Only the second 2Fe + Al2O3 = 2Al + Fe2O3. In the first reaction iodide can not replace bromide from the salt. In the third reaction lead can not replace more active zinc metal from the salt.

Answer:  2AgNO3+Ni\rightarrow Ni(NO_3)_2+2Ag

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

1) 2NaBr+I_2\rightarrow 2NaI+Br_2

As iodine is less reactive than bromine, it will not be able to displace bromine from its salt solution, hence no reaction will occur.

2)2Fe+Al_2O_3\rightarrow 2Al+Fe_2O_3

As iron lies lower in reactivity series, it is less reactive than Aluminium. It will not be able to displace aluminium from its salt and hence no reaction occur.

3) 2AgNO3+Ni\rightarrow Ni(NO_3)_2+2Ag

As nickel lies above in reactivity series, it is more reactive than silver. It will be able to displace silver from its salt and hence reaction will occur.

4) Pb+Zn(C_2H_3O_2)_2\rightarrow Zn+Pb(C_2H_3O_2)_2

As lead lies lower in reactivity series, it is less reactive than zinc. It will not be able to displace zinc from its salt and hence no reaction occur.

What does the sun do to generate energy?
Kruka [31]
Within the core of the Sun, temperatures and pressures are high enough to fuse hydrogen atoms into helium, which is the Sun's main form of energy production. Assuming there was a slight mistake in where you have copied the results here the correct answer is the third option.
Hope this helps!

Convert a density of 7.2 g/ml into the unit kg/L
aivan3 [116]

Unit conversion is a multi-step process, in which division or multiplication by a numeral factor is involved.

Density = 7.2 g/mL    (given)

Since, 1 g = 0.001 kg and

1 mL = 0.001 L

Now, converting 7.2 g/mL to kg/L:

7.2 \frac{g}{mL}\times \frac{1 kg}{1000 g}\times \frac{1000 mL}{1 L}

= 7.2 kg/L.

Hence, density is 7.2 kg/L.

What causes the Brownian motion of particles in a colloid?
LekaFEV [45]

<u>Answer:</u>

The correct answer option is a) collisions between the particles and surrounding molecules.

<u>Explanation:</u>

The collisions between the particles and surrounding molecules causes the Brownian motion of particles in a colloid.

Brownian motion is the irregular movement of the microscopic particles in a fluid which bombard into each other.

It basically is the result of the molecules of a dispersion medium colliding with the dispersed particles of the phase.
