A rectangular prism of volume 84 cm3 has a mass of 760 g. What is the density of the rectangular prism?
2 answers:
Answer : The density of the rectangular prism is, 9.05 g/ml.
Explanation :
Density : It is defined as the mass contained per unit volume.
Formula used :
Given :
Mass of rectangular prism = 760 grams
Volume of rectangular prism =
Now put all the given values in the above formula, we get:
Thus density of the rectangular prism is, 9.05 g/ml.

Answer 1:
Consider reaction: <span>Ni^2+ (aq) + S^2- (aq) ----> + Ni (s) + S (s)
The cell representation of above reaction is given by;
</span>
Hence,
we know that,
and
Therefore,
= - 0.25 - (-0.47) = 0.22 v
Since, is positive, hence cell reaction is spontaneous

Answer 2:
Consider reaction: <span>Pb^2+ (aq) +H2 (g) ----> Pb (s) +2H^+ (aq)
</span>
The cell representation of above reaction is given by;
Hence,
we know that,
and
Therefore, = - 0.126 - 0 = -0.126 v
Since, is negative, hence cell reaction is non-spontaneous.
