The answer is 20 because in an atom no of protons equal no of electrons
Answer:
The Mouse population will increase: True
The Grass population will increase: False
The Hawk Population will increase: False
The Mouse population will decrease: False
Explanation: This is true because now there is no snake to kill them off. Still, there is the hawk that is there but there will be a general increase in the mouse population
Explanation:
Let us assume that mass of nickel(II) iodide is 2.90 g, volume is 150.ml, and concentration is 0.70 M.
When is added into the solution then it will not affect the concentration.
Moles of =
=
= 0.00928 mol
Moles of =
=
= 0.01856 mol
Molarity of =
=
= 0.124 M
Thus, we can conclude that final molarity of iodide anion in the solution is 0.124 M.
Answer:
D.All chemicals are potentially dangerous
Explanation:
No chemical is toxicologically neutral
Answer:
cellular respiration
Explanation:
All exergonic processes produced in the cell, through which substances oxidize and chemical energy is released, are grouped under the name of cellular respiration, but to break down an organic molecule the cells employ, mainly dehydrogenations that can be carried carried out in the presence or absence of atmospheric O2 oxygen. There are therefore two types of breathing: aerobic respiration and anaerobic respiration. The latter also called fermentation.
Aerobic respiration (oxidative phosphorylation)
- Use molecular O2.
- It degrades glucose to CO2 and H2O
- Exergonic
- Recovers about 50% of chemical energy
- Present in most organisms.
- It uses enzymes located in the mitochondria.
