Answer:
the answer is b,the answer has to be even though I'm not very sure about it
In thermodynamics, work of a system at constant pressure conditions is equal to the product of the pressure and the change in volume. It is expressed as follows:
W = P(V2 - V1)
W = 1.3x10^5 (2x6 - 6 )
W = 780000 J
Hope this answers the question. Have a nice day.
Oxidation is loss of electrons from a substance, and Reduction is gain of electrons by a substance.
These two processes cannot occur without the other. If there is a reduction there must be an oxidation reaction and vice versa. The reactions usually occur simultaneously.
For example, table salt is formed by a redox reaction. Sodium is oxidized i.e. loses an electron (and becomes positively charged) while chlorine gas is reduced i.e. gains the electron (and become negatively charged). The result is formation of sodium chloride.
Mass = molecular mass x mol
mass = 176.128 x 0.000142
mass = 0.025 g (3 s.f)
B. New atoms are formed as products.
