Explanation:

Balance Chemical Equation:

A balanced chemical equation is that in which the number of the reactant atoms equal to the number of the product atom.

For example if the oxygen at the reactant side is 4, the number of oxygen must be 4 on the product side.

Solution

1. Au₂S₃ + H₂ --------> Au + H₂S

Balance Chemical Equation

1 Au₂S₃ + 3 H₂ --------> 2 Au + 3 H₂S

2. FeS + O₂ ---------> Fe₂O₃ + SO₂

Balance Chemical Equation

4FeS + 7O₂ ---------> 2Fe₂O₃ + 4SO₂

3. NH₃ + O₂ ---------> NO + H₂O

Balance Chemical Equation

4 NH₃ + 5 O₂ ---------> 4 NO + 6 H₂O

4. BaO + H₂O --------> Ba(OH)₂

Balance Chemical Equation

1 BaO + 1 H₂O --------> 1 Ba(OH)₂

Now by balancing all the atoms in equation are equal in reactant and product

Answer from: Quest

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
