1. The number of Nin Answer: The number of nitrogen atoms in is 8.Explanation: In the compound , there are two ammonium ions , each containing two nitrogen atoms. Therefore, the total number of nitrogen atoms in the compound is 8.2. How many elements are in the compound Answer: There are 3 elements in the compound .Explanation: The compound contains three different elements: carbon (C), hydrogen (H), and oxygen (O).3. Why is the following chemical equation not balanced. Answer: The chemical equation is not balanced because the number of atoms of each element is not the same on both sides of the equation.Explanation: In the equation , there are 2 hydrogen atoms on the left side and 2 hydrogen atoms on the right side. However, there are 2 oxygen atoms on the left side and only 1 oxygen atom on the right side. To balance the equation, we need to have the same number of atoms of each element on both sides.4. What is a coefficient?Answer: A coefficient is a number placed in front of a chemical formula to indicate the number of molecules or atoms of that substance.Explanation: In a chemical equation, the coefficient is a number that appears in front of a chemical formula. It represents the number of molecules or atoms of that substance involved in the reaction. For example, in the equation , the coefficient 2 in front of indicates that there are two molecules of hydrogen involved in the reaction.5. How many TOTAL atoms are in this compound?Answer: The question does not specify which compound is being referred to.Explanation: Without knowing the specific compound being asked about, it is not possible to determine the total number of atoms in that compound.6. How many Hydrogen are in Answer: There are 8 hydrogen atoms in .Explanation: In the compound , there are 2 hydrogen atoms. Therefore, in , there are 4 molecules of , which means there are a total of 8 hydrogen atoms.
