Answer:
a- Uno de carbono y dos de azufre
Explanation:
El compuesto formado entre el carbono y el azufre es CS2.
El carbono forma dos enlaces dobles con dos átomos de azufre.
Por lo tanto, el compuesto contiene un átomo de carbono y dos átomos de azufre.
Explain whether this is a chemical or physical change, and why. does it involve elements, compounds, mixtures, or pure substances?
If the process involves a chemical reaction then surely it is a chemical change where new bonds are being formed from the collision of the reactants.
Describe how many atoms are involved before and after. what do you notice about the number of atoms?
From the balanced chemical reaction, we see that we need 1 mol of N2 gas and 3 mol of H2 in order to form 2 mol of NH3.
Answer:
Explanation:
Any system within the Earth system is considered an open system. Because energy flows freely into and out of systems, all systems respond to inputs and, as a result, have outputs.
