If 45.0 mL of a 4.00 M sodium sulfate (Na2SO4) solution is used for the reaction shown above, how many moles of sodium ions were present in solution before the reaction proceeded?​

Answers

Answer:0.360

Explanation:

I had this on ck12 yesterday

The moles of sodium ions were present in the solution before the reaction proceeded is 0.36moles

Molarity of a solution

The formula for calculating the molarity of a solution is expressed as:

Molarity = moles/volume

Given the following parameters

Molarity = 4.00M

Volume of sodium sulfate = 45mL = 0.045L

Substitute to have;

Molarity = 4 * 0,045

Molarity = 0.18

Since there are 2 atoms of sodium ion in the solution, hence the moles of sodium ions were present in the solution before the reaction proceeded is 0.36moles

is the valency of carbon 2 or 4​

Answers

Answer:

4

explanation:

Carbon has four valence electrons and here a valence of carbon is four.

Answer:

4

Explanation:

needs four electrons to complete its orbit

In your own words, explain why each of the filler blocks (s,p,d,f) on the periodic chart have their characteristic width(number) of groups.

Answers

Answer:

Each of the four blocks of the periodic table is the collection of elements that have common valence orbitals, or that their valence are found in one of the four orbitals with azimuthal quantum number 0, 1, 2, or 3 which corresponds to the shape (s), principal (p), diffuse (d), or fundamental (f) orbitals respectively

The maximum number of electrons in the s-orbital = 2 electrons

The maximum number of electrons in the p-orbital = 6 electrons

The maximum number of electrons in the d-block = 10 electrons

The maximum number of electrons in the f-orbital = 14 electrons

Therefore, given that the elements of the within each of the blocks have their valence electron in the corresponding orbital in which they are located on the periodic table, given the periodic nature of the periodic table, the width of each block of elements corresponds to the maximum number of elements that can be found in their valence orbital.

Therefore, we have;

The width of the s-block elements = 2 block units

The width of the p-block elements = 6 block units

The width of the d-block elements = 10 block units

The width of the f-block elements = 14 block units

Answers

Answer:

17.04 g/mol

Explanation:

Molar Mass of NH₃

we know that

Nitrogen has 14.01 gram/mol

And Hydrogen has 1.01 gram/mol

but we have 3 Hydrogens So we multiply

1.01 by 3 i.e., 3.03

Now, add

14.01

+ 3.03

17.04

So, The molar mass of ammonia, NH₃ is

17.04 g/mol

How many mL of ethanol would you
add to water to make 1750 mL of a
40.0% ethanol solution (v/v%)?

Answers

Answer:

700 mL of ethanol would be added

Explanation:

Given data:

Volume of ethanol added to make 40% v/v solution = ?

Total volume of solution = 1750 mL

Solution:

We will calculate the 40% 1750 mL which will be the volume of ethanol added to the water to make 40%v/v solution.

(40/100)× 1750 mL

0.4 × 1750 mL

700 mL

700 mL of ethanol would be added.
