Determine the limiting reactant in each of the following reactions:

1 answer:

3 0

The reactant in a chemical process known as the limiting reactant controls how much product can be produced. When the limiting reactant is completely used up, the reaction will come to an end.

<h3>Find the limiting reactant ?</h3>

As a result of 1 mol Sb4O6 reacting with 6 mol H2SO4, only 0.1 mol Sb4O6 reacts with 0.6 mol H2SO4, leaving only 0.5 mol H2SO4. This indicates that H2SO4 is the limiting reactant and Sb4O6 is present in excess.
According to your equation, which is balanced, 0.1 mol Sb4O6 should react with 0.6 mol H2SO4, yet there is only 0.5 mol H2SO4 on hand.
Therefore, only.083 mol of Sb4O6 are reacted.
The reactant that is present in the limiting amount—the limiting reactant—determines the extent to which a chemical reaction occurs.
The trick is really quite easy! We employ an augmented matrix to hold the data derived from the balancing equation Sb4O6 + 6H2SO4 --> 2Sb2(SO4)3 + 6H2O.
Although you are provided 0.5 mol of H2SO4, the reaction requires 0.6 mol. Therefore, the limiting reactant is H2SO4.
Only 0.0833 mol of Sb4O6 is required, but you have 0.1 mol. Sb4O6 is therefore the extra reactant.

Answer:

The equation is not correct:

[CH4 + O2 → CO2 + 2H2O]

Explanation:

The chemical formulas for methane, oxygen, and carbon dioxide are correct, but the equation is not balanced, so we really don't know idf the overall reaction is written correctly.

Let's balance the reaction:

CH4 + O2 → CO2

We need to have the same numbers of atoms on both sides.

Count the numbers of each atom:

Element Reactants Products Difference

C 1 1 0 Balanced

H 4 0 -4 XXX!!!!

O 2 2 0 Balanced

The hydrogens aren't showing up in the products. In fact, there is a product missing entirely from the reaction, H2O, water. The basic reaction is:

CH4 + O2 → CO2 + H2O

Now balance this reaction:

Element Reactants Products Difference

C 1 1 0 Balanced

H 4 2 -2 Hmmmm . . .

O 2 3 1 Uh = oh . . .

This reaction is not possible - there are either too many or too few element atoms (the "Difference").

We can adjust the coefficients for each of the molecules to balanced the equation. This is a bit tricky, but it consists of trying some coefficients that would make things balance. Only whole number coefficients are allowed in the final answer, although fractions might be used in the process to help find the whole numbers.

We need 2 H2O molecules to account for the 4 hydrogens on a single methane molecule

Step 1: CH4 + O2 → CO2 + 2H2O

That leads to:

Element Reactants Products Difference

C 1 1 0 Balanced

H 4 4 0 Balanced

O 2 4 2 Darn

We need more oxygen atoms, so:

Step 2: CH4 + 2O2 → CO2 + 2H2O

This leads to:

Element Reactants Products Difference

C 1 1 0 Balanced

H 4 4 0 Balanced

O 4 4 0 Balanced

This is a balanced reaction, and the correct chemical equation.

Determine the molar mass of a compound that has a density of 0.1633 g/L at STP. (show work)

hodyreva [135]

Answer:

M.Mass = 3.66 g/mol

Data Given:

M.Mass = M = ??

Density = d = 0.1633 g/L

Temperature = T = 273.15 K (Standard)

Pressure = P = 1 atm (standard)

Solution:

Let us suppose that the gas is an ideal gas. Therefore, we will apply Ideal Gas equation i.e.

P V = n R T ---- (1)

Also, we know that;

Moles = n = mass / M.Mass

Or, n = m / M

Substituting n in Eq. 1.

P V = m/M R T --- (2)

Rearranging Eq.2 i.e.

P M = m/V R T --- (3)

As,

Mass / Volume = m/V = Density = d

So, Eq. 3 can be written as,

P M = d R T

Solving for M.Mass i.e.

M = d R T / P

Putting values,

M = 0.1633 g/L × 0.08205 L.atm.K⁻¹.mol⁻¹ × 273.15 K / 1 atm

M = 3.66 g/mol

astra-53 [7]

Answer:

- Fossils are an important part of the study of human evolution When a plant or animal dies its body is acted upon by various forces of nature like wind, air; With time body decomposes and gets covered by layers of soil in millions of years Due to increasing pressure with every layer of soil getting added it creates an impression of the body while it further decays, Even it is acted upon by hot temperature inside So even after millions of years of extinction of a species we can study about it looking at its impression in soil known as Fossil one of the ways is.
