Answer:
The volume of sodium hydroxide at the equivalence point is:
- <u>14.9 mL of sodium hydroxide</u>.
Explanation:
<u>The equivalence point occurs when, in this case, the HCl is completely neutralized with the solution of NaOH, how you can see this doesn't occur in the last point but occurs in the nineteenth point, where the pH is no more acid (below to 7) but is 11 approximately</u>, then you must see in the X-axis from this point and you can see the volume is almost 15, by this reason I calculate the valor of 14.9 milliliters.
Answer:
Magnesium loses two electrons.
Explanation:
- As clear from the reaction Mg converted from <em>Mg(s) to Mg²⁺</em>, so Mg converted from the oxidation state (0) to (2+).
<em>∴ Mg losses two electrons.</em>
- Cl⁻ remains as it is, so it is considered as a catalyst and neither loss nor gain any electrons.
<em>So, the correct choice is Magnesium loses two electrons.</em>

Answer:
The answer to your question is P2 = 342 kPa
Explanation:
Data
Pressure 1 = P1 = 155 kPa
Volume 1 = V1 = 22 l
Pressure 2 = P2 = ?
Volume 2 = V2 = 10 l
Temperature = constant
Process
1.- Write the equation of the combined gas law
P1V1/T1 = P2V2/ T2
Cancel T1 and T2 because they measure the same
P1V1 = P2V2
-Solve for P2
P2 = P1V1/V2
2.- Substitution
P2 = (155 x 22) / 10
3.- Simplification
P2 = 3410 / 10
4.- Result
P2 = 342 kPa
Answer:
The first claim is false. Natural resources can most definitely exist without synthetic products.
Explanation:
All synthetic products are derived from natural resources as everything has to come from a source in the beginning. However, most natural resources themselves are the source, make sense? For example, water is a naturally occurring resource, but even water is derived from specific components, however it doesn't need anything synthetic to exist. Now take hairspray, to make hairspray you need water and synthetic resources, see where I'm going with that?
