atomic number of elements are the number of protons
in neutral atoms number of protons are equal to number of electrons
electrons are responsible for the chemical bonding in atoms
bonding depends on the number of valence electrons in the outermost shells.
atom A with 11 protons have 11 electrons, electronic configuration is - 2,8,1
atom B with 17 protons have 17 electrons, electron configuration is - 2,8,7
A has 1 valence electron and B has 7 valence electrons
therefore A prefers to give away its one valence electron and have a complete outer shell and B prefers to take in that one electron from A to become a complete octet.
The type of bond is an ionic bond formed by the transfer of electrons from one species to another species
answer is ionic
Water has a definite volume but not a definite shape making the correct answer A.
Charcoal- it's black when you buy it, red when it's burning, and whitish greyish when it's all used up.
Answer:
C₆H₁₂O₆ and O₂ are reactant.
CO₂ and H₂O are products.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Explanation:
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.
Steps involve in anaerobic respiration are:
Glycolysis
Glycolysis is the first step of both aerobic and anaerobic respiration. It involve the breakdown of one glucose molecule into pyruvate and 2ATP.
Fermentation
The second step of anaerobic respiration is fermentation. It involve the fermentation of pyruvate into lactic acid or alcohol depending upon the organism in which it is taking place. There is no ATP produced, however carbon dioxide is released in this step.
A chemical symbol designates an element that belongs to the periodic table.
A chemical formula combines two or more symbols and it represents a chemical compound. We notice that the chemical symbols are followed oftenly by a subscript that represents the mole proprtions of next element.
