When sugar is burned, water vapor and carbon dioxide are produced.

Chemistry
1 answer:
Natalija [7]2 years ago
4 0

Answer:

12 carbon, 22 hydrogen, 11 oxygen

Explanation:

Our equation is: Sugar + 12O_2  ⇒  11H_2O + 12CO_2

This is already balanced which means that the number of atoms for each type of element on each side should be the same.

On the right side, there are 11 * 2 = 22 hydrogen atoms, 11 * 1 + 12 * 2 = 11 + 24 = 35 oxygen atoms, and 12 * 1 = 12 carbon atoms.

Currently on the left, there are 12 * 2 = 24 oxygen atoms. That means that sugar must have 11 oxygen atoms to balance it out. In addition, since the left side currently has no hydrogen or carbon atoms, those must belong to the sugar molecule.

Thus, the sugar molecule has 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

The difference between Physical/Chemical properties and Physical/Chemical changes
AfilCa [17]
Physical changes can be reversed and chemical changes can’t be reversed. A physical property is a characteristic which can be identified without changing the substance but to identify a chemical property, you do have to change the substance.

One of the intermediates in the synthesis of glycine from ammonia, carbon dioxide, and methane is aminoacetonitrile, C2H4N2.
mart [117]

Answer:

  • <em>You could expect 3.48 grams of C₂H₄N₂</em>

Explanation:

You must start by stating the chemical equation for the reaction of ammonia, carbon dioxide, and methane to produce aminoaceto nitrile.

1. Word equation:

Ammonia + Carbon dioxide + Methane → Aminoacetonitrile + Water

2. Balanced chemical equation:

       8NH_3+5CO_2+3CH_4\rightarrow 4C_2H_4N_2 +10H_2O

3. Convert the mass of each reactant into number of moles:

<u>Formula:</u>

  • Number of moles = mass in grams/molar mass

<u>2.11g NH₃</u>

  • Number of moles = 2.11g / 17.03g/mol = 0.124 mol NH₃

<u>14.9g CO₂</u>

  • Number of moles = 14.9g/44.01g/mol = 0.339 mol CO₂

<u>1.75g CH₄</u>

  • Number of moles = 1.75g/16.04g/mol = 0.109 mol CH₄

4. Theoretical mol ratio

From the balanced chemical equation, using the coefficientes:

         8molNH_3:5molCO_2:3molCH_4:4molC_2H_4N_2:10molH_2O

5. Limiting reagent

The available amounts of the reactants are:

  • 0.124 mol NH₃
  • 0.339 mol CO₂
  • 0.109 mol CH₄

Fom the theoretical mole ration, to react with 0.124 mol of NH₃ you would need:

  • 0.124molNH₃ × (5molCO₂/8molNH₃) = 0.0775 mol CO₂

Since there are 0.339 moles available, this is in excess.

  • 0.124molNH₃ × (3molCH₄/8molNH₃) =  0.0465mol CO₂

Since there are 0.109 moles available, this is in excess too.

Hence, the limiting reagent is NH₃.

6. Yield

Use the theoretical ratio:

  • 0.124molNH₃ × (4molC₂H₄N₂ / 8molNH₃) = 0.0620 mol C₂H₄N₂

Convert to grams:

  • Mass = number of moles × molar mass
  • 0..0620 mol × 56.068g/mol = 3.48 g of C₂H₄N₂ ← answer

If the ratio of the length of a rectangle to its width is 3 to 2, what is the
borishaifa [10]

Answer:

Length of a rectangle whose width is 4 inches is

<u>6 inches</u>

Explanation:

Ratio of length  to its width is 3 to 2

Let length  = L

Let Width  = B

L: B = 3 : 2 (given)

\frac{L}{B} =\frac{3}{2}

Width ,B = 4

Insert  B in above equation

\frac{L}{B} =\frac{3}{2}

\frac{L}{4} =\frac{3}{2}

cross multiply,

L = \frac{3}{2}\times4

L = 6 inches

Conversion(if required) ,

1 inch = 2.54 cm

6 inch = 2.54 (6)

L = 15.24 cm
