Answer:

180 g

Explanation:

At the end of the reaction, the mass is still expected to be 180g this is because in every chemical reaction, mass must be conserved.

According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".

  • Bonds are broken and elements rearranged.
  • The mass is thereby constant
  • The sum of the mass of the reactant is then even equal to the mass of the product derived.

The equilibrium constant of the reaction is 1.21 * 10^6 while the change in free energy is -34.7 kJ.

<h3>What is equilirium constant?</h3>

The equilibrium constant shows the extent of conversion of reactants to products.

Now we know from the Nernst equation that;

Ecell = E°cell - 0.0592/n logQ

E°cell = 0.52−0.16=0.36 V

Since Ecell = 0 V at equilibrium,

0 = 0.36 - 0.0592/1 log K

0.36  = 0.0592/1 log K

log K = 0.36/ 0.0592

K = antiog (0.36/ 0.0592)

K = 1.21 * 10^6

ΔG = -RT lnK

ΔG =-(8.314 * 298 * ln1.21 * 10^6)

ΔG =-34.7 kJ

When water droplets become large enough in a cloud, it can lead to
I am Lyosha [343]

Answer:

Rain

Explanation:

When small water droplets combine to form larger water droplets, the density of the water droplet increased to a point that is much denser than the atmospheric air. Due to gravity, the large water droplet falls as rain.

Shtirlitz [24]
Mass/moles x mr
so you need to work out the rfm of Ca(OH)2= 40(16+1)2= 40+34= 74
and then use the formula= moles x mr
6.25 x 74= 462.5
