True. Covalent bonds involve sharing electrons to create a full valence shell.
Answer:
0.3808
Explanation:
number of moles,n=Conc.XVol.
hence 0.85X0.448
1) Calcium carbonate contains 40.0% calcium by weight.
M(CaCO₃)=100.1 g/mol
M(Ca)=40.1 g/mol
w(Ca)=40.1/100.1=0.400 (40.0%)!
2) Mass fraction of this is excessive data.
3) The solution is:
m(Ca)=1.2 g
m(CaCO₃)=M(CaCO₃)*m(Ca)/M(Ca)
m(CaCO₃)=100.1g/mol*1.2g/40.1g/mol=3.0 g
Answer:
45 meters
Explanation:
If it takes the slug 20 minutes to travel 15 meters, you multiply the 15 by three to get the distance for 60 minutes.
It is reflected ir transmitted depending on what the material is. The color that something appears is actually the color that it reflects or transmits and not the color that it absorbs. I hope this helps.
