Answer:
what is the net ionic equation
H2SO4(aq) + Cal2(aq) → CaSO4(s) + 2Hl(aq)?
A. H++ SO42- + Ca2+ + 21 → CaSO4 + H+ +1-
B. 2H+ + S042- + Ca2+ + 21° → Ca2+ + SO42- + 2H+ + 21
C. S042- + Ca2+ → CaSO4,
D. 2H+ + SO42- + Ca2+ + 2I- → CaSO4 + 2H+ + 2I-
cancel the spectator ion that is the ions which does not take place in the reaction
for this case is 2 H^+ and 2 i^-
d answer is correct that help
Answer:
=7.89013× 10^47 moles of zinc
Explanation:
1 atom contains 6.023×10^23 moles.
1.31×10^24 atoms of zinc contain6.023×10^24×1.31×10^.24
You would get four moles of magnesium nitrate :) you would have to
“ ?molesmg(oh)2 = 8molmg(no3)2 x molmg(oh)2 / 2molhno3 = 4 moles of magnesium nitrate :))) hopefully this helps! <3
i believe its true bc ik for sure air is a homogenous mixture
