KE = (1/2)mv^2
m = 10.0 kg
v = 5.00 m/a
KE = (1/2)(10.0)(5.00)^2 = (1/2)(10.0)(25.0) = 125 J
C. 125 J
Answer:
1 = oxidation
2 = reduction
Explanation:
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
2I- ----> I₂+ 2e⁻
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
F + e⁻ ----> F⁻
Consider the following reactions.
4KI + 2CuCl₂ → 2CuI + I₂ + 4KCl
the oxidation state of copper is changed from +2 to +1 so copper get reduced.
CO + H₂O → CO₂ + H₂
the oxidation state of carbon is +2 on reactant side and on product side it becomes +4 so carbon get oxidized.
Na₂CO₃ + H₃PO₄ → Na₂HPO₄ + CO₂ + H₂O
The oxidation state of carbon on reactant side is +4. while on product side is also +4 so it neither oxidized nor reduced.
H₂S + 2NaOH → Na₂S + 2H₂O
The oxidation sate of sulfur is -2 on reactant side and in product side it is also -2 so it neither oxidized nor reduced.
Answer:
D) There are 33 particles inside of the nucleus and 16 particles outside of the nucleus.
Explanation:
Sulfur has an atomic number of 16. The atomic number represents the number of protons, so sulfur has 16 protons.
This atom of sulfur has a mass number of 33. The mass number is the sum of protons and neutrons. Then, the number of neutrons is 33 - 16 = 17
Sulfur is a neutral atom. Therefore, it has the same number of positive charges (protons) and negative charges (electrons). Thus, sulfur has 16 electrons.
Protons and neutrons are in the nucleus and electrons are outside the nucleus.
Taking all the above into account, the correct answer is:
D) There are 33 particles inside of the nucleus and 16 particles outside of the nucleus.
Answer:
tiny openings called the stomata.
Explanation:
Answer: Option D) All of the above.
Explanation:
The ecosystem is made up of living and non-living component relating with their environment. i.e in an ecosystem, plants and animals relate with the food nutrients, climate and weather conditions, soil structure etc
Thus, all of the conditions: a rise in temperature; natural disaster like flooding; the introduction of a new animal species like a predator will definitely change the previously stable condition of an ecosystem.
