism.
S (s) + O₂ (g) → SO₂ (aq) represents this chemical reaction
<h3>Further explanation</h3>
In stating a chemical equation it can be done in the form of a word or a chemical formula
A word equation will include the words of the reactants, products, form of the compound (liquid, gas, solid), the total concentration/quantity of the reactants and products which can be expressed in mass, moles, or volume
The questions statement above shows that sulfur powder (S) and oxygen gas (O₂) are reactants (located on the left of the reaction equation), and sulfur dioxide (SO₂) is the product of the reaction (stated in the problem there is the word "to form") which is located on the right
So the complete reaction
S (s) + O₂ (g) → SO₂ (aq)
