Given the following balanced equation, determine the rate of reaction with respect to [SO3]. If the rate of O2 loss is 3.56 x 10-3 M/s, what is the rate of formation of SO3?
Answers
Answer:
7.12 × 10⁻³ M/s
Explanation:
Step 1: Write the balanced reaction
2 SO₂ + O₂ ⇒ 2 SO₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₂ to SO₃ is 1:2.
Step 3: Calculate the rate of formation of SO₃
The rate of loss of O₂ is 3.56 × 10⁻³ mol O₂/L.s. The rate of formation of SO₃ is:
3.56 × 10⁻³ mol O₂/L.s. × 2 mol SO₃/1 mol O₂ = 7.12 × 10⁻³ mol SO₃/L.s

what is the mass of 5 litres of oxygen at STP
Answers
Answer:
First and foremost, keeping in mind that at room temperature, Oxygen is a gas.
So, Volume of Oxygen(O2) given = 5.6L.
Finding moles, Moles=Volume/22.4.
Moles= 5.6/22.4=1/4moles.
So, finding mass of O2= moles × Mol. Wt.
Mass( in grams) = 1/4 × 32. We have taken 32 as oxygen is is combined state O2, so 16×2=32.
We get, mass =8 grams. This is mass not active mass.
Active mass means molarity which will be
0.25/5.6= 0.044

According to standard temperature and pressure conditions, the mass of 5 litres of oxygen is 0.157 g.
What are standard temperature and pressure conditions?Standard temperature and pressure are defined as a standard set of conditions required for experimental measurements which are established to allow comparison between different sets of data.
Standards which are commonly used are those International Union of pure and applied chemistry and national institute of standards and technology.These are not universally accepted standards but are the ones which are commonly used.
According to ideal gas equation, mass=PV×molar mass/RT= 1×22.4×16/8.314×273=0.157 g.
Thus, the mass of 5 litres of oxygen is 0.157 g.

A balloon is filled with 30.0 L of helium in the morning when the temperature is 25.00 ℃. By noon the temperature has risen to 55.00 ℃. Determine the new volume of the balloon. *
Answers
Answer:
33.0 L
Explanation:
Step 1: Given data
Initial volume of the balloon (V₁): 30.0 LInitial temperature (T₁): 25.00 °CFinal volume of the balloon (V₂): ?Final temperature (T₂): 55.00 °CStep 2: Convert the temperatures to the Kelvin scale
We will use the following expression.
K = °C + 273.15
T₁: K = 25.00°C + 273.15 = 298.15 K
T₂: K = 55.00°C + 273.15 = 328.15 K
Step 3: Calculate the final volume of the balloon
If we assume ideal behavior, we can calculate the final volume of the balloon using Charles' law.
V₁/T₁ = V₂/T₂
V₂ = V₁ × T₂/T₁
V₂ = 30.0 L × 328.15 K/298.15 K = 33.0 L

In an investigation, the volume of a material is measured
as 80.0 cm3 and its mass is measured as 253 g. Which
calculation of density correctly uses the precision rules:
3.1625 g/cm3, 3.163 g/cm3, 3.16 g/cm3, 3.2 g/cm3, or 3
g/cm3?
Answers
Answer:
3.2 g/cm3
Explanation:
Mass = 253 g
Volume = 80.0 cm3
Density = Mass / Volume = 253 g / 80.0 cm3
Density = 3.1625 g/cm3
The precision rule means the answer must not have more significant values than the value with the least number of significant figures. In this case, the value with the least number of significant figures is 80.0 with two signiificant figures. Hence;
Answer = 3.2 g/cm3

The phase transition takes place at the molecular level by changing the strength of intermolecular forces between the molecules.
What is phase change?Phase changes can be defined as the physical processes of transition between a state of a medium, identified by some parameters. These changes in states of matter that can be written as liquid, gas, solid, and plasma.
A particular phase in a thermodynamic system exhibits uniform physical properties. During a phase transition, some properties of the medium change, because of the change in external conditions, such as temperature, and pressure.
In a solid state, the molecules are compactly bound by a strong force of attraction. In the liquid state, the molecules have lesser attraction forces. The phase changes depend upon the temperature and pressure.
Therefore, phase transitions occur on a molecular level as the alteration in the strength of intermolecular forces.

what is the volume, in liters, of 5.500 mol of C3H3 gas at STP
Answers
Answer:
123.2 Liters.
Explanation:
At STP (T = 273K & P = 1atm), one mol of any gas will occupy 22.4 liters.
With the above information in mind, we can calculate how many liters would 5.500 mol of gas occupy:
5.500 mol * 22.4 L / mol = 123.2 L
So 5.500 moles of C₃H₃ would have a volume of 123.2 liters at STP.

2CO + O2 =====> 2CO2 ΔH = -566 KJ
Explanation:
A thermochemical equation is a chemical equation that includes the enthalpy change of the reaction (Lumen Learning).
In a thermochemical equation, we can easily see the heat of reaction written after the symbols of reactants and products. It tells us whether heat was evolved or gained in the chemical process. When heat is gained ΔH = positive. When heat is evolved, ΔH = negative.
The thermochemical equation for the reaction of CO and O2 is shown below;
2CO(g) + O2(g) =====> 2CO2 (g) ΔH = -566 KJ
