Answer:
around it's own acid and around the sun
Answer : The value of reaction quotient Q is, 0.498
Explanation:
Reaction quotient (Q) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.
The given balanced chemical reaction is,
The expression for reaction quotient will be :
![Q=\frac{[CO][H_2]}{[H_2O]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BCO%5D%5BH_2%5D%7D%7B%5BH_2O%5D%7D)
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
Now we have to calculate the concentration of 
and,
and,
Now put all the given values in the above expression, we get:
Thus, the value of reaction quotient Q is, 0.498

what do you need help with i cant see it
Explanation:
Answer:
This question is incomplete
Explanation:
This question is incomplete because the result of the described experiment would have better determined the type of scientific explanation to profer. However, the type of material that will preserve the relative hotness or temperature of the hot coffee for the longest time will be a material than can resist heat transfer. These materials tend to keep hot substances hot by not allowing the heat of the coffee to be conducted or pass through it. These materials are mostly insulators or made by placing an insulator between two heat conductors.
Generally, heat is usually transferred from a region of higher concentration to a region of lower concentration, hence when the heat is denied of this transfer, the heat will remain trapped in the "heat-donor" substance (in this case the hot coffee). Thus, the material chosen (A, B or C) will be the material that resists heat transfer the most based on the explanation above.
