Answer:
electrolysis of brine
Explanation:
Rock salt deposits are usually mined; occasionally water is pumped down, and brine which contain 25 percent of sodium chloride is found
so d brine is electrolyzed to produce chlorine
Answer:
50 because it’s a ratio problem
Explanation:
Answer:
T = 246 K
Explanation:
Given that,
Number of moles, n = 0.750 mol
The volume of the cylinder, V = 6850 mL = 6.85 L
Pressure of the gas, P = 2.21 atm
We need to find the temperature of the gas stored in the cylinder. We know that,
PV= nRT
Where
R is gas constant
T is temperature
So,

or
T = 246 K
So, the temperature of the gas is equal to 246 K.
Answer:
Define a problem, form a hypothesis, gather experimental data, form a conclusion
I would say that it would probably be: The Sun pulls on Earth as Earth moves around the sun.
Sorry if I'm wrong <3
