The molecules will always move from areas of higher concentration to areas of lower concentration when you are talking about diffusion.

The solution always want to be balanced, so if you have more, let’s say salt inside the cell, then the salt will flow through the membrane to the outer less salty solution until the salt level both inside and out the cell are equal.

Analyze the diagram showing the changing states of matter. Drag the item from the item bank to its corresponding match.

iVinArrow [24]

The correct matches for changes of state are:

1 or 3 : Arrow that shows particles getting closer together
gas: State of matter that would fill any container
liquid: State of matter with definite volume but NOT shape
2 or 4: Arrow that shows particles gaining energy
solid: State of matter with definite shape

<h3>What is change of state?</h3>

Change of state is the process whereby matter in one physical state is converted to matter in another state by the addition or removal of heat.

The process of change of state are:

Melting: solid to liquid due to addition of heat
Vaporization: liquid to gas due to addition of heat
Sublimation: solid to gas due to addition of heat
Freezing: liquid to solid due to removal of heat
Condensation: gas to liquid due to removal of heat
Deposition: gas to solid due to removal of heat

Considering the given diagram, the correct matches are:

1 or 3 : Arrow that shows particles getting closer together
gas: State of matter that would fill any container
liquid: State of matter with definite volume but NOT shape
2 or 4: Arrow that shows particles gaining energy
solid: State of matter with definite shape

In conclusion, change of state of matter occurs due to heat changes.

Of the choices below, which is true for the relationship shown? It is Ka for the acid H3P2O72−. It is Kb for the acid H3P2O72−.

Naily [24]

The expression for the Ka for the given acid is:

Ka = [H2P2O7^2-] [H3O+] /[H3P2O7^2-]

<span>Ka is the acid dissociation constant or the acidity constant. It is a measure of the acid strength when in solution. It is an equilibrium constant for the dissociation of the acid.</span>

How many grams are in 4.3 x 10 -4 moles of calcium phosphate?

attashe74 [19]

Explanation:

Ca3(PO4)2 1 mole has 310.2 g

Ca3(PO4)2 4.3 × 10^-4 moles has 4.3 × 10^-4 × 310.2

= 1,333.86 × 10^-4

= 1.334 × 10^-1

OR 0.1334 g
