Answer:
Explanation:
as we know that 1dm3 =1000cm3
therefore x dm3 =120 cm3
1000X =1*120
X dm3 =120/1000=0.12
so 120 cm3 =0.12 dm3
now the number of moles of carbon dioxide at RTP is
moles =given volume(dm3)/standard volume at RTP
moles=0.12dm3/24
moles =5*10^-3
4 is correct. Since gases are made of rapidly moving molecules with a relatively high amount of kinetic energy, the molecules have a hard time coming together to form a liquid. You must lower their kinetic energy with a low temperature and force the molecules together with high pressure.
Answer:
yes, but its better to drink water
Explanation:
Answer:
C. It is reactive because it must gain two electrons to have a full outermost energy level.
Step-by-step explanation:
The electron configuration of this element ends in 2s²2p⁴.
A filled energy level would end in 2s²2p⁶.
The element will be reactive, because it must gain electrons to have a full energy level, and it needs two more electrons to do this.
