Johnny had a balloon filled with.404 g of hydrogen gas. When his lab partner Marisa lit the balloon with a candle on the end of a long stick it burst into a fireball making water. Johnny and Marisa realized that the hydrogen in the balloon reacted with the oxygen in the air to make
water according to the equation:2H2 + O2 --> 2H20
Their teacher asked them to find out how many moles of oxygen were burned and how many moles of water were produced formed.
What is the given? Number: .404 Unit: grams
Substance: hydrogen gas
What are the following moles ratios?
2 H₂ to
O2
2
H₂ to 2
H20
How many grams of oxygen gas were burned up?

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Consider the following unbalanced equation for the combustion of hexane: αc6h14(g)+βo2(g)→γco2(g)+δh2o(g) part a balance the equation. give your answer as an ordered set of numbers α, β, γ, use the least possible integers for the coefficients. α α , β, γ, δ = nothing request answer part b determine how many moles of o2 are required to react completely with 5.6 moles c6h14. express your answer using two significant figures. n n = nothing mol request answer provide feedback
