The element with the configuration 1s², 2s², 2p⁶, 3s¹ has the ionization energy of 496 kJ/mol. This is because this element has only one electron in its third shell, meaning it will release its electron quickly to attain stable configuration, causing its first ionization energy to be low.

How many moles of hydrogen atoms are in 1 mole of sulfuric acid?
Hunter-Best [27]

one mole of sulfuric acid will contain 2 moles of hydrogen atoms. The molar mass of sulfuric acid is 98.0795 g/mol. This means that every mole of sulfuric acid has a mass of 98.0795 g. Since you're dealing with one mole of sulfuric acid, it follows that you will also be dealing with two moles of hydrogen.

What is the pH of a solution of 1 x 10-5 M NaOH? Is the solution acidic or basic?
Anna007 [38]

Answer: to calculate pH use -log[H+] or - log[OH-]..the solution is basic as the “NaOH” is attached to a hydroxide.Since we need to find the pH (per hydrogen) and not the pOH( per hydroxide) we need to find the pOH of the substance first then we subtract that by 14 so we can arrive at the pH of the substance.

Explanation: So -log( 1 x 10^(-5)) = 5 which is the pOH.Now we subtract that by 14 which gives us -9 and now you’d multiply that by -1 bcuz we can’t have a negative so the pH of the substance is 9

Find the density of an object that has a mass of 28 grams and a volume of 2 points<br> 38.6 cm^3. *
Shtirlitz [24]

Answer:

<h2>0.73 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{28}{38.6}  \\  =0.72538...

We have the final answer as

<h3>0.73 g/cm³</h3>

Hope this helps you
