Answer:

C

Explanation:

Because NH3 has 8 valence electrons, and Hydrogen can only have 1 bond

Answer:

5.158 mol/L

Explanation:

To find the molarity, you need to use the formula:

Molarity (M) = moles / volume (L)

You have been grams sodium carbonate. You need to (1) convert grams Na₂CO₃ to moles (via molar mass), then (2) convert moles Na₂CO₃ to moles HCl (via mole-to-mole ratio from equation), then (3) convert mL to L (by dividing by 1,000), and then (4) use the molarity equation.

Steps 1 - 2:

2 HCl + 1 Na₂CO₃ ----> 2 NaCl + H₂O + CO₂

6.5287 g Na₂CO₃         1 mole            2 moles HCl
--------------------------  x  -------------  x  -------------------------  =  0.12318 mole HCl
                                      106 g           1 mole Na₂CO₃

Step 3:

23.88 mL / 1,000 = 0.02388 L

Step 4:

Molarity = moles / volume

Molarity = 0.12318 mole / 0.02388 L

Molarity = 5.158 mole/L

**mole/L is equal to M**

[tex]PO_4^{-3}[/tex] and [tex]NH^{4+}[/tex] are polyatomic anions composed of two or more atoms.

A polyatomic ion is an ion composed of two or more atoms. Examples: The hydroxide cation ([tex]OH^-[/tex]) and the phosphate cation ([tex]PO_4^{3-}[/tex]) are both polyatomic ions.

[tex]PO_4^{-3}[/tex] and [tex]NH^{4+}[/tex] are the polyatomic anions because both contain more than 1 atom.

Hence,[tex]PO_4{-3}[/tex] and [tex]NH^{4+}[/tex] are polyatomic anions composed of two or more atoms.

Explanation:

Electrolytic cell used electrical energy to do electrolysis.

Then by using oxidation and reduction ions produced it does produce chemical changes

Option A

The amount, in mL, of the concentrated acid required, would be 1.1875 mL

From the dilution equation:

m1v1=m2v2 where m1 and m2 = molarity before and after dilution, and v1 and v2 = volume before and after dilution.

m2 = 0.285M, m1 = 12.0M v2 = 50.0 mL

v1 = m2v2/m1 = 0.285x50/12 = 1.1875 mL

Thus, 1.1875 mL of the acid would be taken and diluted with water up to the 50 mL mark.

Kinetic energy in different forms occurred from the falling water that turned the generators at the dam to the hot air that was produced from your hair dryer this morning.

Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

Kinetic energy (water) to electric energy (dam) as the hydroelectric dam works.

Then, as the current travels from the plant to your crib, electric energy to heat energy (wire resistance).

Then, when you are using the dryer electric energy to heat energy (hot air) and sound energy (air particles vibrate due to the heat energy).
