N2(g) + 3H2(g) -> 2NH 3(g)

Chemistry
1 answer:
Nutka1998 [239]4 years ago
5 0

Answer:

None of the options are correct. The correct answer is:

56.67g

Explanation:

N2 + 3H2 —> 2NH3

Molar Mass of NH3 = 14 + (3x1) = 14 + 3 = 17g/mol

Mass of NH3 from the balanced equation = 2 x 17 = 34g

Molar Mass of H2 = 2x1 = 2g/mol

Mass of H2 from the balanced equation = 3 x 2 = 6g

From the equation,

6g of H2 produced 34g of NH3.

Therefore, 10g of H2 will produce = (10 x 34)/6 = 56.67g of NH3

Therefore, 56.67g of NH3 are produced

What is the balanced net precipitation reaction for BaCl2 and KOH?
Dmitrij [34]
BaCl2 reacts with KOH forming KCl which is a salt and Ba(OH)2 which is the precipitate.
The initial UNBALANCED equation expressing this reaction would be:
BaCl2 + KOH .............> KCl + Ba(OH)2
Now, we need to balance this equation:
we have two moles of Cl as reactants and one mole only as product. Therefore, we will multiply the KCl in the product by 2 and the KOH in the reactants by 2.
This will balance the equation as follows:
BaCl2 + 2KOH ......> 2KCl + Ba(OH)2

Noticing this equation, we will find that:
The precipitate was formed due to the combination of the Ba2+ ion with 2 OH- ions as follows:
Ba2+ + OH- ............> Ba(OH)2

n Part B, suppose the tablet was mostly dissolved when some of your solution splashed out of the beaker as CO2 continued to evol
Mandarinka [93]

Answer:

The perceived mass of CO2 would not be affected in large quantities because the splash constitutes small particles of water with sodium bicarbonate that is still reacting. The final calculated mass of sodium bicarbonate in the tablet would be artificially low.

Explanation:

Effervescence is a chemical process that involves the reaction of an acid with a carbonate or sodium bicarbonate, releasing carbon dioxide through a liquid. An example is seen in carbonated beverages, in these the gas that escapes from the liquid is carbon dioxide. The bubbles that are seen are produced by the effervescence of the dissolved gas, which by itself is not visible in its dissolved form.

The combustion of 1 mol ch4 releases 803 kj of energy. how much energy is produced from the combustion of 5.00 mol ch4.
Annette [7]

Answer : The energy produced from the combustion of 5 mole CH_4 is 4015KJ

Solution : Given,

Released energy = 803 KJ

The balanced combustion reaction is,

CH_4+2O_2\rightarrow CO_2+2H_2O

As per the question,

1 mole of CH_4 releases energy = 803 KJ

5 mole of CH_4 produced energy = \frac{5mole}{1mole}\times 803KJ=4015KJ

Therefore, the energy produced from the combustion of 5 mole CH_4 is 4015KJ

Cytokinesis happens differently for plant and animal cells. Both separate cytoplasm between two new daughter cells. However, whi
victus00 [196]

Answer:

animal cell

Explanation:

Cytokinesis -

It refers to the process of cell division, which takes place during mitosis, is known as cytokinesis.

The process of cytokinesis is different for animal cell and plant cell.

  • Where, in case of plant cell, a separation, known as cell plate is formed along the center of the parent cell, which is responsible for the separation of the cells.
  • Whereas, in case of animal cell, the plasma membrane contracts itself along the center, until the two daughter cells are separated from each other.

Hence, from the given information of the question,

The correct answer is animal cell.
