Answer:
mountains-a large natural elevation of the earth's surface rising abruptly from the surrounding level; a large steep hill.
Explanation:
Answer:
Group 1 or akali metals have the greatest metallic property.
Group 17 has the lowest metallic character.
C. As you move from right to lefton the periodic table, metallic character increases which is the ability to lose electrons. Ionization energy decrease as we move from right to left on the periodic table.
Explanation:
Akali metals in group 1 have the greatest metallic property and they are the most reactive metals. Francium metal on the group has the most metallic characteristics. It is rare and very radioactive. Group 17 has the lowest metallic character. This is because while moving across the period, the number of electrons in the outermost shell increases. This make it difficult for atoms to leave see electrons and become electropositive . Group 17 has the highest tendency of accepting electrons.
Ionization energy is the energy use to remove electron from an atom in gaseous stage. Ionization energy decrease as we move from right to left on the periodic table and metallic character increases as we move from right to left on the periodic table.
When water freezes to form ice, the molecules would be vibrating in place rather than moving round. It is a result of a decrease in the kinetic energy of the molecules of water. It is said that the temperature and the kinetic energy of the molecules is directly proportional which means that when temperature is increased, the kinetic energy of the molecules would increase as well making the molecules move around. However for this case, when we day the system is cooled then it means the temperature is decreased which would result to the decrease of the kinetic energy of the molecules.
Answer:
c Acid + base = conjugate base + conjugate acid
Explanation:
In a Bronsted-Lowry acid-base reaction, the original acid gives up its proton and becomes a conjugate base. In like manner, the original base accepts a proton and becomes a conjugate acid. For every acid, there is a conjugate base and for every base, there is a conjugate acid:
HA ⇄ H⁺ + A⁻
acid conjugate base
B + H⁺ ⇄ HB⁺
base conjugate acid
