Answer:
B. Density
Explanation:
The remaining three affect surface currents.
<u>Continental deflections</u>: The continents that rise above sea level cause the surface currents to change direction.
<u>Coriolis effect</u>: This is the deflection of wind and ocean currents due to the Earth’s rotation.
<u>Winds</u>: These are the wind patterns that circulate the warm and cold air around the globe.
The drug only works by chemical reaction. The drug reacts with a target molecule which for example could be inhibiting an enzyme involved in the bio-synthetic pathway of cholesterol (statin, cholesterol drug) or cell wall synthesis of a bacterium (antibiotic).
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.
When Rutherford exposed nitrogen gas to alpha particles, some of the alpha particles were absorbed by the nitrogen nuclei.
A equation for the alpha particle bombardment is as follows:
¹⁴₇N+⁴₂He---->¹⁷₈O+¹₁H
So, as it can be seen from the equation that some of the alpha particles are absorbed by nitrogen nuclei.
