Answer:
It would take 13 minutes.
Explanation:
The temperature decreases at a linear rate, meaning that we can describe the process by using the following formula:
Where T₂ is the final temperature, T₀ is the initial temperature; and t is the elapsed time in minutes.
We input the data given by the problem:
- 0 °C = 26 °C - 2°C/min * t
And solve for t:
Answer:

Explanation:
Answer:
In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such as formic and lactic acids are miscible in water, but higher molecular mass organic acids, such as benzoic acid, are insoluble in molecular (neutral) form.
will this help?
Answer:
No.
Explanation:
No. There is 1 atom of Ca on the left and 2 Ca's on the right and 2 OH's on the left and 4 on the right.
The balanced equation is:
4OH- + 2Ca2+ ----> 2Ca(OH)2.
