Answer:

Boron Carbonate; B₂(CO₃)₃

Explanation:

For names, carbonide does not exist; that rules out the first option. Carbide refers to just a carbon atom, not carbon and oxygen as in the polyatomic ion carbonate. That rids us of the third option. We are left with boron carbonate with the formula BCO or boron carbonate with the formula B₂(CO₃)₃.

Recall the carbonate polyatomic ion's formula: CO₃²⁻

Thus BCO cannot be the formula.

Option 4 is your answer, Boron Carbonate; B₂(CO₃)₃.

To further check your answer, observe the oxidation states of boron and the polyatomic ion carbonate. Boron can exist in oxidation states of either 2+ or 3+, and carbonate is only 2-; in this formula, boron will exhibit a 3+ state to balance out with carbonate.

2x3+ = 6+; 3x2- = 6-

6+ + 6- = 0; balanced

I need help plss asap
Basile [38]

Answer:

Volume = mass/density

Rearrange the equation for Mass:

Mass = Volume x Density

That is one way you can do it

Conceptually, just look at the units, the wood block's density is 0.6<u>g/cm^3</u> while the volume is 2.2 <u>cm^3</u>

So if density is every gram per centimeter cubed, and the volume is at centimeter cubed, the logical thing to do would be to multiply the density by the volume to get the total mass.

0.6g/cm^3   x   2.2cm^3 = 1.32g

<u>Therefore the mass of the block of wood is 1.32g </u>

What is carbonic acid and how does it affect rock?
Vadim26 [7]
<span>Carbonic acid is a chemical compound with the chemical formula H₂CO₃. It is also a name sometimes given to solutions of carbon dioxide as it contains water. It affects the rock by a process. When water meets carbon-dioxide in the air, a weak solution occurs called "CARBONIC ACID" and when it meets the crack of the rock, it diffuses and it ti dissolve with it. HOPED THIS HELPS YOU :)</span>

Lina20 [59]

Answer: 0.08 M

Explanation:

\text{molarity}=\frac{\text{moles of solute}}{\text{liters of solution}}\\\\\text{molarity}=\frac{0.25}{3.00}\\\\\text{molarity}=\boxed{0.08 \text{ M}}
