The combustion of a sample of butane, C4H10 (lighter fluid), produced 2.46 grams of water.
avanturin [10]

a. 0.137

b. 0.0274

c. 1.5892 g

d. 0.1781

e. 5.6992 g

<h3>Further explanation</h3>

Given

Reaction

2 C4H10 + 13O2 -------> 8CO2 + 10H2O

2.46 g of water

Required

moles and mass

Solution

a. moles of water :

2.46 g : 18 g/mol = 0.137

b. moles of butane :

= 2/10 x mol water

= 2/10 x 0.137

= 0.0274

c. mass of butane :

= 0.0274 x 58 g/mol

= 1.5892 g

d. moles of oxygen :

= 13/2 x mol butane

= 13/2 x 0.0274

= 0.1781

e. mass of oxygen :

= 0.1781 x 32 g/mol

= 5.6992 g

A chemical reaction yields 3 moles of lithium hydroxide (LiOH). How many grams of
grin007 [14]

72g

Explanation:

Given parameters:

Number of moles of LiOH = 3moles

Unknown:

Mass of LiOH = ?

Solution:

A mole of  substance is a unit used to make quantitative measures in chemistry.

It is the amount of substance that contains the avogadro's number of particles.

The mole is related to mass using the expression below;

    Mass of a substance = number of moles x molar mass

Molar mass of LiOH = 7 + 16 + 1 = 24g/mol

 Mass of LiOH = 3 x 24 = 72g

What mass of H2SO4 is contained in 60.00 mL of a 5.85 M solution of sulfuric acid
strojnjashka [21]

First, we have to calculate the number of moles of H2SO4 in the solution:

V=60 mL = 0.06 L

c=5.85 mol/L

n=V×c=0.06×5.85=0.351 mol

Then we need to find the molar mass of H2SO4:

2×Ar(H) + Ar(S) + 4×Ar(O) =

=2 + 32 + 64 = 98 g/mol

Finally, we need to find the mass of H2SO4:

m=0.351 × 98 = 34.398 g

Use the equation to answer the question
vaieri [72.5K]

CH4 + 2O2→CO2 + 2H2O

Explanation:

CH4 + O2→CO2 + H2O

First look at the C atoms. At first glance they are balanced with 1 C on each side.

Now look at the H atoms. They are not balanced. There are 4 H atoms on the left side and 2 H atoms on the right. Place a coefficient of 2 in front of the H2O. We now have 4 H atoms on both sides.

CH4 + O2→CO2 + 2H2O

Now look at the O atoms. They are not balanced. There are 2 O atoms on the left side and 4 on the right. Place a coefficient of 2 in front of the O2. We now have 4 O atoms on both sides.

CH4 + 2O2→CO2 + 2H2O

The equation is now balanced. Each side has 1 C atom, 4 H atoms, and 4 O atoms.

Which statement best explains why sugar water can be easily separated?
VladimirAG [237]

Answer:

Sand has a strong non-polar covalent connection, that prevents water to break it down.

Explanation:

Sand being composed of quartz and small particulars of minerals can only be dissolved in hot acids, unlikd sugar which can easily be broken down by water, due to the large magnetic molecular propery of water and the ability to evolve sugar in an Intermolecular manner.
