Answer:

disulfur tetroxide

Explanation:

Since both sulfur (S) and oxygen (O) are nonmetals, the compound is covalent. In covalent compounds, the IUPAC name includes the names of both the elements. However, the element listed last (oxygen) needs the suffix -ide. Furthermore, there should be a prefix denoting the amount of each element. The subscripts give you these amounts.

As such, if there are 2 (di-) sulfur atoms and 4 (tetra-) oxygen atoms in the compound, the IUPAC name must be disulfur tetroxide.

What happens to the partial pressure of oxygen in a sample of air if the temperature is increased? It increases. It decreases. I

Leno4ka [110]

The partial pressure of oxygen in a sample of air increases if the temperature is increased.

Answer: Option 1

Explanation:

According to Guy-Lussac's law, at constant volume, pressure exhibited by the gas molecules will be directly proportional to the temperature of the gas molecules. It is also known that pressure of mixture of gas molecules is the sum of partial pressure of each gas molecule in the mixture.

If the temperature increases, the partial pressure and the pressure of the mixture of gas also tend to increase. As it can be seen that at higher altitudes, the low temperature leads to the decrease in oxygen's partial pressure in the air.

So, it can also be concluded that temperature increases the oxygen's partial pressure in air increases.

Predict the products of La(s) + O2(aq) ->

mina [271]

Answer:

i. La (s) + O2 (g) => LaO2 (s)

ii. La (s) + O2 (g) => La2O (s)

III. La (s) + O2 (g) => La2O3 (s)

Explanation:

Hello there!

When you are given such a problem for completing the chemical equations, what you have to understand is that metals are found in groups I, II and III. While Oxygen is a group VI element.

From the above question I have considered that my La(s), solid is either Sodium (Na) - group I, Magnesium - group II and Aluminum - group III.

In a reaction, there is exchange of electrons given by their oxidation numbers (I, II and III - for our metals above)

The chemical equations are thus;

i. Na (s) + O2 (g) => NaO (s)

ii. Mg (s) + O2 (g) => Mg2O (s)

iii. Al (s) + O2 (g) => Al2O3 (s)

Relate this to the problem and it will be;

i. La (s) + O2 (g) => LaO2 (s)

ii. La (s) + O2 (g) => La2O (s)

III. La (s) + O2 (g) => La2O3 (s)

I hope this helps you to understand better. Enjoy your studies

Which compound is an Arrhenius base?

Dmitry_Shevchenko [17]

I was hoping that some choices would be given to choose from. As there are no choices given, so i am answering the question based on my knowledge and hope that it comes to your help. Calcium hydroxide is a good example of Arrhenius base. An Arrhenius base is actually a substance that releases a hydroxyl ion in water.

What is the ground state shorthand notation for iron (Fe)?

mario62 [17]

Answer:For Fe

Z=26

Explanation:

1s2 2s2 2p6 3s2 3p6 4s2 3d6

Are there 26 electrons here? Why should there be 26?

So going back to the inert gas, argon ( Z=18 ), we get

[Ar] 4s2 3d6

Make sure to check your work by counting the electrons you have
