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

What is the likeliest limiting factor restricting phytoplankton to approximately the top ten feet of the ocean, rather than deep

dedylja [7]

quantity of light

Explanation:

The likeliest limiting factor that restricts phytoplankton to approximately the top ten feet of the ocean rather than deeper is the quantity of light available.

Phytoplankton are plants and they are the major producers in bodies of water.
The require the process of photosynthesis to manufacture their food.
During photosynthesis, phytoplankton takes in carbon dioxide and water and uses light to produce food in the process.
This life activity greatly relies on light.
The upper part of the ocean usually from 0-200m depth is the photic zone.
Deeper water is aphotic and receives little to no sunlight.
The photic zone is the zone where light reaches in water.
There is abundance of light in the photic zone.

Basile [38]

During the experiment, scientists noted that several of the reaction beakers became hot to the touch. All of the following reactions could cause this result except endothermic and positive ∆H experiments.

<u>Explanation:</u>

If the beakers are becoming hot during experimentation, then that means the energy is being released from the reactants during this experiment. As the energy is being released that enthalpy change will also be negative as the enthalpy change is calculated as the difference of enthalpy of reactants from products.

So in these cases, heat is released making the beakers hot. So for the exceptional case, the experiment should be endothermic in nature and positive enthalpy change should be there in the experiment. Such that the heat will not be released leading to no heating of beakers.

5. How does the abundance of isotopes of an element relate to its average atomic mass?

alukav5142 [94]

<span>The average atomic mass of an element is the mass you see on a periodic table for that element. It is a weighted average of all the isotopes for that element based on the percentage of how much of an element is a specific isotope and the mass of each isotope. If an element has an abundance of isotopes, the isotopes with the highest and lowest masses may be more significantly different than the average atomic mass for elements with fewer isotopes.</span>
