H: Cytoplasm
E: Lysosome
F: Mitochondria
A: Centriole
G: Endoplasmic reticulum
?: Vacuole
D: Cell membrane
J: Nucleus
L: Ribosome
C: Nuclear membrane
B: Golgi apparatus
K: Vesicle
I: Nucleolus

There is no function/description that accurately matches up with the vacuole. In fact, there are 13 organelles provided and only 12 functions/descriptions listed; presumably, the description/function of the vacuole is the one that is missing.

Consider the incomplete structure. Add formal charges as necessary to the structure. All unshared valence electrons are shown.

Zina [86]

The net charge on the structure as shown in the question is -1.

<h3>What is a charged specie?</h3>

We say that a specie is charged if the specie has an excess of positive or negative charge. An excess of the positive charge means that the substance is positively charged while an excess if the negative charge simply means that the object is negative charged.

When we have a chemical structure as we have seen, it is possible that the structure as we have it could have a net charge. The net charge that the structure has can be deduced by looking at the formal charges that are carried by all the atoms that we have in the system.

The charge as we can see that is on the central atom of the molecule is the -1 charge hence this is the charge that is carried overall by the molecule.

If we then look at the structure as we can see, we can see that there is a charge of negative one that is attached to the atom of chlorine as is clearly visible and obvious from the image attached to the question.

Alisiya [41]

Answer:

613.0 g

Explanation:

2 L = 2000 mL

Write a balanced net ionic equation showing only the particles involved in the reaction and balancing the charges.Pb(s) AgNO3aq)

Alexus [3.1K]

Answer:

Pb(s) + 2Ag+(aq) → 2Ag(s) + Pb2+(aq)

Explanation:

Step 1: The unbalanced equation

Pb(s) + AgNO3aq) → Ag(s) + Pb(NO3)2(aq)

Step 2: Balancing the equation

Pb(s) + AgNO3aq) → Ag(s) + Pb(NO3)2(aq)

On the right side we have 2x NO3, on the left side we have 1x NO3.

To balance the amount of NO3 on both sides, we have to multiply AgNO3 (on the left side) by 2.

Pb(s) + 2AgNO3aq) → Ag(s) + Pb(NO3)2(aq)

On the left side we have 2x Ag, on the right side we have 1x Ag.

To balance the amount of Ag on both sides, we have to multiply Ag (on the right side) by 2. Now the equation is balanced.

Pb(s) + 2AgNO3(aq) → 2Ag(s) + Pb(NO3)2(aq)

The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will look like this

Pb(s) + 2Ag+(aq) → 2Ag(s) + Pb2+
