Question 8 Lithium is a solid phase of lithium still unknown to science. The only difference between it and ordinary lithium is

trapecia [35]

Answer:

the density of lithium will be equal to: 0.582 g/cm^3

Explanation:

We have the following data:

a = 430 pm = 4.3x10^-8 cm

molar mass of lithium MM = 6.97 g/mol

Since the cubic cell of lithium is cubic centered in the face, its value of Z will be equal to 4

Avogadro´s number AN = 6.022x10^23 particles/mol

using the following formula we will calculate the density of lithium:

d = (Z*MM)/(a^3*AN) = (4*6.97)/((4.3x10^-8)^3*(6.022x10^23)) = 0.582 g/cm^3

A 360. mg sample of aspirin, C9H8O4, (molar mass 180. g), is dissolved in enough water to produce 200. mL of solution. What is t

Gemiola [76]

Answer:

Molarity = 0.01 M

Explanation:

Molarity is used to measure the concentration of a solution. It will be same for the whole solution or a small amount of solution if the solution is homogeneous.

So, <u>Molarity of 200 mL of solution = Molarity of 50 mL of solution</u>

$\mathbf{Molarity = \frac{number \ of \ moles \ of \ solute}{Volume \ of \ solution \ (in \ liters)}}$

$\mathbf{Moles = \frac{given \ mass \ of \ compound}{molar \ mass \ of \ compound}}$

given mass of aspirin = 360 mg = 0.36 g

molar mass of aspirin = 180 g

Volume of solution = 200 mL = 0.2 L

$\mathrm{Mole \ of \ Aspirin = \frac{0.36}{180} = \mathbf{0.002 \ moles}}$

$\mathrm{Molarity = \frac{0.002}{0.2} = \mathbf{0.01 \ M}}$

Therefore, Molarity = 0.01 M

When metals bond with metals, the bond will be

Harman [31]

Answer:

While ionic bonds join metals to nonmetals, and covalent bonds join nonmetals to nonmetals, metallic bonds are responsible for the bonding between metal atoms. In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize.

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
