Most reactive are on the far left.

Answer: Option (d) is the correct answer.

Explanation:

Metals are the substances that have more number of electrons. In order to attain stability, metals lose electrons and thus becomes positively charged.

A metal with less number of valence electrons will be more reactive because it will readily lose its valence electrons to become stable.

For example, atomic number of potassium is 19 with electronic distribution is 2, 8, 8, 1. Potassium is a group I element. So, to become stable it will lose its 1 extra electron readily.

Therefore, we can conclude that the most reactive metals on the periodic table are placed on to the far left.

Pls help me. Show proof on why it’s that answer.

The answer is “the sustainability of the ecosystem” because if the ecosystem isn’t sustainable enough for many different organisms to live in it then the biological diversity of the ecosystem will decrease.

Which unit conversion allows you to convert 21.0 gallons into milliliters?

Ulleksa [173]

Answer:

Explanation:

we are given

there are in 0.073 gallons

we can see that there are two non-zero places after decimals

so, there are two siginificant figures

step-1: Change gallons to quarts

we know that

1 gallon = 4 quarts

so, we can write as

step-2: Change into liter

we know that

1 liter = 1.057 quarts

step-3: Change into millilitre

we know that

Since, it is asking for only two significant figures

so, we can also write as

Why do different molecules require different masses to make 1 mol

Wewaii [24]

Answer:

Different substances have different molecular masses. Thus, equal masses have different numbers of atoms, molecules, or moles. On the other hand, equal numbers of moles of different substances have different masses.

What type of bond is this combination likely to form

kari74 [83]

Answer:

A combination is certainly possible, but you should not take formal charges so literally

Normally, when a covalent bond is found, the two atoms both bring in one electron. As you identify correctly, in the case of nitric acid that would not be possible completely. If you draw the different possible resonance structures, the most likely structure has a single bond between the nitrogen and an oxygen where the oxygen has 3 lone pairs and both electrons in the bond are donated by the nitrogen. This makes the nitrogen "positive" and that oxygen "negative", but in fact the electrons move more freely in the molecule and charges are more distributed. You will not be able to find "the negatively charged" oxygen atom.
