1. Using the Hoffman apparatus for electrolysis, a chemist decomposes 50.5 g of water into its gaseous elements. How many grams

of oxygen gas should she get (theoretical yield)? 2. Liquid sodium reacts with chlorine gas to produce sodium chloride. You want to produce 453 g of sodium chloride. How many grams of chlorine gas are needed? 3. You eat 160.0 g of glucose (a handful of M&M's). If glucose, C6H12O6, reacts with oxygen gas to produce carbon dioxide and water, how many grams of carbon dioxide will you have to exhale?

Use the equation n2 + 3h2=2nh3 if 8.0g N2 react, how many grams of NH3 will be produced
Eduardwww [97]

the balanced equation for the formation of ammonia is

N₂ + 3H₂ ---> 2NH₃

molar ratio of N₂ to NH₃ is 1:2

mass of N₂ reacted is 8.0 g

therefore number of N₂ moles reacted is - 8.0 g / 28 g/mol = 0.286 mol

according to the molar ratio,

1 mol of N₂ will react to give 2 mol of NH₃, assuming nitrogen is the limiting reactant

therefore 0.286 mol of N₂ should give - 2 x 0.286 mol = 0.572 mol of NH₃

therefore mass of NH₃ formed is - 0.572 mol x 17 g/mol = 9.72 g

a mass of 9.72 mol of NH₃ is formed

What form of pollution can lichens be a good indicator of?
Natasha2012 [34]

Answer:

Lichens can be used as air pollution indicators, especially of the concentration of sulphur dioxide in the atmosphere. Lichens are organisms that grow in exposed places such as rocks or tree bark. They need to be very efficient at absorbing water and nutrients to grow there.

Calculate the number of moles found in 3.045x1024 atoms of helium.<br><br> PLS HELP
Kisachek [45]

Explanation:

so for this u have to use this equation where

Moles = number of particle/6.02×10^23

= 3.045 × 10^24/6.02×10^23

= 5.0581

write it to 3 S.F so 5.06 moles

The arrows in the chart below represent phase transitions. Three bars are shown labeled Solid, Liquid, and Gas. They are connect
tester [92]

Answer:

1,2,3

Explanation:

Heat gain implies that heat is absorbed by the system in order to make the stated phase transition possible.

Before a liquid changes to gas, intermolecular forces in the liquid are broken by energy supplied as heat.

Also, transition from solid to liquid requires energy to break intermolecular bonds.

Finally, sublimation requires input of energy in the form of heat.
