Answer:
Answer B
Explanation:
By definition mixtures are combinations of substances physically prepared and physically separated. Mixtures are classified as 'homogeneous mixtures' and 'heterogeneous mixtures'. For homogeneous mixtures all components are dissolved, with solute evenly distributed throughout the solution and assumes state of solvent. 'Heterogeneous mixtures' have inconsistent properties throughout and solute concentration is not consistent throughout the mixture.
Answer:
Option 3.
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Explanation:
To know which option is correct, we must have an ideal of what is acid–base neutralization.
Neutralization is a reaction involving an acid and a base which produces salt and water only.
With the above information, we can easily detect the equation describing acid-base neutralization reaction by considering the products of each reaction to see the one that has water as part of the products.
From the question given above, only the 3rd equation gas water as part of the products i.e
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Hence, equation 3 is an acid-base neutralization reaction
To determine the empirical formula of ascorbic acid, we divide the lowest fraction with the other values. For this case, we divide everything with 3.406. We do as follows:
C = 3.407 / 3.406 = 1
H = 4.53 / 3.406 = 1.33
O = 3.406 / 3.406 = 1
So, you have CHO
Hope this answers the question. Have a nice day.
The answer is 1) mixing of two gases by diffusion.
Once 2 gases are mixed by diffusion, they cannot be obtained from the mixture of gases. Hence, it is considered to be an irreversible process.
