Ans 1. Both
Ans 2. Once inside plants, carbon moves through food chains, where organisms become nutrients including herbivores, carnivores and ultimately, decomposers. Once buried in the soil, carbon can be converted into fossil fuels over long periods of time and then also reenter the atmosphere by combustion. The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law
Ans 3. Most of the chemical energy needed for life is stored in organic compounds as bonds between carbon atoms and other atoms. The law of conservation of energy states that energy can not be created or destroyed. Thus, just like matter energy is also conserved in the process.

Answer:
Explanation:
Avogadro's number, 6.022 * 1023 is the number of things in one mole. The question indicates that there is 1 mole of H2. Thus there are 6.022 * 1023 molecules of H2
Answer:
2S + 3O 2 --->2SO 3 synthesis
Explanation:
2Na + 2H 2O -->2NaOH + H 2 single replacement
2S + 3O 2 --->2SO 3 synthesis
2H 2O 2 --->2H 2O + O 2 decomposition
CaCl 2 + F 2 ---> CaF 2 + Cl 2 single replacement
Answer:
2FeBr3 + 3Na2S ➡️ Fe2S3 + 6NaBr
Susan should follow PEMDAS,
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction,
So, the first step should be, to solve the equation in the parentheses.
I hope this helps!
