Answer: There are 4.09×1024 atoms of phosphorus in 3.40 mol copper(II) phosphate.
Answer:
B
Explanation:
weight , w= mg where m is the mass of the object (unit is kg ) and g is the gravitational force acting on the object ( unit is m/s^2 )

Answer:
may involve a change in total mass
involve very high-energy changes
involve changes in nuclides when decay occurs
Explanation:
A nuclear reaction is different from a typical chemical reaction. The reaction occurs within the nucleus and involved nuclear materials.
- Most nuclear reactions involves a change in mass due to the attenuation of the nuclear materials.
- Mass is converted to energy in nuclear reactions.
- Nuclear reactions are usually very high energy processes and they release a significant amount of energy.
- The nuclide changes as new atoms are formed by the process.
Answer:
Polonium
Selenium
Sulfur
Oxygen
Explanation:
If you see in the Table S of the periodic Table there is a column that says First Ionization Energy (kJ/mol) and you can see the numbersof these elements so then you just put it in order
Polonium 812
Selenium 941
Sulfur 1000
Oxygen 1314
They both have a vapor pressure.
