Answer:
Following are the answer to this question:
Explanation:
In the given question information is missing, that is equation which can be defined as follows:
- Growing temperatures may change its connection to just the way which consumes thermal energy in accordance with Le chatelier concepts Potential connection is endothermic. Answer: shifts to the right
-
Kc are described as a related to the concentration by the intensity of both the reaction for each phrase which reaches a power equal towards its stoichiometric equation coefficient Kc = \frac{product}{reactant}
It increases [product] but reduces [reactant] Therefore, Kc increases
D. is the answer my mommy just told me and bubby says so too so yeah its a valid answer hope this helps!
Answer:
-3135.47 kJ/mol
Explanation:
Step 1: Write the balanced equation
C₆H₆(l) + 7.5 O₂(g) ⇒ 6 CO₂(g) + 3 H₂O(g)
Step 2: Calculate the standard enthalpy change of the reaction (ΔH°r)
We will use the following expression.
ΔH°r = ∑np × ΔH°f(p) - ∑nr × ΔH°f(r)
where,
n: moles
ΔH°f: standard enthalpies of formation
p: products
r: reactants
ΔH°r = 6 mol × ΔH°f(CO₂(g)) + 3 mol × ΔH°f(H₂O(g)) - 1 mol × ΔH°f(C₆H₆(l)) - 7.5 mol × ΔH°f(O₂(g))
ΔH°r = 6 mol × (-393.51 kJ/mol) + 3 mol × (-241.82 kJ/mol) - 1 mol × (48.95 kJ/mol) - 7.5 mol × 0 kJ/mol
ΔH°r = -3135.47 kJ
Since this enthalpy change is for 1 mole of C₆H₆(l), we can express it as -3135.47 kJ/mol.
The number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.
<h3>What are limiting reactants?</h3>
Limiting reactants are those reactants which determine the amount of product that can be formed since they get used up in a reaction.
In the making of sandwiches from bread and cheese, the limiting reactant is the material that is used up.
The formula for making a sandwich is given below;
2 pieces of bread + 1 slice of cheese = 1 sandwich
6 pieces of bread can make 3 sandwiches
4 slices of cheese can make 4 sandwiches
Thus, bread is the limiting reactant.
Therefore, the number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.
