Answer:
A
Explanation:
The sun is larger than the planets in our solar system and has far more mass and gravity than the planets.
Answer:
Standard reduction potential is an intensive property---- True
Reduction takes place at the anode ----- False
The half reaction with the lower standard reduction potential will be at the cathode in a galvanic cell ------false
The half reaction with the higher standard reduction potential will be at the cathode in a galvanic cell ------ True
Explanation:
An intensive property is a property of a substance which is inherent in it and part of its nature. It does not depend on the amount of substance present in the substance. Standard reduction potential is an intensive property.
In a galvanic cell, oxidation takes place at the anode and reduction takes place at the cathode. At the anode, the electrode potential is more negative (an oxidation) while at the cathode the reduction potential is less negative (a reduction).
Answer:
Erosion is the transportation of sediment at the Earth's surface. 4 agents move sediment: Water, Wind, Glaciers, and Mass Wasting (gravity).
Explanation:
Answer:
Explanation:
At 5 s the body has travelled 10 m.
Between 5 s and 10 s, the body reached 30 m.
Distance travelled = 30 m - 10 m = 20 m
Time = 10 s - 5 s = 5 s
You may find the electron diagram of ammonia and the ammonium ion in the attached picture.
Explanation:
Ammonia NH₃ have covalent bonds with the hydrogen atoms in which for each bond one electron comes from nitrogen atom (blue dot) and the other from the hydrogen atom (red dot). You may see that the nitrogen remains with the lone pair of electrons that does not participate in bonding.
Ammonia NH₃ have a basic character and is able to accept a proton H⁺ from an acid to form the ammonium ion NH₄⁺. The fourth bond formed its called a coordinative-covalent bond that is created only with the nitrogen lone pair of electrons (blue dots).
