This is because absorbed heat energy or released by water is dependent on mass of water.
q=mc delta T
where q is the amount of energy required, m is the mass , C is the specific heat capacity and delta T is change in temperature.
It indicates how fast reactants become products.
Answer:
Silicon forms four covalent bonds with hydrogen. The formula of the compound is SiH4. Germanium forms four covalent bonds with chlorine, the formula of the compound is GeCl4
Explanation:
The outermost shell of group 14 elements contains four electrons, which can combine with four other atoms having one unpaired electron in their outermost shell to form four electron pairs or a complete octet as required by the octet rule.
<u>Answer:</u> The predicted cell potential of the cell is +0.0587 V
<u>Explanation:</u>
The half reactions for the cell is:
<u>Oxidation half reaction (anode):</u> 
<u>Reduction half reaction (cathode):</u> 
In this case, the cathode and anode both are same. So,
will be equal to zero.
To calculate cell potential of the cell, we use the equation given by Nernst, which is:
![E_{cell}=E^o_{cell}-\frac{0.0592}{n}\log \frac{[M^{2+}_{(diluted)}]}{[M^{2+}_{(concentrated)}]}](https://tex.z-dn.net/?f=E_%7Bcell%7D%3DE%5Eo_%7Bcell%7D-%5Cfrac%7B0.0592%7D%7Bn%7D%5Clog%20%5Cfrac%7B%5BM%5E%7B2%2B%7D_%7B%28diluted%29%7D%5D%7D%7B%5BM%5E%7B2%2B%7D_%7B%28concentrated%29%7D%5D%7D)
where,
n = number of electrons in oxidation-reduction reaction = 2
= ?
= 0.05 M
= 4.808 M
Putting values in above equation, we get:


Hence, the predicted cell potential of the cell is +0.0587 V
