Given the equation C3H8(g) + O2(g) = CO2(g) + H2O(g) and that the enthalpies of formation for H2O(g) = -241.8 kJ/mol, CO2(g) = -

kari74 [83]

Answer: 72.4 kJ/mol

Explanation:

The balanced chemical reaction is,

$C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(l)$ $\Delta H=-2220.1kJ/mol$

The expression for enthalpy change is,

$\Delta H=\sum [n\times \Delta H_f(product)]-\sum [n\times \Delta H_f(reactant)]$

$\Delta H=[(n_{CO_2}\times \Delta H_{CO_2})+(n_{H_2O}\times \Delta H_{H_2O})]-[(n_{O_2}\times \Delta H_{O_2})+(n_{C_3H_8}\times \Delta H_{C_3H_8})]$

where,

n = number of moles

$\Delta H_{O_2}=0$ (as heat of formation of substances in their standard state is zero

Now put all the given values in this expression, we get

$-2220.1=[(3\times -393.5)+(4\times -241.8)]-[(5\times 0)+(1\times \Delta H_{C_3H_8})]$

$\Delta H_{C_3H_8}=72.4kJ/mol$

Therefore, the heat of formation of propane is 72.4 kJ/mol

1. How many moles of Cu are in 1.48 × 1025 Cu atoms?

morpeh [17]

1 mole ------------- 6.02 x 10²³ atoms
( moles Cu) ------- 1.48 x 10²⁵ atoms

moles Cu = ( 1.48 x 10²⁵ ) x 1 / 6.02 x 10²³

moles Cu = 1.48 x 10²⁵ / 6.02 x 10²³

= 24.58 moles of Cu

hope this helps!

1. An endoskeleton is the internal support of the structure of an organism like bone, cartilage etc. An exoskeleton is a complex rigid outer covering of an organism which protects the muscles and soft tissues inside like a crab shell. Remember it like 'en' in endoskeleton is to enter so its inside, and 'ex' in exoskeleton is to exit so outside the animal.

2. Bone marrow is a semi-solid tissue which is inside the spongy part of bones. There are different colored bone marrow, and the different ones are just located in different types of bones. Bone marrow is important and helps because it is the primary location where the production of new blood cells occur.

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 "You must find happiness where you are".

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
