Hydrogen is a reactive gas under normal conditions.Based on this property alone, to which group of the periodic table should hyd

denis23 [38]

Even though Hydrogen is originally in group 1, based on this property, we can say it is in group 6.

Because:

Group 6 would mean that it only needs 2 more valence electrons till the octet (8 valence electrons). This would make it reactive, yet, in normal conditions, unlike group 7.

Which is the correct name for p2o5? phosphorus dioxide phosphorus pentoxide diphosphorus pentoxide diphosphorus hexaoxide

Elenna [48]

Correct option:

The correct name for $P_{2}O_{5}$ is diphosphorus pentoxide.

Why $P_{2}O_{5}$ is called diphosphorus pentoxide?

$P_{2}O_{5}$ is commonly known as diphosphorus pentoxide.

Phosphorus pentoxide has an intriguing property in that $P_{2}O_{5}$ is actually its empirical formula, whereas $P_{4}O_{10}$ is its actual molecular formula.

However, the name of the chemical was obtained from its empirical formula rather than from its molecular formula. The official name for this substance is diphosphorus pentoxide.

Oxygen-containing binary compounds have "oxide" as their "last name." Phosphorus is the "first name."

We list each atom's numbers below:

The di- and Penta- prefixes are used to indicate the presence of two and five oxygen atoms, respectively, in the molecule.

Someone help it’s due today

Kitty [74]

Answer:

All elements are neutral

Explanation:

The plum pudding model of the atom indicated that all elements are neutral. The model was proposed by J.J Thomson after he conducted his experiment on the gas discharge tube.

From the experiment he discovered electrons which he called cathode rays.

Therefore, he suggested the plum pudding model of the atom.

The model describes negatively charge sphere surrounded by positive charges to balance them.

A 32.8 g sample of gas occupies 22.414 L at STP. What is the molecular weight of this gas?

olasank [31]

Answer:

32.8g/mole

Explanation:

Given parameters:

Mass of sample of gas = 32.8g

Volume = 22.4L

Unknown:

Molecular weight = ?

Solution:

To solve this problem we must understand that at rtp;

1 mole of gas occupies a volume of 22.4L

Number of mole of the gas = 1 mole

Now;

Mass = number of moles x molecular weight

molecular weight = $\frac{mass}{molecular weight}$ = $\frac{32.8g}{1mole }$ = 32.8g/mole
