Answer:
double covalent bond
Explanation:
Double covalent bond -
It is the type of interaction observed between two species , which share the electrons in order to attain stability , is referred to as covalent bond.
The shared electrons are referred to as the bonding pairs or the shared pairs .
Stability and completion of the octet is the driving force for the formation covalent bond.
The molecules of the organic compound usually shows this type bonding .
A double covalent bond is the one which have four shared pair of electrons , i.e. two covalent bonds.
Hence , from the question,
Oxygen is capable to show double covalent bond .
Answer:
The temperature in degress Celsius is 52.25°C
Explanation:
According the equation:
The temperature is:
°C
D. Nonpolar dissolves in polar
Answer:
The coefficient in a balanced chemical equation indicates the mole ratio of both reactants and products.
Explanation:
For example lets consider the reation between Hydrogen and Oxygen to form water:
2H2 + O2 ----------------------- 2H2O
In this reaction, the coefficients of the balanced reaction can be transformed to Mole ratio according to Avogadro's Law which states that at standard temperature and pressure, equal volume of gases contain the same number of moles.
So the mole ratio for the above equation is the ratio of the coefficient:
2moles : 1 mole : 2 moles
I think it’s the third option but I’m not entirely sure
