Answer:

Matter in its solid state has the lowest amount of thermal energy (for that type of matter). Because solids have less thermal energy than liquids or gasses, the atoms in their solid state move very little.

The mass of a present which has a density of 2.15 kg/L and volume of 3650 mL is 7.74 kg.

<h3>How do we calculate mass?</h3>

Mass of any substance will be calculate by using the density and volume by using the below equation as:

Density = Mass / Volume

Given that,

Density of Christmas present = 2.15 kg/L

Volume of present = 3,650 mL = 3.6L

On putting values, we get

Mass = (2.15)(3.6) = 7.74

Hence required mass of Christmas present is 7.74 kg.

1. double replacement[two of the chemical species(B and D)exchanged positions]

2. Combustion(the reaction with oxygen produced CO2 and water; products of Combustion)

3. Single replacement(only one chemical specie[B] exchanged position)

4. Combination(the two reactants formed a single product)

5. Decomposition(a compound released two constituent products)

6. 1PbCl2 + 2AgNO3 = 1Pb(NO3)2 + 2AgCl. it is a double replacement reaction since two chemical species(Chlorine(Cl) and Nitrogen(iii)oxide[NO3]) exchanged positions.

7. 1NH3 + HCL = NH4Cl. it is a combination reaction since two reactants formed a single product.

8. 2AlCl3 + 3Na2SO4 = 1Al(SO4)3 + 6NaCl. it is a double replacement reaction since two chemical species(chlorine[Cl] and sulphate[SO4]) exchanged positions.

9. 1Zn + 1S = 1ZnS. it is a combination reaction since two reactants formed a single product.

10. 1Al2(SO4)3 + 3BACl2 = 3BASO4 + 2ALCL3. it is a double replacement reaction since two chemical species(chlorine[Cl] and sulphate[SO4]) exchanged positions.

11. 1Al2S3 = 2Al + 3S. it is a decomposition reaction since a reactant released two constituent products.

12. 1H2SO4 + 1Fe = 1H2 + 1FeSO4. it is a single replacement reaction since one chemical specie(sulphate[SO4]) exchanged position.

13. C12H22O11 + 12O2 = 12CO2 + 11H2O. it is a combustion reaction since a reactant combined with oxygen to release carbon dioxide(CO2) and water(H2O).

14. 1Mg(OH)2 + 1H2SO4 = 1MgSO4 + 2H2O. it is a double replacement reaction since two chemical species(hydroxide[OH] and sulphate[SO4]) exchanged positions.

15. 2NaOH + 1CuSO4 = Na2SO4 + Cu(OH)2. it is a double replacement reaction since two chemical species(hydroxide[OH] and sulphate[SO4]) exchanged positions.

16. 1C4H12 + 7O2 = 6H2O + 4CO2. it is a combustion reaction since a reactant combined with oxygen to release carbon dioxide(CO2) and water(H2O).

Determine if each compound shown is soluble or insoluble. cu(oh)2

vredina [299]

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.
