Answer: The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

Answer:
Option B
Covalent Bonding
Explanation:
Covalent bonds in C2H5OH are formed between the carbon and hydrogen atoms, where there are shared electron pairs.
This is a weak form of attraction that holds the C2H5OH molecule together, and can easily be broken by a polar solvent such as water.
In order for water to be able to dissolve the C2H5OH molecule, it must break the covalent bonding present in the molecule
Reactivity metal is when a group of metal elements form recreation using acids, water.
Answer:
Ionic bonds transfer electrons and covalent bonds share electrons.
Explanation:
Ionic bonds tend to transfer electrons completely. Take NaCl for example.
Cl has 7 valence electrons.
Na has 1 valence electron.
To stabilize themselves, either with a full 8 shells or full outer shell, Cl wants 1 electron and Na wants to lose 1 electron. So when NaCl forms, Na donates its electron to Cl.
In a covalent bond, the electrons are shared. Water can be used as an example. The electrons in water usually are around the oxygen, but sometimes it is around the hydrogens.
