If the substance has high melting/boiling point, if it requires high temperature to dissociate into simpler particles, if it's structure is hard and if it conducts heat and electricity quite frequently, then it would be "Ionic compound" otherwise, it will be covalent compound. (compound with covalent bonds).
Substance with ionic bonds, would include... (mentioned in first sentence)
Sample hypothesis : If a substance is solid at room temperature, has a crystalline structure, dissolves easily in water, and conducts electricity well, then it likely contains ionic bonds.
(include in your hypothesis )
high melting and boiling points and therefore solid at room temperature
To help, I drew a diagram. This represents an ionic bond between Na and Cl. Na is giving his single electron to Cl, which is indicated by the arrow, to make Cl full with 8 electrons.
The molecular formula of calcium oxide - CaO The molar mass of CaO - 40 + 16 = 56 g/mol Which means that 1 mol weighs 56 g Therefore 56 g of CaO is - 1 mol Then 89.23 g is equivalent to - 1/56 x 89.23 = 1.6 mol of CaO
When there will be more quantity of co2 in air it will lead to more formation of carbonic acid and it will lower the Ph of rain 5.1 which leads to acid rain
