Answer:
Explanation:
Hello!
In this case, when acetic acid is titrated with sodium hydroxide, the following chemical reaction is carried out:
Whereas there is a 1:1 mole ratio between the acid and the base, which means that at the equivalence point we evidence:
Which in terms of volumes and concentrations is written as:
Thus, solving for the required volume of base, we obtain:
Best regards!
Potential energy U= k*Q*q/r
doubling the charge Q doubles the potential energy. Since this will just be converted into kinetic energy u will double tht
The tendency of a moving object to continue moving in a straight line or a stationary object to remain in place is called inertia.
Answer: C) or the third option.
Data:
Molar Mass of NaOH = 40 g/mol
Solving: <span>According to the Law Avogradro, we have in 1 mole of a substance, 6.02x10²³ atoms/mol or molecules
</span>
1 mol -------------------- 6.02*10²³ molecules
y mol -------------------- 2.70*10²² molecules
6.02*10²³y = 0.270*10²³
Solving: <span>Find the mass value now
</span>
40 g ----------------- 1 mol of NaOH
x g ------------- 0.04 mol of NaOH
Answer:
The mass is 1.6 grams
