Answer: 0.0738 M
Explanation:
1) Chemical equation:
<span>HNO₃ + LiOH → LiNO₃ + H₂O
</span>
2) Mole ratios:
1 mol HNO₃ neutralizes 1 mol LiOH
3) Number of moles of H⁺ from HNO₃:
M = n / V ⇒ n = M × V = 0.050 liter × M
4) Number of moles of OH⁻ from LiOH
M = n / V ⇒ n = M × V = 0.03690 liter × 0,100 M
5) Equivalence point:
number of moles of H⁺ = number of moles of OH⁻
⇒ 0.0500 × M = 0.03690 × 0.100
⇒ M = 0.03690 × 0.100 / 0.0500 = 0.0738 M

Answer:
I believe that the answer is none, chemistry is important in all of these subjects.
Answer is: in this experiment it is best to use some liquid alkanes (for example hexane), because gasoline<span> consists of hydrocarbons with between four and twenty carbon atoms</span>. Gasoline is a mixture <span> of many different hydrocarbons: </span><span>alkanes (paraffins), cycloalkanes and alkenes (olefins).</span>
Answer:
C
Explanation:
how long it takes to reach equilibrium
Answer: 
Explanation:
In thermodynamics, entropy (symbolized as S) is a physical quantity for a thermodynamic system in equilibrium. It measures the number of micro states compatible with the macro state of equilibrium,<u> it can also be said that it measures the degree of organization of the system</u>, or that it is the reason for an increase in internal energy versus an increase in the temperature of the system.
If we assume we have 0.6 mol of an ideal gas at 350 K at an initial pressure of 0.75 atm, we calculate the entropy change as:
Where S is entropy, n is the number of moles, R is the gas constant R is 8.314 J / mol·K, P1 is the initial pressure and P2 is the final pressure. Then we substitute the values and solve for S.
