Based on the electron configuration of the two atoms predict the ratio of metal cationic (+) atom to nonmetal anionic (-) atom in the compound hence the ratio is 1:1.

<h3>What does the octet rule say?</h3>

The Octet Rule states that the atoms of the elements bond to each other in an attempt to complete their valence shell (the last shell of the electrosphere).

Basically, they obey the octet rule which states that the capacity of atoms (e.g. here Magnesium and Sulfur) to prefer to have 8 (eight) electrons (e-) in their respective valence shells. In this case, Magnesium is Mg (+2) and Sulfur is (-2) hence the ratio is 1:1.

What state of matter is glass? Why does this seem odd?

melamori03 [73]

Answer:

solid

Explanation:

It is called an amorphous solid because it lacks the ordered molecular structure of true solids, and yet its irregular structure is too rigid for it to qualify as a liquid.

The Earth's moon is unusually large. Two popular theories of the moon's origin include the "sister world" hypothesis, which stat

Verizon [17]

Answer: D. They show that neither theory is complete and entirely correct.

Explanation:

Theory is the set of rules and principles that describe and explain a particular phenomenon (the existence of the moon in this case) and is subject to changes as new evidence emerges that gives meaning to it.

In this sense, there are many theories about the Earth's moon formation and two of the "accepted" theories are described before the question. In addition, both theories explain in a certain way the reason why the Moon is predominantly composed of elements similar to those found on Earth.

However, both theories seem to be incomplete when trying to explain our Moon's origin.

How many moles of calcium oxide are formed when 3 moles of calcium react with oxygen?

Temka [501]

Answer:

3 moles of CaO

Explanation:

The chemical balanced equation is;

2Ca + O₂ → 2CaO

The ratio of calcium(Ca) to Calcium Oxide(Cao) in this equation is 2:2.

Now, when 3 moles of calcium react with oxygen, Cao produced will be;

3 moles of O₂ × 2 moles of CaO/2 moles of Cao = 3 moles of CaO

Silver nitrate reacts with aluminum chloride to form the insoluble compound, silver chloride. The reaction proceeds according to

viva [34]

The theoretical yield of silver chloride, AgCl is 5.2109 g

The balanced equation for the reaction is given below:

Next, we shall determine the mass of aluminum chloride, AICI₃ that reacted and the mass of silver chloride, AgCl produced from the balanced equation. This is illustrated below:

Molar mass of AICI₃ = 133.34 g/mol

Mass of AICI₃ from the balanced equation = 1 × 133.34 = 133.34 g

Molar mass of AgCl = 143.32 g/mol

Mass of AgCl from the balanced equation = 3 × 143.32 = <em>429.96 g</em>

<h3>SUMMARY</h3>

From the balanced equation above,

133.34 g of AICI₃ reacted to produce 429.96 g of AgCl.

Finally, we shall determine the theoretical yield of AgCl by the reaction of 1.616 g of AICI₃ as follow:

From the balanced equation above,

133.34 g of AICI₃ reacted to produce 429.96 g of AgCl.

Therefore,

1.616 g of AICI₃ will react to produce = $\frac{1.616 * 429.96}{133.34}$ = 5.2109 g of AgCl.

Thus, the theoretical yield of silver chloride, AgCl is 5.2109 g
