I'd say it's single replacement/displacement
Answer:
Tug of War
An object sinking in water
Kicking a ball
Answer:
C. I, III , IV
Explanation:
As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
As the size of atom increases the ionization energy from top to bottom also decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.
Answer:
SnS
Explanation:
Tin(II) sulfide is a chemical compound of tin and sulfur. The chemical formula is SnS. Its natural occurrence concerns herzenbergite, a rare mineral.
Answer:
Pyruvate, FAD, Acetyl CoA, Fumarate, Oxaloacetate
Explanation:
In the first half of the citric acid cycle pyruvate is oxidized,yielding a pair of electrons that reduce a molecule of NAD to NADH .Succinate is oxidized to fumarate using FAD as electron acceptor.A 2 carbon group from acetyl CoA enters the cycle.A second oxidation produces fumarate and 2 electrons.Malate is oxidized yielding a 4 carbon molecule of oxaloacetate and two electrons.
