2 Na + 2 H2O --> 2 NaOH + H2
Answer:
Explanation:
Boyle's law states that:
"For an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume".
Mathematically:

where
p is the pressure of the gas
V is the volume of the gas
The important condition in order to verify Boyle's law in an experiment is that the temperature of the gas must remain constant. This means that the temperature of the gas during the experiment must be kept constant. This can be achieved, for example, by placing the apparatus containing your gas (for example, a glass tube) inside a thermal bath: for instance, a large amount of water kept at constant temperature. This way, the gas inside the tube will also have the same temperature of the water, which is constant.

Answer:
• pH = 3.0
• pH = 2.70
• pH = 3.61
• pH = 8.28
• pH = 1.40
Explanation:
El pH es una medida en química usada para determinar el grado de acidez o basicidad en una solución.
Se define como:
pH = -log₁₀ [H⁺]
<em>El - logaritmo de la concentración molar de H⁺</em>
<em />
Para las concentraciones de H⁺ dadas:
• [H+] = 0.001 M
pH = -log (0.001M) = 3
pH = 3.0
• [H+] = 0.002 M
pH = -log (0.002M)
pH = 2.70
• [H+] = 2.45X10-4 M
pH = -log (2.45X10-4 M )
pH = 3.61
• [H+] = 5.2X10-9 M
pH = -log (5.2X10-9 M)
pH = 8.28
• [H+] = 0.04 M
pH = -log (0.04M)
pH = 1.40
Add barium chloride. Reaction equation as shown:
Li2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2LiCl(aq)
Reaction will result in a white precipitate, making the solution look milky.
Answer:
The diagram is attached.
Explanation:
Peptide just refers to two or more amino acids liking together. A dipeptide consists of two amino acids linking together. A polypeptide is more that two amino acids linking together.
