Define ionization energy and explain why the second aisle and ionization energy of the element is higher than its ionization energy
The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom. By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase.
The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.
H(g) -----> H+(g) + e- deltaHo = -1312.0 kJ/mol
Answer:
The candle ran out of oxygen
Explanation:
There is a concept known as the fire triangle, the three things present for a fire to start and burn. Heat, Oxygen, Fuel. Take any one of the three away and the fire goes out. Pour water on a fire, and it absorbs the heat, put a jar over it, it removes the oxygen, stop adding wood to a campfire it goes out.
Answer:
An element is a substance that cannot be split out into simpler substance by chemical means
A compound i is a substance consisting atoms of 2 or more different elements and these atoms are chemically joined together
Explanation:
Answer:
Order of the cycle:
Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.
Explanation:
<u>Step -1:</u>
Carbon dioxide is taken in by plants during photosynthesis.
<u>Step -4;</u>
The animal eats a plant and uses its carbohydrates for energy.
<u>Step - 3</u>
The animal releases the carbon dioxide back into the atmosphere during respiration.
<u>Step -2</u>
The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in.
Therefore, order of the cycle is Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.
