Answer:
Dead bodies lose one degree Celsius per hour, which we could deduce that the person died 12 hours ago.
Explanation:
On the other hand, it is very important to take into account that this number of hours is very approximate, since not only does it vary greatly with the environment and the acclimatization of the environment in which the person dies, but also in this specific case, insulating clothing was presented , which made the loss of body heat much more difficult and could easily be more than 12 hours.
The minimum for this particular situation is 12 hours to 24 hours possible postmortem.
It would be useful to memorize that sentence. Once you know that, you can figure out whatever else happens at the anode, the cathode, in the solution, and in the external circuit
Answer:In regards to writing the formula, we know that magnesium has a charge of 1+ and sulfate, SO4, has a charge of 1-. Sulfate is a polyatomic ion so the charge of the whole thing is (SO4)1-. When you combine them you end up with MgSO4 and the "heptahydrate" is seven water molecules.
Explanation:
Answer:
The specific heat capacity of quartz is 0.71 J/g°C.
Explanation:
Heat lost by quartz will be equal to heat gained by the water
Mass of quartz= 
Specific heat capacity of quartz= 
Initial temperature of the quartz= 
Final temperature = 
Mass of water=
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water = 
On substituting all values:
we get:
The specific heat capacity of quartz is 0.71 J/g°C.
The best way to balance an equation is to balance one atom at a time.
You start with two Au atoms on the left, so you know the coefficient of Au on the right has to be 2. So at first we get,
Au2S3 + H2 --> 2Au + H2S
Then, notice you have 3 sulfur atoms on the left, so you need three on the right.
Our equation becomes
Au2S3 + H2 --> 2Au + 3H2S
Lastly, we now have six hydrogen atoms on the right, and only two on the left, so we assign a three to the H2 on the left
Au2S3 + 3H2 --> 2Au + 3H2S Is the balanced final equation.
