You can put a known amount sodium into some sort of time release mechanism such as a pill made from soluble material. Then you can place the sodium into a calorimeter with a known mass of water and record the temperature change the water undergoes during the reaction. Then you can use the equation q(water)=m(water)c(water)ΔT to find the amount of heat absorbed by the water. since the amount of heat absorbed by the water is the amount of heat released from the sodium, q(sodium)=-q(water). Than you can use the equation q(sodium)=m(sodium)c(sodium)ΔT and solve for c(sodium)
I hope this helps and feel free to ask about anything that was unclear in the comments.
Answer:
oceanic formation is the right answer.
Explanation:
this os becoz they slide a past each other and do not rub against each other
It is not directly over a flame because it depends on the substance you might not want to heat it too much.you never know what could happen
Your answer would be D, single replacement
H is 4*10^6 M , OH is 2.5*10^-9 M
