9.0 l of o2 react with excess co at stp. how many moles of co2 form during the reaction?2CO(g)+O2(g)→2CO2(g)
Answers
The chemical equation for the interaction of CO and O2 to produce CO2 is as follows:
O2(g) + 2CO(g) 2CO2 (g)
According to the equation, 2 moles of CO and 1 mole of O2 combine to generate 2 moles of CO2. In order to determine how many moles of CO2 were produced, we must first determine how many moles of O2 were involved in the process.
1 mole of any gas takes up 22.4 L of space at STP (Standard Temperature and Pressure). As a result, 9.0 L of oxygen at STP is:
9.0 L/22.4 L/mol equals 0.402 moles of oxygen
We can determine how many moles of CO2 were produced since 1 mole of O2 combines with 2 moles of CO to make 2 moles of CO2.

Answer:
- Anode: Co3+ | Co2+
- Cathode: Ni | Ni2+
Explanation:
The anode is where oxidation reaction occurs, and the cathode is where reduction reaction occurs.
From the table of reduction potencials, we find that:
- Co reaction:
\(\begin{gathered} Co^{3+}+2e^-\rightarrow Co^{2+} \\ E=1.81\text{ }V \end{gathered}\)- Ni reaction:
\(\begin{gathered} Ni\rightarrow Ni^{2+}+2e^- \\ E=-0.250\text{ V} \end{gathered}\)Now, to find out which one is the anode and which one is the cathode, it is necessary to compare the reduction potencials.
The reaction of Ni have negative potentials, so Ni will be the anode and Co will be the cathode.

The adiabatic flame temperature in Kelvin is,

5050

Answers
The adiabatic flame temperature is 298.15k. In a combustor, carbon monoxide (CO) reacts with gaseous oxygen (0₂) to produce carbon dioxide (CO₂).
The process is adiabatic, meaning there is no heat exchange with the surroundings. The reactants enter the combustor at 25°C and 100 kPa, and the products exit at an unknown temperature called the adiabatic flame temperature. The pressure of the outgoing CO₂ is 100 kPa. We need to calculate the adiabatic flame temperature in Kelvin.
To calculate the adiabatic flame temperature, we can use the principle of adiabatic combustion and the First Law of Thermodynamics, which states that the change in internal energy of a system is equal to the heat added minus the work done by the system.
In this case, since the combustor is adiabatic, there is no heat exchange with the surroundings, so the heat added is zero. Therefore, the change in internal energy is solely due to the work done by the system.
The work done by the system is equal to the pressure-volume work, which can be expressed as:
Work = P * (V_final - V_initial)
Since the combustor is operating at steady state, the volume remains constant, so the work done is also zero. This means that the change in internal energy is zero.
Since the change in internal energy is zero, the adiabatic flame temperature is the same as the initial temperature of the reactants, which is 25°C. Converting this to Kelvin, we have:
Adiabatic flame temperature = 25°C + 273.15 = 298.15 K
Therefore, the adiabatic flame temperature is 298.15 K.

Sodium chloride is NaCl, and zinc chloride ZnCl₂. Why are there more chloride ions in the zinc compound?
Answers
Answer:
Zinc chloride (ZnCl2) has more chloride ions compared to sodium chloride (NaCl) because the zinc ion has a +2 charge, while the sodium ion has a +1 charge.
Chlorine (Cl) is a halogen element with a -1 charge when it gains an electron to form an ion. To form a neutral compound, the number of positive and negative charges must be balanced.
In NaCl, the sodium ion has a +1 charge and can only bond with one negatively charged chloride ion, which has a -1 charge. Therefore, the formula for sodium chloride is NaCl, with one sodium ion and one chloride ion.
In ZnCl2, the zinc ion has a +2 charge, and it requires two negatively charged chloride ions, each with a -1 charge, to form a neutral compound. Therefore, the formula for zinc chloride is ZnCl2, with one zinc ion and two chloride ions.
Thus, the reason why there are more chloride ions in the zinc compound is because the zinc ion has a higher charge compared to the sodium ion, and it requires two chloride ions to balance its charge, whereas sodium ion requires only one chloride ion.

What is chemical equilibrium?
This is simply defined as a state in a chemical system where there is no observable change in the properties of the system with time.
Principle of chemical equilibriumA French scientist postulated a principle which helps us to understand a chemical system in equilibrium.
The principle states as follow:
If a an external constraint such as change in temperature, pressure or concentration is imposed on a system in equilibrium, the equilibrium will shift so as to neutralize the effect.
How to determine what will happen if the volume of the container is increased from 2 L to 4 LFrom the principle given above, we can see that volume does not affect equilirium position.
However, from Boyle's law, we understood that pressure and volume are in invest relationship.
Thus, increasing volume simply means decreasing pressure.
A decrease in pressure will favors the side where there is an increase in volume.
Let us consider the equation from the question:
N₂(g) + 3H₂(g) <=> 2NH₃(g)
Volume of reactants = 1 + 3 = 4 LVolume of products = 2 LThus, we can conclude that increasing the volume (i.e decreasing the pressure) of the reaction will favors the backward reaction, hence, more N₂ and H₂ would be produced.

The moles of gas that occupies 30.0 L is 81.64 L.
Generally, the combined gas law expresses the relationship which is established between the pressure, volume, and absolute temperature of a fixed amount of gas.
From the formula we know that,
P1V1 /T1 = P2V2/T2
P1 = 1.0 atm , V1 = 57.9 L , T1 = 300 K
P2 = 1.0 atm , V2 = ? , T2 = 423 K
As pressure is constant, so
V1/T1 = V2/T2
V2 = (V1T2/T1)

V2 = (57.9 x 423 / 300)
V2 = 81.64 L

Answers
The theoretical yield of aspirin given that 3.52 mL of acetic anhydride reacts with 0.9457 g of salicylic acid would be 1.234 g.
What is the theoretical yield of reactions?The theoretical yield of a reaction is otherwise known as the stoichiometrical yield of the reaction. It is the amount of product formed from a reaction based on the law of conservation of atoms.
Aspirin is produced when acetic anhydride reacts with salicylic acid according to the following equation:
\(C_4H_6O_3 + C_7H_6O_3--- > C_9H_8O_4 + C_2H_4O_2\)
The mole ratio of acetic anhydride and salicylic acid is 1:1.
Since: mole = mass/molar mass
0.9457 g salicylic acid is equivalent to:
0.9457/138.121 = 0.006847 mol
Thus, the equivalent mol of aspirin that would be formed would also be 0.006847 mol.
Since: mass = mol x molar mass
0.006847 mol aspirin would be:
0.006847 x 180.158 = 1.234 g
