Phosphoric Acid - The last answer choice
Answer:
Mass = 13.23 g
Explanation:
Given data:
Mass of oxygen = 48.0 g
Mass of propane burn = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 48.0 g/ 32 g/mol
Number of moles = 1.5 mol
now we will compare the moles of propane and oxygen.
O₂ : C₃H₈
5 : 1
1.5 : 1/5×1.5 = 0.3 mol
Mass of propane burn:
Mass = number of moles × molar mass
Mass = 0.3 mol × 44.1 g/mol
Mass = 13.23 g
They both build up to form electricity

Answer:
Explanation:
Electrovalent is a word often associated with chemical bonding in the field of chemistry. It is special type of bond that occurs between metals and non-metals.
These bond types are interatomic interactions occurring between two atoms to ensure that they attain stable configurations.
- This bond type is also known as ionic bonds.
- It occurs between two species with a large electronegative diffference i.e one specie is electropositive and the other highly electronegative.
- The more electropositive specie is metal and it readily loses its valence electrons.
- The electronegative non-metal gains the electrons and becomes negatively charged.
- The electrostatic attraction between the metal and non-metals yields the electrovalent bonds.
