Explanation:

According to Arrhenius, acids are the species that readily dissociate into hydrogen or hydronium ions when dissolved in water.

For example, HCl + H_{2}O \rightarrow H_{3}O^{+} + Cl^{-}

On the other hand, Arrhenius bases are the species that readily dissociate to give hydroxide ions in water.

For example, KOH \rightarrow K^{+} + OH^{-}

Hence, we can conclude that Arrhenius acid is the term that gives the behavior of substance that is dissolved in water and produces hydronium ions.

Silver can be electroplated at the cathode of an electrolysis cell by the half-reaction. Ag+(aq)+e−→Ag(s) Part A Silver can be e
dmitriy555 [2]

Answer: Mass of silver deposited at the cathode is 37.1g

Explanation: According to Faraday Law of Electrolysis, the mass of substance deposited at the electrode (cathode or anode) is directly proportional to quantity of electricity passed through the electrolyte

Faraday has found that to liberate one gm eq. of substance from an electrolyte, 96500C of electricity is required.

Ag^+ +e− ==> Ag(s)

Given that

Current (I) = 8.5A

Time (t) = 65 *60 = 3900s

Quantity of electricity passed = 8.5*3900 =33150C

Molar mass of Ag= 108g

96500C will liberate 108g

33150C will liberate Xg

Xg= (108*33150)/96500

=37.1g

Therefore the mass of Ag deposited at the cathode is 37.1g.

Be sure to answer all parts.
djyliett [7]

The number of moles contained in each of the question are a) 3.935 and b) 0.001165 mol.

<h3>What are moles?</h3>

Moles are a quantity or amount of a substance. Denoted by n.

To calculate moles, mass is divided by the molar mass

n = m/M

mass is divided by the molar mass

a) 230 grams of NaCl

n = m/M

molar mass of NaCl is 58.44 g/mol

n = 230 / 58.44 = 3.935 mol

b) 0.210 g of aspirin

n = m/M

molar mass of aspirin is 180.158 g/mol

n = 0.210 / 180.158 = 0.001165 mol

Thus, the moles are a) 3.935 and b) 0.001165 mol.

charle [14.2K]

Answer:

1.059 x 10^24 formula units

Explanation:

103/58.44 = 1.76 moles NaCl

1.76 x 6.022 x 10^23 = 1.059 x 10^24

In 200 g of a concentrated solution of 70.4 wt% nitric acid (r = 1.41 g/mL, FW(HNO3) = 63.01 g/mol), how many grams of water are
mars1129 [50]

Answer:

59.2 grams

Explanation:

We are given that 70.4% of the weight of the total 200 g of the concentration is made up of nitric acid, the remaining information is not required to solve the problem. Since water and nitric acid are the only components of the solution, the total weight of water is given by:

W = 200*(1-0.704)\\W=59.2\ g

There are 59.2 grams of water in this solution.
