Consider a reaction in which hydrogen (H2) and oxygen (O2) react to form water (H2O). By mass, the mixture of reactants is 1 par

t hydrogen and 6 parts oxygen. Write the chemical reaction showing reactant and products including any leftover oxygen or hydrogen. Calculate the equivalence ratio for this reaction.

Answer:

equivalence ratio= 0.08333

Explanation:

The balanced stoichoimetric equation tells us the amount of hydrogen in moles required to react with a specific amount of oxygen in moles to produce water. The Balanced equation of the reaction is shown

2H_{2}+O_{2}  → 2 H_{2}O

this means 2 parts of Hydrogen will react with one part of oxgen to produce 2parts of water as shown above

in the question, 1 part of hydrogen was made to react with 6parts of oxygen. which means comparing with the balanced equation, oxygen is in excess as only \frac{1}{2} part of oxygen will react with 1part of hydrogen. the equation is shown below

1H_{2}+\frac{1}{2} O_{2}  → 1 H_{2}O +\frac{11}{2}O_{2}  

The equivalence ratio is the ratio of actual fuel to air ratio to stoichiometric fuel to air ratio and is calculated as follows:

actual fuel/air ratio = parts of fuel/parts of air

                               =\frac{1}{6}

stoichiometric fuel/air ratio = \frac{2}{1}

equivalence ratio = \frac{actual fuel/air ratio}{stoichiometric fuel/air ratio }

                             =\frac{\frac{1}{6} }{\frac{2}{1} }

                             = 0.08333

Have a great day Jershaun9358

Decreasing the saturation of the fatty acid chains on a particular type of phospholipid would result in the formation of _____.
LUCKY_DIMON [66]

Answer:

The correct answer is "more fluid bilayers".

Explanation:

A fatty acid is a biomolecule of lipidic nature formed by a long hydrocarbon chain of different lengths at the end of which there is a carboxyl group.

The wall of the gallbladder consists of three main layers of tissue: The mucosa covers the wall of the gallbladder. The muscular layer of smooth muscle. The serosa, which is the outer layer.

By decreasing the saturation of the fatty acid chains in phospholipids, the bile layers would reduce their thickness and become more fluid.

Have a nice day!

Use the reaction N2(g) + 3H2(g) 2NH3(g) to answer the following questions
kumpel [21]

Answer:

Explanation:

a ) If N₂(g) and 3H₂(g) is added to the system , 2 moles of additional  ammonia will be produced .

b ) If pressure is decreased , less amount of ammonia will be formed, because forward reaction reduces the pressure. So, reaction will take place in reverse direction.

c ) Keq = [ NH₃ ] ² / [ N₂ ] [ H₂]³

d ) Substituting the given values in the equation ,

Keq = [ 6M ] ² / [ 3M] [ 4M]³

= 36 / 3 x 64 M⁻²

= 18.75 x 10⁻² M⁻² .

What is the mass (in grams) of 6.78 moles of dinitrogen pentoxide
WINSTONCH [101]
<h2>Hello!</h2>

The answer is:

There are 732.24 grams of Dinitrogen Pentoxide  N_{2}O_{5} in 6.78 moles of the same compound.

<h2>Why?</h2>

The dinitrogen pentoxide, or nitrogen pentoxide, is a rare salt that consists of anion and cations, and it's an important compound when preparing some kinds of explosives.

So, to answer the question, first,  need to look for the molecular formula of the dinitrogen pentoxide, then, use it to calculate the mass in gram of 6.78 moles of the same compound.

The dinitrogen pentoxide formula is:

N_{2}O_{5}

Where, the molar mass of each element are:

N=\frac{14g}{mol}

O=\frac{16g}{mol}

Calculating the molar mass  of the compound, we have:

N_{2}O_{5}=2*(\frac{14g}{mol})+5*(\frac{16g}{mol})

N_{2}O_{5}=(\frac{28g}{mol})+(\frac{80g}{mol})=(\frac{108g}{mol}

Now, calculating what is the mass of 6.78 of N_{2}O_{5}, we have:

mass=moles*MolarMass=6.78mol(N_{2}O_{5})*\frac{108g}{mol}=732.24g(N_{2}O_{5})

So, there are 732.24 grams of Dinitrogen Pentoxide  N_{2}O_{5} in 6.78 moles of the same compound.

Have a nice day!

Answer:

25.)Intrusive rocks have a coarse grained texture. Extrusive Igneous Rocks: ... Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture. Hot gas bubbles are often trapped in the quenched lava, forming a bubbly, vesicular texture.
