Answer:
3Ba(OH)₂ + 2H₃PO₄ → Ba₃(PO₄)₂ + 6H₂O
Explanation:
Neutralization reaction:
When an acid and base react they form water and salt.The reaction is called neutralization reaction.
General equation:
HX + BOH → BX + H₂O
From given reaction equations only option C is correct because only this reaction gives salt and water.
Chemical equation:
3Ba(OH)₂ + 2H₃PO₄ → Ba₃(PO₄)₂ + 6H₂O
Barium hydroxide is acting as a base. H₃PO₄ is an acid. Both these reactants react to form salt which is barium phosphate and water.
Other options are incorrect because non of these reaction produced salt and water. So option A is correct.
Answer:
Sink
Explanation:
For a substance to float in water, it must be less dense than water. The density of water is 1 g/cm^3. To find the density of the substance, we can do mass/volume, which in this case is 25g/7cm^3. We see that 
, so the substance would sink.
Thermal expansion because heating something causes the object to expand. <span />
Answer:
Interphase: the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
Mitosis: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). The major purpose of mitosis is for growth and to replace worn out cells.
Cytokinesis: Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... Mitosis and each of the two meiotic divisions result in two separate nuclei contained within a single cell.
Explanation:
I learned about this and it was pretty confusing. But once you start learning this more, you'll definitely get it! :D
Answer:
Energy is stored in the covalent bonds :)
Explanation:
Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy. Except at absolute zero (the coldest temperature it is possible to reach), all molecules move.
