hello i have 3 quesions on chemistry. 1. When 12.259 g of a compound containing only copper and oxygen was decomposed it produced 2.410 g of oxygen. How many grams of copper were in the compound? 2.A second sample of the compound in question 5 above released 1.734 g of oxygen when it was decomposed. How many grams of copper were in this second sample. (Use the information in question 1 as well). 3.Taking the same compound of question 1, how many grams of the compound would be required to produce 3.082 g of oxygen? Please answer all the three questions... Thanks
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
