Heres my attempt at this and hope it helps friend
.1372L * (.83M/L) = .114 mols propanoic acid
.06862L * (1.1M/L) = 0.0755 mols NaOH
using the henderson hasselbach equation
ph = pKa + log([A-]/[HA])
so
ph = 4.89 + log(.0755/.114) = 4.72
Explanation:
Identify at least three reasons the Articles of Confederations failed as a governing document. In your opinion, evaluate which defect was most debilitating, using evidence and your knowledge of American government to justify your position.
I think the answer is a but I am not for sure
Gallium metal is heated in oxygen gas, it melts and forms solid gallium(III) oxide.
Ga + O₂⇒ Ga O₂
Balance the atoms with simple - whole coefficients.
4 Ga + 3 O₂ 2 Ga₂O₃.
Specify the states of matter.
4 Ga(s) + 3 O₂ (g) ⇒ 2 Ga₂O₃.(s)
Therefore, balanced equation is----- 4 Ga(s) + 3 O₂ (g) ⇒ 2 Ga₂O₃.(s)
What is the balanced formula equation?
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
Why are equations balanced?
A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.

Answer:
<h3>The answer is 7.85 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 13.91 - 12 = 1.91 mL
We have
We have the final answer as
<h3>7.85 g/mL</h3>
