answer:
ionic bonds form between oppositely charged ions
explanation:
- an ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
- ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal.
- a covalent bond involves a pair of electrons being shared between atoms.
Answer:
Latent heat of fusion of the substance is 
Explanation:
Latent heat of fusion denotes amount of energy (heat) per unit mass required to melt a solid material at constant temperature and pressure i.e. at it's melting point
Here amount of heat required = 
Mass of unknown substance being melted = 18.5 kg
So, latent heat of fusion of the substance = (required heat energy to melt)/(mass of the unknown substance) = 
So, latent heat of fusion of the substance is 
Answer:
4
Explanation
Trailing zeros in decimals count as significant figures.
To produce glucose from carbon dioxide, 6 moles of carbon dioxide are required per mole of glucose.
Mass of carbon dioxide required:
