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

Which hold more heat for longer period of time ? <br><br> A. Air <br> B. Water
Mandarinka [93]

Answer:

water

Explanation:

The heat capacity of a material, along with its total mass and its temperature, tell us how much thermal energy is stored in a material. ... <u>The result is that the temperature of the water cube is much more stable than the air — the water changes much more slowly; it holds onto its temperature longer.</u>

Which of the following is not a state of matter?
vladimir1956 [14]

Answer: Option (C) is the correct answer.

Explanation:

Solid and liquid are the states of matter. Plasma is also a state of matter where a number of electrons move freely around the nucleus of an atom.

Whereas water is a liquid itself and liquid is a state of matter but water is not a state of matter.

Therefore, we can conclude that water is not a state of matter.
