Answer:

Because Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. And this way, they act like the glass walls of a greenhouse. This greenhouse effect also keeps the Earth warm enough to sustain life.

How many moles of sf6 are there in 459500000000000000 molecules of sf6

Vlada [557]

Answer : The number of moles of $SF_6$ is, $7.63\times 10^{-7}$ moles.

Solution :

As we know that,

1 mole contains $6.022\times 10^{23}$ number of molecules

As, $6.022\times 10^{23}$ number of molecules of $SF_6$ are present in 1 mole of $SF_6$

So, $4595\times 10^{14}$ number of molecules of $SF_6$ are present in $\frac{4595\times 10^{14}}{6.022\times 10^{23}}=7.63\times 10^{-7}$ moles of $SF_6$

Therefore, the number of moles of $SF_6$ is, $7.63\times 10^{-7}$ moles.

What is unique about the way that transition metals form compounds?

Alika [10]

Answer:

<u><em>A. They don't form compounds</em></u>

Explanation:

High density: The strong bonding between the atoms in transition metals cause them to be tightly held together, creating a high density. Colored compounds: Transition metals tend to form more colored compounds than other elements, either in solid form or dissolved in a solvent.

How does the property of density help to identify substances?

Mashutka [201]

Answer:

Density can be useful in identifying substances. It is also a convenient property because it provides a link (or conversion factor) between the mass and the volume of a substance. Mass and volume are extensive (or extrinsic) properties of matter - they depend on amount.
