Answer:

A charge of -3

Explanation:

If you look on a periodic table you will find that phosphorus is 3 elements away from the nearest noble gas argon. This means that phosphorus would prefer a charge of -3!

Answer:typically it will be -3

Explanation:

It prefers to take up 3 electrons and thereby become phosphide with a -3 charge. since it is a nonmetal it will take up electrons making it negative as an ion. In order to fill up its last shell, to become stable, to form an octet it will need 3 added electrons which will give it that -3 charge. An atom of phophorus will be neutral, An ion of phsphorus will have a -3 charge.

hope this helped.:)

Explanation:

Yes, the number of moles of oxygen gas produced by your reaction under those conditions for pressure and temperature will be 0.0025.

Hydrogen peroxide,

, decomposes to give water and oxygen gas according to the balanced chemical equation

You've collected 0.061 L of oxygen gas at 295.15 K and 1 atm, so you've got all the data you need to calculate the number of moles of oxygen gas produced by using the ideal gas law equation

⇒

0.0025 moles

So, if this was your first question, then yes, your reaction produced 0.0025 moles of oxygen gas.

I find the second part of your question to be a little confusing. You were given the density of the hydrogen peroxide solution, so are you supposed to use that to determine the theoretical number of moles of oxygen for this reaction?

I'm not sure what

100%

1.02 g/mL

means, do you have a certain volume of hydrogen peroxide solution?

SIDE NOTE According to the additional information posted by Heather, it turns out that the initial hydrogen peroxide solution had a volume of 5 mL.

Even with the volume of the initial solution, you'd need its percent concentration to try and determine exactly how many moles you had present before the reaction.

Once you know how many moles of hydrogen peroxide you had, assume that all of the react and use the

mole ratio that exists between

and

to get the number of moles of oxygen your reaction could have produced.

Calcula el pH de las siguientes sustancias formadas durante una erupción volcánica:

Virty [35]

Calculate the pH of the following substances formed during a volcanic eruption:

• Acid rain if the [H +] is 1.9 x 10-5

• Sulfurous acid if [H +] = 0.10

• Nitric acid if [H +] = 0.11

<h3>Further explanation </h3>

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]
