Answer:
a.) 294.12 g/mol
Explanation:
1 equivalent of fatty acid reacts with 1 equivalent of NaOH.
As in the titration are required 0.0034 equivalents of NaOH, the equivalents of fatty acids = moles of fatty acids are:
0.0034 moles of fatty acids
Molar mass is defined as the ratio between mass of substance in a determined amount of moles. The mass of the fats was 1 gram, that means the molar mass is:
1g / 0.0034moles =
294.12g/mol
Right option is:
<h3>a.) 294.12 g/mol
</h3>
Answer:
If another scientist give better reasons;if they tested their hypothesis and it was wrong; if someone proved whatever the idea was to be wrong
Explanation:
I mean the list can go on at this point
Answer:
See explanation
Explanation:
An unbalanced chemical equation does not show equal number of atoms of each element on both sides of the reaction equation.
a) KOH + H3PO4 -----> K3PO4 + 3H20
b) Zn + AgCl -------> ZnCl2 + Ag
c) NaHCO3 → Na2CO3 + H2O + CO2
d) NH4NO2 ------> N2 + H2O
e) CO2 + KOH -----> K2CO3 + H2O
Kinetic energy is converted to potential energy because while it is not actually doing work, it has the potential to do work. If we drop the object from the shelf or release the spring, that potential energy is converted back into kinetic energy.
Hello! Your answer would be a gain of electrons and a decrease in positive charge.
Contrary to how it sounds, reduction is actually a gain of electrons. It is part of a set of reactions known as a redox reaction, reduction being a gain of electrons and oxidation being a loss.
With the gain of electrons, the element would become more negative as electrons bring with them a negative charge. Therefore, this would decrease the positive charge.
Hope this helped!
