The arrow that represents the transition in which dew is formed would be arrow 4.

<h3>How is dew formed?</h3>

Dew is formed by condensation. Condensation, in itself, involves a transition from a gas phase to a liquid phase.

From the diagram, the arrow that represents a transition from gas to liquid is arrow 4.

Thus, the arrow that represents the transition that leads to the formation of dew would be arrow 4.

Hydrogen bonding occurs in molecules when a _____________. (1 point)

Burka [1]

Answer: hydrogen atom of a polarized molecule bonds with an electro negative atom.

Explanation:

Hydrogen bonds are special type of dipole dipole forces which are formed when hydrogen bonds with an electro negative element. Hydrogen bonds are strongest type of bonds .Example: Bond between Oxygen of one water molecule to the hydrogen of another water molecule as shown in the image below.

Covalent bonds are formed by sharing of electrons among non metals.

Ionic bond is formed by transfer of electrons between metals and non metals.

) The reaction below is exothermic: 2SO2 (g) O2 (g) 2SO3 (g) Le Cha^ telier's Principle predicts that __________ will result in

Lynna [10]

Answer:

A) increasing the pressure

Explanation:

Given the exothermic reaction:

2SO₂(g) + O₂(g) ↔ 2SO₃(g)

the question asks what will make the number of moles of SO₃(g) to increase.

When an equilibrium is disturbed, the system will shift in order to counteract the change (see <em>Le Chatelier's Principle</em>) So <em>when the pressure is increased in a reaction involving gases, the equilibrium will shift trying to decrease the number of moles </em>(because pressure is produced by molecules hitting the container), that is in this case it will shift towards the right side, towards the production of SO₃, thus increasing the number of moles of SO₃.

The number of moles in the right side is 2 and the number of moles in the left side is 3.

How many grams of water are needed to react with 18.9 grams of li2o? given: li2o+h2oâ2lioh?

4vir4ik [10]

The balanced equation for the reaction is as follows;
Li₂O + H₂O ---> 2LiOH
Stoichiometry of Li₂O to H₂O is 1:1
Mass of Li₂O reacted - 18.9 g
Number of Li₂O moles reacted - 18.9 g / 30 g/mol = 0.63 mol
An equivalent amount of moles of water have reacted - 0.63 mol
mass of water required - 0.63 mol x 18 g/mol = 11.34 g
A mass of 11.34 g of water is required

(CH3)2-CH-CH2-O(CH3)3IUPAC NAME

bazaltina [42]

Answer:

1-(tert-butoxy)-2-methylpropane

Note: there is a mistake in formula, the correct formula is (CH₃)₂-CH-CH₂-O-C(CH₃)₃ not (CH₃)₂-CH-CH₂-O(CH₃)₃, because oxygen is a divalent compound.

Explanation:

<em>Structural formula is attached</em>

IUPAC naming rules

1. start numbering the chain from the functional group. In this compound we start from oxygen side.

2. Here we can see that at position 1 there is an oxy group along with a tertiary carbon having three methyl groups. So we write it as 1-tert-butoxy. Which means that there is a methoxy group at position 1 along with a tertiary carbon.

3. At position 2 we can see that there is a methyl group attached to the main chain, so we write it as 2-methyl.

4. Now we count the total number of carbons in the main chain. As we can see that there are 3 carbons in the remaining or parent chain, so we write it as propane

5. So the IUPAC name of the compound will be 1-(tert-butoxy)-2-methylpropane
