Everything in the world gets its energy from the sun so, the cow gets its energy from the grass wich gets energy from the soil wich gets energy from the sun Ect.
Since the Chlorine gained an electron, it became a chlorine ion with +1 charge. Therefore, it is Cl⁺¹.
The formula that would represent an ionic compound that is composed of calcium and iodide ions is CaI2
Explanation
Ionic compound CaI₂ is formed when Calcium form cation ( <em>a positively charged ion</em>) by losing 2 electrons while two iodine atoms form anion ( <em>a negatively charged ion</em>) by gaining one electron each.
When writing down formula of ionic compound, the formula of cation is written first followed by anion formula. therefore Ca is written first followed by I.
The numeric subscript 2 after I(iodine) indicate that 2 atoms of iodine are involved in bonding.
Answer:
The heat capacity of the calorimeter or of the reaction mixture may be used to calculate the amount of heat released/absorbed by the chemical reaction. The amount of heat released or absorbed per gram or more of the reactant can then be calculated from the mass of the reactants.
