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
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.
Answer : The energy produced from the combustion of 5 mole 
is 
Solution : Given,
Released energy = 803 KJ
The balanced combustion reaction is,
As per the question,
1 mole of releases energy = 803 KJ
5 mole of produced energy = 
Therefore, the energy produced from the combustion of 5 mole is
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.
