Hello!
The general chemical equation for the neutralization of an acid HA with NaOH is the following:
HA(aq) + NaOH(aq) → NaA(aq) + H₂O(l)
For determining the concentration of the acid solution, we can use the equation shown below:
So, the concentration of the Acid is
0,36 MHave a nice day!
Answer:
H2O is the chemical formula for water or in simple language its is water
Explanation:
Answer:
47, 68, 47
Explanation:
Let's consider the following isotope: ¹¹⁵Ag.
If we look in the Periodic Table, the atomic number of Ag is 47, that is, silver has 47 protons.
Since ¹¹⁵Ag is neutral it must have the same number of protons that of electrons. Then, it also has 47 electrons.
The number 115 in ¹¹⁵Ag stands for the mass number, which is the sum of protons and neutrons. Then, the number of neutrons is:
p⁺ + n⁰ = 115
n⁰ = 115 - p⁺ = 115 - 47 = 68
The number of protons, neutrons, and electrons in ¹¹⁵Ag is: 47, 68, 47.
Al4C3 + 12H2O = 4Al(OH)3↓ + 3CH4

Colloids have small non-dissolved particles that flow around in the mixture. These particles do not settle over time. When a light is shined on colloids the scattering characteristic of the Tyndall effect are visable.</span>
