The proportion of component A by mass for substance AB is given by 75%.
Further explanation
According to Proust's Comparative Law, compounds are made from elements that maintain the same Mass Comparison, ensuring that compounds have a consistent ratio of elements.
The empirical formula presents the mole ratio of elements forming a compound.
In the case of substance AB₂, 60.0% of its mass is attributed to A.
For instance, if the mass of AB₂ is 100 grams, then the mass of A would be 60 grams, and the mass of B would be 40 grams, divided according to the coefficient in compound AB₂ which is 2, leading to 20 grams.
Thus, for compound AB, the total mass is the sum of mass A and mass B, which equals 60 grams plus 20 grams, resulting in a total mass of 80 grams.
Consequently, the percentage of compound A calculates to (60: 80) = 75%.
Answer:1
Explanation:I know this is correct because I got it right.
Answer:
334 J/g
Explanation:
The relevant data provided in the question are as follows:
Mass (m) = 1 g
Specific heat of Fusion (Hf) = 334 J/g
Heat (Q) =?
By applying the formula Q = m·Hf, we can calculate the heat released:
Q = m·Hf
Q = 1 x 334
Q = 334 J
Thus, the total heat released amounts to 334 J.
Answer:
B
Explanation:
This combination forms a buffer solution, meaning it will effectively neutralize and not significantly alter the pH level.
