Answer:

-I dont have a calculator on me but I can explain to you how to do it and you can put it in your calculator

Explanation:

-First you have to balance the equation because its not balanced

4Na+2H2O —-> 4NaOH

-After you balance it you have to add up the grams of H2 gas,

-The mass of each element is measured in grams

- You find how many grams each element it by looking at the periodic table and looking at the number at the bottom, thats called the mass

- Afterward if the element mass you are looking for has a small number as its subscript, that means there is more than one, so you must add them together to get the correct amount of grams it has

1+1=2grams

-After that, you take that and convert it to moles

2grams x 1mole/(6.02^23)grams = (unknown) moles

-And finally you convert that answer from moles to liters

(Unknown) moles x 22.4 Liters / 1 mole = FINAL ANSWER

Answer:

Our 4 Senses

Explanation:

You see, even though we see cant see something, that doesn't mean that it isn't there, for example, bacteria, the wind, and particles. We cant see any of them, at least with just the human eye, but we still are aware that all those things are there.

Our 4 Senses can help us identify things we cant see, lets start off with our sense of "smell"

Lets say there is a amazing new chef in town who just made the best load of bread, your not sure where her/his restaurant is but you can smell that French bread all the way from your house.

You see, you know that it is there, but you cant see it! All our senses help us identify this, so just to prove my point a bit more, lets try one more sense.

Lets finish the night off with one of our other sense "Hearing"

Lets pretend there is a beautiful bird chirming, you look outside your window but you cant see the little bird, you know its there, but you cant see it.

What I'm trying to say is, even though we cant see something, it doesn't mean it isn't there, and our senses help us!

I hope this helped! If you dont understand something or would like more of an explanation, feel free to contact me! :D

Answer:

Nitrogen is the answer my good sir.

Explanation:

A. The molarity of solution containing 5.2 g of sodium sulphate is 0.0732 M

B. The number of mole of sodium in the solution is 0.0732 mole

Mole = mass / molar mass

Mole of Na₂SO₄ = 5.2 / 142

Mole of Na₂SO₄ = 0.0366 mole

Molarity = mole / Volume

Molarity = 0.0366 / 0.5

Molarity = 0.0732 M

1 mole of Na₂SO₄ contains 2 moles of Na.

Therefore,

0.0366 mole of Na₂SO₄ will contain = 0.0366 × 2 = 0.0732 mole of Na

Thus, 0.0732 mole of Na is present in the solution.

The mass, in grams, of 532.0 atoms of cadmium is 9.93 × 10⁻²⁰ g

From the question, we are to determine the mass of the given atoms of cadmium

First, we will calculate the number of moles of cadmium present

Using the formula,

[tex]Number\ of\ moles = \frac{Number\ of\ atoms}{Avogadro's\ constant}[/tex]

Then,

Number of moles of Cd present = [tex]\frac{532.0}{6.022 \times 10^{23} }[/tex]

Number of moles of Cd present = 8.83427 × 10⁻²² moles

From the given information,

1 mole of Cd has a mass of 112.41 g

Therefore,

8.83427 × 10⁻²² moles will have a mass of 8.83427 × 10⁻²² × 112.41 g

8.83427 × 10⁻²² × 112.41 = 9.9306 × 10⁻²⁰ g

≅ 9.93 × 10⁻²⁰ g

Hence, the mass, in grams, of 532.0 atoms of cadmium is 9.93 × 10⁻²⁰ g

Answer:

0.13 M

Explanation:

The reaction equation is;

NaOH(aq) + KHC8H4O4(aq) ------> KNaC8H4O4(aq) + H2O(l)

Molar mass of KHP = 204.22 g/mol

Amount of KHP= mass/ molar mass = 0.3365 g/204.22 g/mol = 1.65 × 10^-3 moles

n= CV

Where;

C= concentration

V= volume in dm^3

n= number of moles

C= n/V = 1.65 × 10^-3 moles × 1000/250 = 6.6 × 10^-3 M

If 1 mole of KHP reacts with 1 mole of NaOH

1.65 × 10^-3 moles of KHP will react with 1.65 × 10^-3 moles of NaOH

From

n= CV

We have that only 12.44 ml of NaOH reacted

C= n/V = 1.65 × 10^-3 moles × 1000/12.44

C= 0.13 M

At the equivalence point, the KHP solution turned light pink.
