It decreases since a air less balloon is heavier than a Aired balloon
The moles of O2 that are needed to react completely with 35.0 mol C2H2 is 87.5 moles of O2
<u><em>Explanation</em></u>
Write a balanced chemical equation for reaction of between C2H2 and O2
2 C2H2 + 5O2 → 4 CO2 + 2 H2O
if 35.0 moles C2H2 reacted then use the o mole ratio to determine the moles of C2H2
The mole ratio of C2H2 :O2 = 2:5 therefore the moles of O2
= 35 moles x5/2 = 87.5 moles of O2
Answer:
carbon monoxide, CO, can be thought of as having two ordinary covalent bonds between the carbon and the oxygen plus a coordinate bond using a lone pair on the oxygen atom
Explanation:
When the Statue was unveiled in 1886, it was a shiny brown color, like a penny. By 1906, the color had changed to green. The reason the Statue of Liberty changed colors is that the outer surface is covered with hundreds of thin copper sheets. Copper reacts with the air to form a patina or verdigris.
Hope this helps and good luckkk :)
