6.6 g
Explanation:
The mole ration between CaCO₃and CO₂ is 1 : 1
Because the molar mass of CaCO₃ is 100.0869 g/mol the amount of moles used in this chemical reaction is;
15/ 100
This will be similar to the moles of CO₂
Because the molar mass of CO₂ is 44g, then well multiply by the moles;
15/100 * 44
= 6.6 g
1. 45.0 L H2S ( 1 mol / 22.4 L) ( 3 mol O2 / 2 mol H2S ) ( 22.4 L / 1 mol ) = 67.5 L O2 needed

3.</span>In an ionic bond, oppositely charged ions are held together by the electronic force of attraction that exists between oppositely charged particles. In the ionic compound, anions and cations are present in a ratio that causes the total charge on the compound to be zero. Sodium phosphide, Na3 P, has three sodium ions for each phosphide ion. This ratio insures a zero total charge given the charges on the two individual ions (Na = 1+, P = 3-).
An unstable atom would be the answer.
Answer:
Graduated cylinder vs Beaker
Both graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are better for stirring and mixing liquids
