Answer:
2As + 6NaOH =2Na3AsO3 +3H2
Explanation:
2As + 6e- = 2As³ ,this is an oxidation reaction
6H¹ +6e- =6H⁰ ,this is reduction process
the above reaction exhibit a redox redox reaction As acts as a reducing agent while NaOH acts as an oxidizing agent.
Answer:
3.6g
Explanation:
2 moles of water gives 1 mole of oxygen
2(h2o)=1(o2)
2(molar mass of h2o)=1(molar mass of oxygen molecule)
2(18)=1(16×2)
36=32
3.6=x
cross multiply
3.6×32=36× x
115.2=36x
x=115.2÷36
x=3.6g
I hope this helps in some way. I forgot to mention that the question states they want to find THE NUMBER OF MOLES for H2O. Yherefore, you would want mol of H2O on top.
Bohr model of an atom illustrates a nucleus with electrons circling around it. This is a useful model for understanding atoms because this clarified that atoms are actually composed of three particles: protons, neutrons and electrons. The first two are located at the center part of an atom (nucleus), while electrons are located at the outer part. Valence electrons of an atom are also vital in the creation of different chemical compounds.
