Amount of money that Cheryl has = $56
Cost of each notebook = $1.60
The maximum number of notebooks she can buy = n
Then

n = 56/1.6 

is the inequality that shows the maximum number of notebooks she can buy with her money

On solving the inequality, we get
n = 35 notebooks.

A correct statement of Henry's law is: a. The concentration of a gas in solution is inversely proportional to temperature. b. Th
AVprozaik [17]

Answer:

e. None of these.

Explanation:

Hey there!

In this case, since the Henry's law is defined in terms of pressure, henry's constant and pressure, as shown below:

C=K_H*P

Whereas C is the concentration, KH the Henry's constant and P the pressure, we infer that the concentration of a gas solution is directly proportional to the pressure, which is not the group choices, therefore, the answer is e. None of these.

Best regards!

1. An acid will have the suffix “–ic acid” at the end of its name when the negative
Nimfa-mama [501]
  • An acid will have the suffix “–ic acid” at the end of its name when the negative ion has a suffix -ide.
  • An acid will have the suffix “–ous acid” at the end of its name when the negative ion has a suffix -ite.

<h3>What is an Acid?</h3>

This is defined as a chemical substance which can react with a base to form a salt in a reaction.

The appropriate acid suffixes and conditions is however correctly given above.

State the type of bonding—ionic, covalent, or metallic—you would expect in each:<br> (b) MgCl₂(s);
IceJOKER [234]

MgCl2 is an ionic compound because chemical bonds in the molecule are formed by the transfer of electrons among Mg and Cl atoms.

<h3>What is chemical bond ?</h3>

A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds. Covalent, ionic, and metallic bindings are examples of "strong bonds" or "primary bonds," whereas dipole-dipole interactions, the London dispersion force, and hydrogen bonding are examples of "weak bonds" or "secondary bonds."

The positively charged protons in the nucleus and the negatively charged electrons in its orbit are attracted to one another by the basic electromagnetic force.

It takes 60 mL of 0.20 M of sodium hydroxide (NaOH) to neutralize 25 mL of carbonic acid (H2CO3) for the following chemical reac
irina1246 [14]

If It takes 60mL of 0.20M of sodium hydroxide (NaOH) to neutralize 25 mL of carbonic acid (H_2CO_3), then the concentration of the carbonic acid is 0.24M

The reaction between NaOH solution and H_2CO_3 is written below

2NaOH + H_2CO_3 \rightarrow Na_2CO_3 + 2H_2O

Volume of NaOH, V_B = 60 ml

Volume of H_2CO_3, V_A=25 ml

Molarity of H_2CO_3, C_A=?

Molarity of NaOH, C_B=0.20M

Number of moles of H_2CO_3, n_A=1

Number of moles of NaOH, n_B=2

The mathematical equation for neutralization reaction is:

\frac{C_AV_A}{C_BV_B} =\frac{n_A}{n_B}

Substitute  C_B=0.2 M,  n_A=1,  n_B=2,  V_B = 60ml, and  V_A=25 ml into the equation above in order to solve for C_A

\frac{C_A \times 25}{0.2 \times 60}=\frac{1}{2}  \\\\50C_A=12\\\\C_B=\frac{12}{50} \\\\C_B=0.24M

Therefore, the concentration of the carbonic acid is 0.24M
