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:
C they are moving away from each other
Explanation:
Answer is: adenosine triphosphate.
ATP is made of three components: the triphosphate (P), the sugar ribose and a nitrogenous base (adenine).
ATP is short for adenosine triphosphate
Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released.
Here we have to determine the formula of the ionic compound formed between a and iodine.
The ionic compounds are those which remains in ionic state in its solution phase. The formula of the compound aF₃ which reveals the element a is trivalent i.e. a³⁺. It will remain in ionic state as follows: aF₃ → a³⁺ + 3F⁻.
As the element a is trivalent thus with iodine also it will combine like fluorine (as both belongs to the same halogen group). The formula of the compound will be aI₃ and it will be ionic in nature. The ions will be aI₃ → a³⁺ + 3I⁻.
Thus the formula of the ionic compound between a and iodine is determined.
