Answer:
10.56 g
Explanation:
C4H10(g) + 13/2O2 (g) -------> 4CO2(g) + 5H2O(l)
Number of moles of butane = 3.49g/ 58 g/mol = 0.06 moles
1 mole butane yields 4 moles of CO2
0.06 moles of butane = 0.06 × 4/1 = 0.24 moles of CO2
Number of moles of oxygen = 17.1g/32g/mol = 0.53 moles of oxygen
6.5 moles of oxygen yields 4 moles of CO2
0.53 moles of oxygen yields 0.53 × 4/6.5 =0.33 moles of CO2
Butane is the limiting reactant
Theoretical yield of CO2 = 0.24 moles × 44g/mol = 10.56 g
Answer:
Explanation:
At 5 s the body has travelled 10 m.
Between 5 s and 10 s, the body reached 30 m.
Distance travelled = 30 m - 10 m = 20 m
Time = 10 s - 5 s = 5 s
Answer:
D) 2 NOCl(g) ⇄ 2 NO(g) + Cl₂(g); Kp = 1.7 × 10⁻²
Explanation:
In order to compare the degree of decomposition of these reactions, we have to compare the equilibrium constant Kp. Kp is equal to the partial pressure of the products raised to their stoichiometric coefficients divided by the partial pressure of the reactants raised to their stoichiometric coefficients. The higher the Kp, the more products and fewer reactants at equilibrium. Among these reactions, D is the one that has the highest Kp, therefore the one experiencing the largest degree of decomposition.
Quantum numbers are the conserved quantities in the system that expresses the position of the electron. The second quantum number describes the electron subshells.
<h3>What are quantum numbers?</h3>
Quantum numbers are the energy and the position defining values of the electron in the atomic structure. There are four basic quantum numbers, principal, magnetic, azimuthal, and spin quantum.
The second quantum number (I) is the angular quantum number that describes the magnitude of the subshells (s,p, d, and f) or the type of the subshells. It is also known as the Azimuthal quantum number.
Therefore, the second quantum number shows the electronic subshells.
