Answer:
What can you learn from blood spatter? You can learn the origin of stain, direction of impact, speed, position of victim and assailant, number of blows, shots.
To get the ∆S of the reaction, we simply have to add the ∆S of the reactants and the ∆S of the products. Then, we get the difference between the ∆S of the products and the ∆S of the products. If the <span>∆S is negative, then the reaction spontaneous. If the otherwise, the reaction is not spontaneous.</span>
Answer: The particles in a solid are packed very close to each other.
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
