Well, you could get the mass as

, where
is the sea level weight,
the sea level accel.,
the accel. above while
the weight above.
Iron (II) Acetate : Fe(C2H3O2)2
Light travels at precisely <span>299,792,458 metres every second (abbreviated to 3 x 10^8 metres every second but let's be precise)
There are 60 seconds in every minute (</span><span>299 792 458 x 60 = 17,987,547,480m)
60 minutes in every hour (17,987,547,480 x 60 = 1,079,252,849,000m)
96 hours in 4 days (</span><span>1,079,252,849,000 x 96 = 10,360,827,350,000m)
</span><span>Now let's convert to km to make this number (slightly) more manageable
(</span>10,360,827,350,000 / 1000 = <span>103,608,273,500km)
</span>Light travels <span>103,608,273,500km in 4 days - that's the equivalent of going around the equator of the earth 813,124 times!</span><span>

Answer:
Saponification is a process of mixing triglycerides with potassium hydroxide (lye) in order to produce fatty acid and glycerol also known as soap.
During this experiment, many errors can occurs which are following;
- Incorrect measurement of both the salts that combine to form soap.
- The beaker and the stirrer has residue of some other chemical that gets mixed with two components and reacts.
- The two products are not mixed well or not long enough to reach the end product.
- The temperature is not favorable.
- The resting period is not calculated properly
I hope the answer is helpful.
Answer: Option (a) is the correct answer.
Explanation:
According to thermodynamics, a closed system is defined as the system in which there will be no exchange of matter takes place but there will be exchange of energy between the system and surrounding.
On the other hand, an open system is defined as the system in which there will be exchange of both matter and energy takes place between system and surrounding.
Hence, we can conclude that out of the given options accurate descriptions of closed and open thermodynamic processes is that open processes are 'flow through' processes.
