It's an alkali metal so one, they sit on the very first of the column in the periodic table :DDDD
Answer:
85.5 mmHg is the pressure of the gas sample when the valve is opened.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in container A = 165 mmHg
= final pressure of gas = ?
= initial volume of gas in container A= 
= final volume of gas = 135 mL + 117 mL = 252 mL
= initial temperature of gas in container A = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
85.5 mmHg is the pressure of the gas sample when the valve is opened.
I believe its because oxygen and carbon cant be sperated
Question: Would an earthquake support the principle of uniformitarianism or the principle of catastrophism? Explain.
Answer: Catastrophism was the theory that the Earth had largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope. This was in contrast to uniformitarianism (sometimes described as gradualism), in which slow incremental changes, such as erosion, created all the Earth's geological features.
Hope this helps, have a good day. c;
Answer:
C. Distance and mass.
Explanation:
Objects that have greater mass have more force of gravity between them.
