Which of the following best describe the particles present in a 2.0 M aqueous solution of Al(NO3)3?2 M Al3+(aq) and 18 M NO3-(aq

zvonat [6]

Answer:

The correct answer is: 2M Al3+(aq) and 6 M NO3-(aq)

Explanation:

Step 1: Data given

2.0 M Al(NO3)3

Step 2:

Al(NO3)3 in water will dissociate as following:

Al(NO3)3 → Al^3+ + 3NO3^-

For 1 mol of Al(NO3)3 we will have 1 mol of Al^3+ and 3 moles of NO3^-

We know that the molarity of Al(NO3)3 = 2.0 M, this means 2.0 mol/ L

The mol ratio Al(NO3)3 and Al^3+ is 1:1 so the molarity of Al^3+ is<u> 2.0 M</u>

The mol ratio Al(NO3)3 and NO3^- is 1:3 so the molarity of NO3^- is<u> 6.0M</u>

The correct answer is: 2M Al3+(aq) and 6 M NO3-(aq)

Write a balanced chemical equation that describes an acid-base reaction that would allow you to determine the moles of aspirin p

Kryger [21]

A balanced equation representing the acid-base reaction that allows the calculation of the moles of aspirin in a sample is

$C_{9} H_{8}O_{4} + NaOH$ ⇒ $C_{9} H_{7}O_{4} Na+ H_{2} O$

Aspirin, also known as acetylsalicylic acid, is a nonsteroidal anti-inflammatory drug used to reduce pain, fever, and/or inflammation, and as an antithrombotic.

Aspirin is a benzoic acid with an ortho-substituted acylated alcohol function (actually a phenol). Therefore, two reactions can occur when aspirin and NaOH are combined: In fact, several aspirin formulations contain this ingredient.

Hence, A balanced equation representing the acid-base reaction that allows the calculation of the moles of aspirin in a sample is

$C_{9} H_{8}O_{4} + NaOH$ ⇒ $C_{9} H_{7}O_{4} Na+ H_{2} O$
