Balance copper (II) sulphate + sodium hydroxide-> copper (II) hydroxide + sodium sulphate​

Chemistry
1 answer:
Eddi Din [679]2 years ago
7 0

Answer:

CuSO4 + 2NaOh -> CuOH2 + Na2SO4

Explanation:

The sulphate ion is basically an anion(negatively charged ion) with a charge of overall -2. The hydroxide ion is also an anion with a charge of overall -1. Copper ion is described as copper (II) meaning that it has a charge of +2. Sodium is an alkali metal meaning that it has a charge of +1.

Now we know that the end results are copper hydroxide and sodium sulphate. Since the copper ion has a charge of +2, two hydroxide ions should bond with copper. The sulphate ion has a charge of -2, meaning that two sodium ions should bond with sulphate. There should be two sodium ions to bond with one sulphate ion and two hydroxide ions to bond with one copper ion. Therefore, the coeffiecient for sodium hydroxide should be two.

Which of the following correctly represents the transmutation in which a curium-242 nucleus is bombarded with an alpha particle
Alekssandra [29.7K]

<u>Answer:</u> The chemical equation is written below.

<u>Explanation:</u>

Transmutation is defined as the process in which one chemical isotope gets converted to another chemical isotope. The number of protons or neutrons in the isotope gets changed.

The chemical equation for the reaction of curium-242 nucleus with alpha particle (helium nucleus) follows:

_{96}^{242}\textrm{Cm}+_4^2\textrm{He}\rightarrow _{98}^{245}\textrm{Cf}+_0^1\textrm{n}

The product formed in the nuclear reaction are californium-245 nucleus and a neutron particle.

Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should as
UNO [17]

Answer: 0.100 m K_2SO_4

Explanation:

Elevation in boiling point is given by:

\Delta T_b=i\times K_b\times m

\Delta T_b=T_b-T_b^0 = Elevation in boiling point

i= vant hoff factor

K_b = boiling point constant

m= molality

1. For 0.100 m K_2SO_{4}

K_2SO_4\rightarrow 2K^{+}+SO_4^{2-}  

, i= 3 as it is a electrolyte and dissociate to give 3 ions. and concentration of ions will be 3\times 0.100=0.300

2. For 0.100 m LiNO_3

LiNO_3\rightarrow Li^{+}+NO_3^{-}  

, i= 2 as it is a electrolyte and dissociate to give 2 ions, concentration of ions will be 2\times 0.100=0.200

3.  For 0.200 m C_2H_8O_3

, i= 1 as it is a non electrolyte and does not dissociate, concentration of ions will be 1\times 0.200=0.200

4. For 0.060 m Na_3PO_4

Na_3PO_4\rightarrow 3Na^{+}+PO_4^{3-}  

, i= 4 as it is a electrolyte and dissociate to give 4 ions. and concentration of ions will be 4\times 0.060=0.24m

Thus as concentration of solute is highest for K_2SO_4 , the elevation in boiling point is highest and thus has the highest boiling point.

How much energy is required to raise the temperature of 3kg of iron from 20 degrees Celsius to 25 degrees Celsius
Yuri [45]

Answer:

6750 J

Explanation:

The specific heat capacity of iron is 450 J/kg/K

Quantity of heat = mcθ; where m is the mass and c is the specific heat capacity and θ is the temperature change.

Therefore;

m = 3 kg, c = 450 J/kg/K and θ = 5°C

Quantity of heat = 3 × 450 × 5

                           <u>= 6150 Joules</u>
