PLEASE HELP! NO LINKS! CHEMISTRY!
Bingel [31]

Answer:

Solution A is 1,000 times more acidic than Sol. B

Explanation:

for pH values we use scientific notation:

-log10 c (where c is the hydrogen ion concentration) is used to notate pH value (think of it as a unit)

ie:

10^-2 is sol A 10^-5 is sol B

5-2 is 3

10^-3 = 1000

there's a diff of 1,000 between the solutions.

Once formed, how are coordinate covalent bonds different from other covalent bonds?
-Dominant- [34]

Answer:

\boxed {\boxed {\sf {One \ atom \ donates \ both \ electrons \ in \ a \ pair}}}

Explanation:

A covalent bond involves the sharing of electrons to make the atoms more stable, and so they satisfy the Octet Rule (8 valence electrons).

Typically each atom contributes an electron to form an electron pair. This is a single bond. There are also double bonds (two pairs of electrons), triple bonds (three pairs of electrons), and coordinate covalent bonds.

Sometimes, to satisfy the Octet Rule and achieve stability, one atom contributes both of the electrons in an electron pair. This is different from other covalent bonds because usually each of the 2 atoms contributes an electron to make a pair.

REALLY NEED HELP!!! Chemistry
kicyunya [14]

Answer:

C.) 2

Explanation:

The pH equation is:

pH = -log[H⁺]

In this equation, [H⁺] is the molarity of the acid. In this case, the acid is HCl. Molarity can be found using the equation:

Molarity (M) = moles / volume (L)

Since you were given moles and volume, you can find the molarity of HCl.

Molarity = moles / volume

Molarity = 0.01 moles / 1.00 L

Molarity = 0.01 M

Now, you can plug the molarity of the acid into the pH equation.

pH = -log[H⁺]

pH = -log[0.01]

pH = 2

18. Use the activity series to predict whether the following synthesis reaction will occur. Write the chemical equations for the
MAXImum [283]

<u>Answer:</u> The chemical reaction for the synthesis reaction is given below.

<u>Explanation:</u>

Synthesis reaction is defined as a chemical reaction in which two small chemical substances combine together to form a single compound. The general equation for this chemical reaction follows:

A+B\rightarrow AB

For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:

2Ca(s)+O_2(g)\rightarrow 2CaO(s)

By Stoichiometry,

2 moles of calcium element combines together with 1 mole of oxygen gas to produce 2 moles of calcium oxide.

Hence, the chemical equation for the reaction is given above.
