the nebular theory states that the solar systems developing rotations revolve around sun. it is located in the milky-way. revolving around the sun, with gravity pulling it, an interstellar cloud of dust and gas, is formed. (i.e. the nebula that we are speaking)

this formation is a protostar. the idea in the theory states that the nebula has flattened into a disk called the "protoplanetary disk"; and over time, the debreis eventually formed this disk. (i.e. creating the milky-way)

hopefully this helped, thank you!! :D

What specifically determines how much energy is available in a molecular

HACTEHA [7]

C The number and types of bonds within the molecule.

Explanation:

In a molecule, the number and types of bonds present determines the amount of available energy therein.

When bonds are broken or formed, energy is usually released.

Elements combine with one another in order to attain stability in this state.
Through this process, they form bonds by attraction.
Where atoms exchange their valence electrons by losing or gaining it, electrovalent bonds form.
In covalent molecules, electrons are usually shared between atoms.
An attraction result from this type of interaction.
The bond formed stores energy in the process.
When bonds are broken, energy is usually released. The energy accrues when the bond was being formed.
In molecules, we have covalent bond.

Name the functional group in the following molecule:

Anna71 [15]

Answer:

B. Aromatic

Explanation:

Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.

For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.

some inkjet printers produce picoliter-sized drops. how many water molecules are there in one picoliter of water? the density of

GrogVix [38]

3.37 x 10¹⁰ molecules

Explanation:

Given parameters:

Volume of water = 1pL = 1 x 10⁻¹²L

Density of water = 1.00g/mL = 1000g/L

Unknown:

Number of water molecules = ?

Solution:

To solve this problem, we first find the mass of the water molecule in the inkjet.

Mass of water = density of water x volume of water

Then, the number of molecules can be determined using the expression below:

number of moles = $\frac{mass of water}{molar mass of water}$

Number of molecules = number of moles x 6.02 x 10²³

Solving:

Mass of water = 1 x 10⁻¹² x 1000 = 1 x 10⁻⁹g

Number of moles:

Molar mass of H₂O = 2 + 16 = 18g/mol

Number of moles = $\frac{1 x 10^{-12} }{18}$ = 5.6 x 10⁻¹⁴moles

Number of molecules = 5.6 x 10⁻¹⁴ x 6.02 x 10²³ = 33.7 x 10⁹

= 3.37 x 10¹⁰ molecules
