Answer:
7
Explanation:
N-14 has 7
i looked it up ye ur probably gonna get it right
Answer:
Explanation:
In this case, for the dissociation of hypochlorous acid, we know that the acid dissociation constant (Ka) is 2.9x10⁻⁸, which is related with the Gibbs free energy as shown below:
But in this case K is just Ka, therefore, at 296 K, it turns out:
Such result, means that the reaction is nonspontaneous at the given temperature, it means it is not favorable (not easily occurring).
Best regards.
Of these four liquids, which is the most viscous?
Answer: Out of all the options presented above the one that is the most viscous liquid is answer choice D) Hg. Mercury has a Dyn. viscosity of 1.55 mPa·s. This liquid is often used for thermometers, barometers, manometers and many other devices.
I hope it helps, Regards.
Answer:
Error in measure= 1.55-1.32= 0.23
Orville's % error = 0.23/1.32*100% = 17.42%
Explanation:
Answer:
C) It explains why mass is conserved
Explanation:
The experimental studies carried out by Antoine Laurent Lavoisier led him to conclude that in a chemical reaction, which takes place in a closed system, the sum of the masses of the reagents is equal to the sum of the masses of the products, as in the following scheme:
m (reagents) = m (products)
* Where m represents mass
Thus, for example, when 4 grams of hydrogen (H) react with 16 grams of oxygen (O), 20 grams of water (H₂O) are formed.
So also if 14 grams of carbon (C) react with 34 grams of oxygen, 48 grams of carbon dioxide (CO₂) are formed.
In short, the law of conservation explains that the proportion, by mass, of the elements that participate in the composition of a substance is always constant and does not depend on the chemical process by which the substance is obtained.
