Answer:
Heat, Q = 3035.073 J
Explanation:
It is given that,
Mass of water, m = 15.5 g
Initial temperature, 
Final temperature, 
The specific heat of water is, c = 4.184 J/ g°C
The heat removed or absorbed by water is given by formula as :

So, the heat of 3035.073 J is removed from 15.5 g of water.
Answer:
Yes
Explanation:
All living things do have cells
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

Answer:
Positively or negatively charged (im not 100% sure but the question says "as they have lost or gained electrons") because atoms that gain electrons are called anions and atoms that lose electrons are called cations. atoms losing electrons are positively charged and atoms gaining electrons are negatively charged.
I'm not sure if this helps a lot but now you know a few things about ions :)
