Answer: 37 protons, 48 neutrons, and 36 electrons.
Explanation: I assume "Revision" is Rubidium. It is atomic number 37, so it has 37 protons. It's atomic mass is 85, so it has an average of (85-37) = 48 neutrons. It has a charge of +1, so one electron of the original 37 has left.
Answer:
0.228 L is the volume that the gas occupies after it is driedand stored at STP.
Explanation:
Pressure of the wet gas = 
1 atm = 760 Torr
Pressure of water vapor = p = 0.0372 atm
Pressure of gas = 
Volume of wet gas = 
1 mL = 0.001 L
Temperature of the wet gas = 
Pressure of dry gas at STP = 
Temperature of the dry gas at STP ,
Volume of dry gas at STP = 
Using combined gas law:
0.228 L is the volume that the gas occupies after it is driedand stored at STP.
Because the reaction occurs between a metal and non metal
CL=2,8,7
C
Answer:
1) False
2) there are equal amounts of rectants and products
Explanation:
1) When dynamic equilibrium is achieved. the rate of forward and backward reaction they are the same, that is to say, two opposite reactions occur at the same rate, keeping the concentrations constant over time. Different to say the rate of the ractions go to zero.
2) A chemical equilibium exists when what is produce in quantities is equal to what reacts.
So the correct answer is the literal (d).
