Answer:

Option C. K⁺(aq) and SO₄²¯(aq)

Explanation:

We'll begin by writing the ionic equation between H₂SO₄ and KOH.

This is illustrated below:

In solution, H₂SO₄ and KOH will dissociate as follow

H₂SO₄ (aq) —> 2H⁺ (aq) + SO₄²¯ (aq)

KOH (aq) —> K⁺ (aq) + OH¯ (aq)

Thus, aqueous H₂SO₄ and KOH will react as follow:

H₂SO₄ (aq) + 2KOH (aq) —> K₂SO₄ (aq) + 2H₂O (l)

Ionically:

2H⁺(aq) + SO₄²¯(aq) + 2K⁺(aq) + 2OH¯(aq) —> 2K⁺(aq) + SO₄²¯(aq) + 2H₂O (l)

The spectator ions are those ions that appear on both sides of the equation.

From the above ionic equation, the spectator ions are:

K⁺(aq) and SO₄²¯(aq)

Describe the major advantages and disadvantages of asexual and sexual reproduction.

Fynjy0 [20]

Answer:

Allows for a quick "doubling of population because they skip pollination and fertilisation. There is less energy required for asexual reproduction. Large colonies can form that out complete the other organisms for nutrients and water. ... Sexual reproduction leads to genetic variation in new generations of offspring.

if I add 1.50 L of water to 250 mL of a 12.5 M NaOH solution, what will the molarity of the diluted solution be?

Fantom [35]

Answer:

The molarity of the diluted solution is 1.786 M

Explanation:

Dilution is a process in which you always start with a concentrated solution to which a greater volume of solvent is added. This modifies the concentration and volume of the resulting solution, but the amount of solute used to prepare the initial solution remains the same.

In summary, in a dilution the amount of solute does not vary, but the volume of the solvent varies: when more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

The following rule is fulfilled:

Vinicial x Cinicial = Vfinal x Cfinal

where:

Vinicial = Initial volume.
Cinicial = Initial concentration
Vfinal = Final volume
Cfinal = Final concentration

In this case:

Vinicial= 250 mL= 0.25 L (Being 1 L=1000 mL)
Cinicial= 12.5 M
Vfinal= 1.5 L+ 0.25 L=1.75 L
Cfinal= ?

Replacing:

0.25 L* 12.5 M= 1.75 L* Cfinal

Solving:

$Cfinal=\frac{0.25 L* 12.5 M}{1.75 L}$

Cfinal= 1.786 M

The molarity of the diluted solution is 1.786 M

How are the functions of ribosome, Golgi bodies, and endoplasmic related?

mihalych1998 [28]

all 3 are related to each other through their involvement in protein synthesis and transport.

Ribosomes are the sites of protein synthesis and carry out this work by assembling the amino acids in the appropriate sequence, as dictated by the mRNA (messenger RNA).

These cell organelles are most commonly found embedded in the endoplasmic reticulum. Large scale protein synthesis is possible due to the very large surface area offered by the endoplasmic reticulum to the ribosomes.

The main function of the endoplasmic reticulum is to transport the newly synthesized proteins over to the Golgi apparatus. The primary role of the Golgi apparatus is to modify the proteins and encase them into vesicles. From here they are transported to the various parts of the cell.

this is why it's the answer!
