Heat travels from hot to cold in order to balance out the temperature. Thus, the heat transfer goes from the hot water to the finger.
If the water was hot enough, it would transfer too much heat, and the finger would get burned.
Answer: Slightly acid, almost neutral.
pOH = -log [OH -] = - log [4.2 x 10^-8] = 7.38
pH + pOH = 14 ==> pH = 14 - pOH = 14 - 7.38 = 6.62.
Remember: 7 is neutral, below 7 is acid. This solution is almost neutral.
Answer:
Mass is 70
Explanation:
Density= Mass divided by Volume
To find the mass you do the opposite of the equation- Volume times the density. Therefore, the mass is 70 because 10 times 7 is 70.
Hope this helps :)
