Make a claim for why caco3 reacts more vigorously with hcl than with hc2h3o2

1 answer:

3 0

CaCO₃ reacts more vigorously with HCl than with CH₃COOH because HCl is a strong acid and acetic acid is a weak acid.

<h3>What is calcium carbonate?</h3>

Calcium carbonate (CaCO₃) is a salt of strong base and weak acid so that it can react with any acid.

Among hydrochloric acid (HCl) and acetic acid (CH₃COOH), HCl is a strong acid means it completely dissociates into their respective ions and acetic acid is a weak acid. So due to strong basic nature of calcium carbonate it vigorously reacts with strong HCl acid.

Hence due to strong acidity of HCl, CaCO₃ vigorously react with HCl.

All weather is energy in motion. Where does the energy come from

alekssr [168]

Answer:

The Sun radiates huge amounts of energy. Only a small portion of that energy hits the Earth, but it is enough to light our days, heat our air and land, and create weather systems over the oceans. Most of the energy you will learn about comes from the Sun. The Earth also gives off energy.

The purpose of the salt bridge in an electrochemical cell is to ____.

IgorLugansk [536]

Answer:

A. maintain electrical neutrality in the half-cells via migration of ions

Explanation:

Salt bridge -

For an electrochemical reaction , involving an anode and a cathode , both the electrodes are connect via a salt bridge to complete the circuit for the reaction .

One of the very important use of a salt bridge is to maintain the electrical neutrality of the respective half cells , which is achieved by the movement of ions .

Hence , from the given options , the correct option is ( a ) .

39. Analyze What subscripts would you most likely use if

Igoryamba

Based on their valencies, the subscripts of the ionic compounds formed will be:

1 and 1
2 and 1
1 and 2
2 and 2

<h3>What subscripts would you most likely use if the following substances formed an ionic compound?</h3>

A. An alkali metal and a halogen.

An alkali metal and a halogen both have valencies of one.

Therefore the subscripts would be 1.

B. An alkali metal and a non-metal from group 16.

An alkali metal has a valency of 1 and a group 16 non-metal has a valency of 2.

By exchange of valencies, the subscript would be 2 and 1.

C. An alkaline earth metal and a halogen.

An alkaline earth metal has a valency of 2 and a halogen has a valency of 1.

By exchange of valencies, the subscripts would be 1 and 2.

D. An alkaline earth metal and a non-metal from group 16.

An alkaline earth metal has a valency of 2 and a non-metal from group 16 has a valency of 2.

By exchange of valencies, the subscripts would be 2 and 2.

Therefore, the subscripts of the ionic compounds formed will be:

1 and 1
2 and 1
1 and 2
2 and 2
