Strong acids are assumed 100% dissociated in water. True As a solution becomes more basic, the pOH of the solution increases. Fa
Kruka [31]

Answer:

Strong acids are assumed 100% dissociated in water- True

As a solution becomes more basic, the pOH of the solution increases- false

The conjugate base of a weak acid is a strong base- true

The Ka equilibrium constant always refers to the reaction of an acid with water to produce the conjugate base of the acid and the hydronium ion- True

As the Kb value for a base increases, base strength increases- true

The weaker the acid, the stronger the conjugate base- true

Explanation:

An acid is regarded as a strong acid if it attains 100% or complete dissociation in water.

The pOH decreases as a solution becomes more basic (as OH^- concentration increases).

Ka refers to the dissociation of an acid HA into H3O^+ and A^-.

The greater the base dissociation constant, the greater the base strength.

The weaker an acid is, the stronger , its conjugate base will be.

What type of map projection makes plotting travel by airplane the easiest? I know it's azimuthal maps but why
KatRina [158]

Answer:

Explanation:

Azimuthal maps projection is the easiest for plotting travel by airplane because Azimuthal maps make the UV plane to be tangent to the globe and it's make the directions from the center of projections to be correct and accurate to any other points , likewise circles are also projected directly to the straight lines on the plane. And this is because Any line that is normally drawn through the tangent point give distance correctly and accurately.

“Na2SO3” represents sodium sulfite.What does the 4 mean in the formula 4Na2SO3?
Strike441 [17]

The mass of substance which consists the equal number of particles as 12 grams of Carbon-12 is said to be mole.

For example:

The balanced chemical equation for production of water from hydrogen and oxygen is:

2H_2(g) + O_2(g) \rightarrow 2H_2O(l)

That means 2 moles of H_2 reacts with 1 mole of O_2 to give 2 moles of  H_2O.

The given formula is 4Na_2SO_3.

Hence, 4 represents the number of moles in 4Na_2SO_3 formula that is 4 moles of Na_2SO_3.

The number of atoms of sodium, Na in 4Na_2SO_3 is:

4 \times 2 = 8

The number of atoms of sulfur, S in 4Na_2SO_3 is:

4 \times 1 = 4

The number of atoms of oxygen in, O in 4Na_2SO_3 is:

4 \times 3 = 12
