Answer:

Na and Li. (but see below).

Explanation:

Sodium and Lithium are in Group 1 of the Periodic Table .

They have 1 electron in their valence shell which is easily lost to produce Na1+ and Li1+  ions.

The Na atom is more reactive than the Li so if you are looking for 1 answer it is Na.

Imagine that A and B are cations and X, Y, and Z are anions, and that the following reactions occur:
Darina [25.2K]

Answer: AZ is the insoluble choice.

Explanation:

Z is an anion of a weak electronegative element. Hence, it bounds lightly with the highly electropositive cation A to form AZ.

AZ is not as ionic as AX, AY, BX, BY and BZ, so it is insoluble in water and yields precipitate on reaction with the salt of a weaker metal.

How many moles of HCl are present in 0.70 L of a 0.33 M HCl solution? (molar mass of HCl = 36.46 g/mol)
Vilka [71]

Answer:-

0.231 moles

Explanation:-

From the question we are told that

Volume of HCl solution = 0.70 L

Strength of HCl solution = 0.33 M

Here M stands for molarity. Molarity is the number of moles of the substance present per Litre of solution. So in place of M we can write moles / L

Number of moles of HCl solution = Volume of HCl solution x Strength of HCl solution

= 0.70 L x 0.33 moles / L

= 0.231 moles.

0.231 moles of HCl are present in 0.70 L of a 0.33 M HCl solution
