Answer:
A. 35Cl1-
Explanation:
Chlorine needs 1 more electron to have full octet thus will take 1 electron and possess a -1 charge.
Answer: 1.87 atm
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 2.50 atm
= final pressure of gas = ?
= initial volume of gas = 26.4 ml
= final volume of gas = 36.2 ml
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:


The new pressure is 1.87 atm by using combined gas law.
The mass and Volume is different even thought they have a similar shape and size
X rays have a lower frequency than microwaves would be the scientific statement.
