What type of molecle has water loving and water hating?
regions
How does a molecle differ from an atom?
A molecule is a group of atoms Example: two atoms of Hydrogen + one atom of oxygen = H20 (water)
What causes polarity in a water molecle?
The fact that oxygen has a slightly negative charge and the hydrogens have a slightly positive charge makes the moluecule slightly polar, because its slightly unbalanced.
Why is a water molecle polar?
Water is polar due to the two sets of unbound electron pairs on the oxygen molecule which oppose the positivly charged hydrogen. This causes a dipole, a positive and negative end to the molecule.
Is a diatomic molecle more likely to be held together by a covalent bond or by an ionic bond?
A diatomic molecule is more likely to be held together by a covalent bond. This is because diatomic molecules consist of two atoms of the same element sharing electrons to achieve a stable electron configuration, which is characteristic of covalent bonding. Ionic bonds typically form between atoms of different elements with significantly different electronegativities.
Is a diatomic molecle more likely to be held together by a covalent bond or by an ionic bond And why?
A diatomic molecule is more likely to be held together by a covalent bond. Covalent bonds involve the sharing of electrons between atoms, which is common in diatomic molecules where two atoms of the same element bond together. Ionic bonds involve the transfer of electrons between atoms of different elements, which is not typically observed in diatomic molecules.
What terms do scientist use to describe the chemical process in which oxygen and glucose react to release energy inside body cells?
This is called cellular respiration it is the inverse of photosynthisis the process consists of the converson of a simple sugar (consisting of the compound C6-H12-O6) molecle and six molecules of oxygen (6 O2) and breaking the C6-H12-O6 and 6 O2 into 6 CO2 and 6H2O by deviding the additional six molecules of oxygen into the mix causes the six carbon atoms to combine to their structures froming six carbon dioxide molecules(6 CO2) without the carbon the H12-06 to return to a more natural group water (6 H2O) and with the breakdown oth those molecules energy is releasedrespirationRespiration asGLUCOSE + OXYGEN = ENERGY + CARBON DIOXIDE + WATEROf course, this is known as Aerobic Respiration since Oxygen is involved.Cellular Respiration
Why is heavy water used for heat transfer in nuclear reactor?
Heavy water has the same heat transfer properties as ordinary water, at least in practical terms. It is used in some reactors as the moderator since it is much more efficient at slowing fast neutrons than ordinary water, thus enabling unenriched uranium to be used as the fuel. It is not used to transfer heat to the power producing part of the plant, only as a static tank (called a calandria) full of heavy water as moderator. (See CANDU)
When two or more atoms are joined together what is formed?
Two or more atoms combine or join with each other for the basic chemical property- to retain neutral state.They do so by mutual sharing of their electrons means by forming covalent bond or by complete sharing of their electrons means by electrovalent bonding. By these methods they form a molecle or a compound and become stable in nature.
What is the chemical change of glucose an oxygen into energy?
