Answer:CAST!!!!!!!!!!!!!!!
Explanation:
The temperature for the reaction is calculated as follows
delta H/ delta S
delta H=-70 Kj
delta S =-0.300 kj/k
temperature is therefore = -70kj/-0.300kj/k =233.33 K
We know that the equation for density is:
where D is the density, m is the mass in grams, and V is the volume.
Given two of the variables, we can then solve for density:
Therefore, we now know that the density of the gasoline is 0.833g/mL.
Answer:
Commonly, Overband Magnets are used to separate steel cans and Eddy Current Separators are used to expel and separate aluminium cans; The Aluminium Cans are discarded into general waste, which is then processed.
Explanation:
PH=-log[H⁺]
pH=-log(1.87×10⁻¹³)
pH=12.72
I hope this helps. Let me know if anything is unclear.
