Chemistry

vredina [299]3 years ago
4 0

We have to determine if the given compound is soluble or insoluble in water.

The given compound is copper (II) hydroxide, Cu(OH)_{2}. According to the solubility rules the hydroxides of all metal ions are insoluble except that of ammonium and the alkali metal ions. So copper(II) hydroxide will be insoluble in water. In aqueous solution, copper (II) hydroxide would exist as a sparingly soluble compound in which the undissociated compound remains in equilibrium with the ions Cu^{2+}and OH^{-}. The equilibrium would remain mostly towards undissociated form.

Cu(OH)_{2}(s)Cu^{2+}(aq)+2OH^{-}(aq)

Therefore, Cu(OH)_{2}is insoluble in water.

How many significant digits will the answer in the following calculations result in?
Reil [10]

Answer:

The answer will result in one significant digit.

Explanation:

1. Subtract:

     12.1 - 12.004 = 0.096

2. ROund to the correct number of significant digits:

      For addition and subtraction we round the sum or the difference to the least number of digits after the decimal point there are in the problem.  

      For example, SInce 12.1 has one number after the decimal point and 12.004 has three numbers after the decimal point, we round the answer to one number after the decimal point because 12.1 is the number in the problem which has the least amount of digits after the decimal point.

     We round 0.096 to 0.1.

     0.1 has one significant digit.

A volatile organic liquid with known molecular weight is added to a vapor density flask which has a known volume. The flask is h
kakasveta [241]

Answer: Mass of the condensed vapor is 21.35 grams.

Explanation: As a gas, the Ideal Gas Law can be used to determine how many mols there are in the flask on the conditions described in question.

Temperature in K: 273 + 99.3 = 372.4K

Pressure in mmHg: P = 760.5 mmHg

Volume in L: V = 496.3.10^{-3} = 0.5 L

Universal Constant of Gases in mmHg: R = 62.36 L.mmHg.K⁻¹.mol⁻¹

PV = nRT

n = \frac{PV}{RT}

n = \frac{760.5.0.5}{62.36.372.4}

n = 0.1625

To determine the mass in grams:

n = \frac{m}{M}

m = nM

m = 0.1625.131.4

m = 21.35

On the conditions cited above, there are <u>21.35 grams</u> of the unknown condensed vapor

The amount of the product in grams, formed from the limiting reactant is the _____________
artcher [175]

The amount of the product in grams, formed from the limiting reactant is the  theoretical yield

<u>Explanation:</u>

In a chemical reaction when the limiting agent is completely reacted and the product obtained is termed as Theoretical yield. The amount of product yield that is attained through a complete reaction of the limiting agent is the theoretical yield.  Grams or moles is used for expressing theoretical yield.

This is calculated form the limiting agent in a complete chemical reaction which is balanced.  If a chemical reaction is unbalanced, it should be first balanced to find the theoretical yield. Then, the limiting agent must be found. When the limiting agent is small in quantity, the reaction cannot be completed once the limiting agent is fully used and exhausted.
