What is a rocky part of the shore that sticks out in th ocean

Which compound 2-bromo-2-methylpropane or 2-chloro-2-methylpropane?

AURORKA [14]

The 2-bromo-1-chloro-2-methylpropane molecule contains a total of 14 atom(s). There are 4 Carbon atom(s), 8 Hydrogen atom(s), 1 Chlorine atom(s) and 1 Bromine atom(s). A chemical formula of 2-bromo-1-chloro-2-methylpropane can therefore be written as C4H8BrCl. Is it also commonly called as Propane.

Write the chemical equation for the reaction whose enthalpy change is the standard enthalpy of formation of fructose, C6H12O6(s)

ziro4ka [17]

Answer:

$6 C(s) + 6_{H2}(g) + 3_{O2}(g)$

Explanation:

The chemical equation of the reaction is as follows

According to the question, data provided in the question is shown below:

$C_6H_12O_6$

The C = Carbon and its standard state is Graphite C(s)

The H = Hydrogen and its standard state is $H_2$ (s)

The O = Oxygen and its standard state is $O_2$ (s)

Now the chemical equation for the reaction is

$6 C(s) + 6_{H2}(g) + 3_{O2}(g)$

The reaction of 9.50 g of carbon with Excess O2 Yield 12.8 of CO2. What is the percent yield of this reaction?

Anna [14]

Answer:

Percentage yield = 36.75%

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

C + O₂ —> CO₂

Next, we shall determine the mass of C that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:

Molar mass of C = 12 g/mol

Mass of C from the balanced equation = 1 × 12 = 13 g

Molar mass of CO₂ = 12 + (2×16)

= 12 + 32

= 44 g/mol

Mass of CO₂ from the balanced equation = 1 × 44 = 44 g

SUMMARY:

From the balanced equation above,

12 g of C reacted to produce 44 g of CO₂.

Next, we shall determine the theoretical yield of CO₂. This can be obtained as follow:

From the balanced equation above,

12 g of C reacted to produce 44 g of CO₂.

Therefore, 9.50 g of C will react to produce = (9.50 × 44) / 12 = 34.83 g of CO₂.

Thus, the theoretical yield of CO₂ is 34.83 g.

Finally, we shall determine the percentage yield of the reaction. This can be obtained as follow:

Actual yield of CO₂ = 12.8

Theoretical yield of CO₂ = 34.83 g

Percentage yield =?

Percentage yield = Actual yield / Theoretical yield × 100

Percentage yield = 12.8 / 34.83 × 100

Percentage yield = 1280 / 34.83

Percentage yield = 36.75%

Complete and balance the following:(b) Sb₂O₃(s) + NaOH(aq) →

sammy [17]

Sodium tritioantimonate(III) and water are the products of the reaction between antimony(III) oxide and sodium hydroxide.

Sb2O3(s)+NaOH(aq)→Na3SbO3(aq)+H2O(l)

Balance the reaction from antimony, sodium, then hydrogen and oxygen.

Sb2O3(s)+6NaOH(aq)→2Na3SbO3(aq)+3H2O(l)

The equation is already balanced.

When each element in a chemical reaction has the same number of atoms and total charge on both the reactants and product sides of the equation, the reaction is said to be balanced. In other words, both sides of the reaction have an equal mass and charge of the components.

Because a chemical reaction is simply an arrangement of the atoms of the supplied elements, a chemical equation must be balanced. For the law of conservation of mass to be followed, the chemical equation must be balanced.
