Answer:
1. Proton = electron if the element is not in an ionic state
proton = atomic number
That experiment it's called a MRE bomb. That's why when you add the water to the chemicals in the bottle, it heats up causing the gasses to expand and then the bottle explodes. (It is a very dangerous experiment)
Hope I helped!
- Amber
Answer : Al
Explanation :
- For a given redox reaction there must be an oxidizing agent/(s) and a reducing agent/(s).
- the oxidizing agent is the substance that undergoes reduction process (gaining electrons or loss of oxygen atoms), meanwhile, the reducing agent is the substance that undergoes oxidation process (loss of electrons or gaining of oxygen atoms).
- In the reaction above, the oxidation number of (Al) in AlCl3 is (3+). However, the oxidation number of (Al) in the products is zero because it exists as a single element.
Therefore, changing from (3+) to zero means gaining of (3) electrons to neutralize the previously existing (3) protons on (Al) in AlCl3.
So Al is the oxidizing agent..
Answer:
Ammonia > Urea > Ammonium nitrate > Ammonium sulphate
Explanation:
Percentage by mass of nitrogen in NH3:
Molar mass of NH3= 17 g/mol
Hence % by mass = 14/17 × 100 = 82.35%
% by mass of NH4NO3
Molar mass of NH4NO3 = 80.043 g/mol
Hence; 28/80.043 × 100 = 34.98%
% by mass of (NH4)2SO4;
Molar mass of (NH4)2SO4= 132.14 g/mol
Hence; 28/132.14 × 100 = 21.19%
% by mass of CH4N2O
Molar mass of urea = 60.0553 g/mol
Hence 28/60.0553 × 100 = 46.62%
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.
