The unbalanced chemical reaction is
<span>Na (s) + H2O (g) yields NaOH (aq) + H2 (g)

By inspection,
There is 1 mole of Na in both sides
There is 2 moles of H in the left and 3 moles in the right side.
</span>There is 1 mole of O in both sides
<span>
We balance the reaction by:


</span>2Na (s) + 2H2O (g) yields 2NaOH (aq) + H2 (g)

The answer is 2

How many atoms of iodine are in 12.75g of CaI2? Hint. How many Iodines are there in one CaI2 particle?
xenn [34]

Answer:

5.225x10^{22}atoms\ I

Explanation:

Hello!

In this case, since 12.75 g of calcium iodide has the following number of moles (molar mass = 293.89 g/mol):

n_{CaI_2}=12.75gCaI_2*\frac{1molCaI_2}{293.89gCaI_2}=0.0434molCaI_2

In such a way, since 1 mole of calcium iodide contains 2 moles of atoms of iodine, and one mole of atoms of iodine contains 6.022x10²³ atoms (Avogadro's number), we compute the resulting atoms as shown below:

atoms\ I=0.0434molCaI_2*\frac{2molI}{1molCaI_2} *\frac{6.022x10^{23}atoms\ I}{1molI} \\\\atoms\ I = 5.225x10^{22}atoms\ I

Best regards!

if 60.2 grams of Hg combines completely with 24.0 grams of Br to form a compound what is the percent compostiton of Hg in the co
Kazeer [188]

Answer:

71.5 %

Explanation:

                mercury + bromine ⟶ compound

Mass/g:       60.2          24.0

According to the <em>Law of Conservation of Mass</em>, the mass of the product must equal the mass of the reactants

Mass of product = 60.2 + 24.0

Mass of product = 84.2 g

The formula for <em>percent composition</em> is

% by mass = mass of component/total mass × 100 %

% Hg = 60.2/84.2 × 100

% Hg = 0.7150 × 100

% Hg = 71.5 %

You must find happiness right where you are lyrics
Vlad [161]

Answer:

I'm guessing this is for "Where you are" from Moana as it's the only song I could find that goes <em>"You must find happiness where you are".</em>

Lyrics:

Moana, make way, make way

Moana, it's time you knew

The village of Motunui is

All you need

The dancers are practicing

They dance to an ancient song

(Who needs a new song? This old one's all we need)

This tradition is our mission

And Moana, there's so much to do (make way)

Don't trip on the taro root

That's all you need

We share everything we make (we make)

We joke and we weave our baskets

The fishermen come back from the sea

I wanna see

Don't walk away

Moana, stay on the ground now

Our people will need a chief

And there you are

There comes a day

When you're gonna look around

And realize happiness is

Where you are

Consider the coconut (the what?)

Consider its tree

We use each part of the coconut

That's all we need

We make our nets from the fibers

The water is sweet inside

We use the leaves to build fires

We cook up the meat inside

Consider the coconuts

The trunks and the leaves

The island gives us what we need

And no one leaves

That's right, we stay

We're safe and we're well provided

And when we look to the future

There you are

You'll be okay

In time you'll learn just as I did

You must find happiness right

Where you are

I like to dance with the water

The undertow and the waves

The water is mischievous

I like how it misbehaves

The village may think I'm crazy

Or say that I drift too far

But once you know what you like, well

There you are

You are your father's daughter

Stubbornness and pride

Mind what he says but remember

You may hear a voice inside

And if the voice starts to whisper

To follow the farthest star

Moana, that voice inside is

Who you are

We make our nets from the fibers

The water is sweet inside

We use the leaves to build fires

And cook up the meat inside

The village believes in us

The village believes

The island gives us what we need

And no one leaves

So here I'll stay

My home, my people beside me

And when I think of tomorrow

There we are

I'll lead the way

I'll have my people to guide me

We'll build our future together

Where we are

'Cause every path leads you back to

Where you are

You can find happiness right

Where you are

Where you are
