PLS HURRY!! Charlie is balancing an equation. She has identified the atoms and counted the number of each in the reactants and products. What would Charlie adjust to make the number of atoms in the reactants the same as the number of atoms in the products? FeCl3 + NH4OH Fe(OH)3 + NH4Cl

CH4 + O2 CO2 + H2O

Fe + H2SO4 Fe2(SO4)3 + H2

PCl5 + H2O HCl + H3PO4

Coefficients

Explanation:

Balancing a chemical equation entails making sure that the number of atoms on the reactant side equates that on the products side. According to this question, Charlie is trying to balance an equation. She has identified and counted the number of each atoms in the reactants and products side.

However, to ensure that the identified atoms are equal on both sides of the equation, Charlie needs to adjust the COEFFICIENTS of necessary molecules/atoms. Coefficients are numbers used to multiply an algebraic term. For example, 2CO2 means coefficient 2 will be used to multiply each atom in the carbon dioxide molecule. Based on this explanation, the balanced forms of the equations in the question are:

1. FeCl3 + 3NH4OH → Fe(OH)3 + 3NH4Cl

2. CH4 + 2O2 → CO2 + 2H2O

3. 2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2

4. PCl5 + 4H2O → 5HCl + H3PO4

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
