A balloon contains 0.15 moles of co2 gas. how many molecules of co2 are in the balloon?

Oxygen and sulfur have similar chemical properties because both elements have six electrons in their outermost electron shells. Indeed, both oxygen and sulfur form molecules with two hydrogen atoms: water and hydrogen sulfide.

Balance each equation by writing the correct coefficient (put a space in the box if no coefficient is needed). Then, identify the type of reaction taking place. 1. CaCO3 → CaO+CO2 ___CaCO3 → ___CaO+___CO2 is a decomposition reaction. 2.

Roxanne was asked by her teacher to explain why sodium ions (Na) and chlorine ions (CI) combine into sodium chloride (NaCl). Roxanne said it was because chlorine is highly electronegative and sodium has a low ionization energy.
