Elden [556K]

Answer:

When copper(II) chloride and sodium carbonate solutions are combined, solid copper(II) carbonate precipitates, leaving a solution of sodium chloride. Write the conventional equation, total ionic equation, and net ionic equation for this reaction.

Explanation:

The word equation for the reaction is:

Copper (II) chloride(aq) + sodium carbonate (aq) ->sodium chloride (aq) + copper carbonate(s)

The balanced chemical equation of the reaction is:

$CuCl_2(aq)+Na_2CO_3(aq)->2NaCl(aq)+CuCO_3(s)$

The complete ionic equation is:

$Cu^2+(aq)+2Cl^-(aq)+2Na^+(aq)+CO_3^2^-(aq)->2Cl^-(aq)+2Na^+(aq)+CuCO_3(s)\\$

The net ionic equation is obtained from the complete ionic equation after removing the spectator ions:

$Cu^2^+(aq)+CO_3^2^-(aq)->CuCO_3(s)$

How many liters of the antifreeze ethylene glycol [CH2(OH)CH2(OH)] would you add to a car radiator containing 6.50 L of water if

liubo4ka [24]

Answer: 2.04L

Explanation:

coldest temperature = -10°C

mass of solvent = 6.50kg

freezing point depression = kb*m

Where kb = molar freezing point depression constant, 1.86

10 = 1.86 * molality of ethylene glycol

10 = 1.86 * moles of ethylene glycol/mass of solvent

10 = 1.86 * moles of ethylene glycol/6.5

10*6.5 = 1.86 * moles of ethylene glycol

Moles of ethylene glycol = 65/1.86

Moles of ethylene glycol = 36.11

36.11 mol * 62.1 g/mol = 2242.43g = 2.24kg

1 L = 1000 mL x 1.11 g/mL = 1100 g = 1.1 kg

2.24 kg / 1.10 kg/L = 2.04 L

How to prepared sodium chloride solution.

nexus9112 [7]

Explanation:

Dissolve 93.52g of NaCl in about 400mL of distilled water, then add more water until final volume is 800mL. If starting with a solution or liquid reagent: When diluting more concentrated solutions, decide what volume(V2) and molarity (M2) the final soluble should be.

If the density of chloroform is 1.5 g/cm³, what is the mass of 50.0 cm³ of chloroform?

Marianna [84]

Density = mass / volume

1.5 = m / 50.0

m = 1.5 x 50.0

m = 75 g

hope this helps!
