D. I or Iodine
This is because they are both in the same periodic family (the halogens) and thus the number of valence electrons are the same
Answer:
Explanation:
Tools, instruments, apparatus are very key to research works carried out in the laboratory. The more sophisticated they become, the more efficiency they provide in making ground breaking researches.
Over the years, technological advancement has afforded scientists with new way of achieving precision and accuracy in their procedures by developing cutting edge facitlities. These equipment can help carry out better experiment and make observations simple and easy to do.
Answer: 3 moles solute x 1 dm^3/0.60 moles solute = 5 dm^3
Explanation:
The reaction formula of this is C3H8 + 5O2 --> 3CO2 + 4H2O. The ratio of mole number of C3H8 and O2 is 1:5. 0.025g equals to 0.025/44.1=0.00057 mole. So the mass of O2 is 0.00057*5*32=0.0912 g.
Well ask yourself why don't we count it in moles and you should get your answer.
