Answer:
Below
Explanation:
Salt solution, aka saline solution, is a homogeneous mixture. This means that the mixtures composition is completely uniform throughout. If you were to look at a saline solution, it would just look like plain water because the salt is dissolved (it looks the exact same in the entire mixture).
Something like bean soup would be an example of a heterogeneous mixture. You can see all the beans and vegetables as components of one mixture.

The answer is (2) 10.0 mol. The equation given is balanced. So the ratio of mol number of compound is the ratio of the number before the compound. The HCl and CO2 ratio is 2:1. So the answer is 10.0 mol.
Option 2, Br. I'll go over why all other three options are incorrect.
Option 1 - Krypton is a Noble gas, and so it doesn't need to accept electrons since it has an octet.
Option 3 and 4 - Both Calcium and Barium are alkaline earth metals, and give away electrons, since they only have 2.

Answer:
See detailed reaction equations below
Explanation:
a) Mg(s) +2HBr(aq) ----------------> MgBr2(aq) + H2(g)
b) Ca(ClO3)2(s) ------------> CaCl2(s) + 3O2(g)
c) 3BaBr2(s) +2Na3PO4(aq) ------------> Ba3(PO4)2(s) + 6NaBr(aq)
d) 3AgNO3(aq) + AlI3(aq) --------------> 3AgI(s) + Al(NO3)3(aq)
Balancing reaction equations involves taking valencies and number of atoms of each element on the reactants and products side into consideration respectively.
pH=-lg[H⁺]
[H⁺] is the molar concentration of hydrogen protons
both solutions have the same concentration of the monoprotic acid so they will both have the same pH
pH=-lg0.1=1 because 10 at the power of -1 is equal to 0.1 but the sign is changed
