How do you balance CO2 plus H2 to yield CH3OH?
To balance the equation CO2 + H2 ➝ CH3OH, you would need to first balance the carbon atoms, then the hydrogen atoms, and finally the oxygen atoms. In this case, the balanced equation would be: CO2 + 3H2 ➝ CH3OH + H2O.
Why is the reaction SO2 H2O H2SO2 not balanced?
This reaction is not balanced because the number of sulphur atoms is not the same on each side of the equation. There is one sulfur atom on the left (SO2) but two sulfur atoms on the right (H2SO3). Balancing the equation would involve changing the coefficient in front of one or more of the compounds.
Why is the equation H2 O2 -- H20 not balanced?
The equation H2 + O2 -> H2O is not balanced because the number of oxygen atoms is not equal on both sides. In this equation, there are two oxygen atoms on the left side (1 in H2O and 1 in O2) and only one oxygen atom on the right side (in H2O). Balancing the equation would require adjusting the coefficients to ensure that there is the same number of each type of atom on both sides.
How do you write a balanced equation for the reaction of sulfur with the following metals to form solids that you can take to be ionic when the anion is S2?
To write a balanced equation for sulfur reacting with metals to form ionic compounds with S2- ions, you would need to consider the valency of the metal involved. For example, with sodium (Na), the balanced equation would be: 2Na + S → Na2S. The coefficients are adjusted to balance the charge on each side of the equation.
If 75 g of oxygen react how many grams of aluminum are required?
The balanced chemical equation for the reaction between aluminum and oxygen is 4Al + 3O2 → 2Al2O3. Using the stoichiometry of the equation, you would need 50 g of aluminum to react with 75 g of oxygen, since the molar ratio between Al and O2 is 4:3.
How would you know if an equation is balanced?
all of the atoms on one side equal the atoms on the other
Is this equation balanced CaO HCL CaCl2 H2o Yes thank you What I need to know is the number of atoms in the reactants of the chemical equation?
The equation given is not balanced. To determine the number of atoms in the reactants, you need to balance the equation first. Once balanced, you can count the total number of atoms on each side of the equation.
What coefficiant would al have in the balanced equation?
The coefficient of Al in a balanced chemical equation would depend on the specific reaction being considered. It is determined by ensuring that the number of atoms of each element is the same on both sides of the equation.
What is this unbalanced chemical equation what is the coefficient for aluminum oxide (al2o3) when the equation is balanced?
To balance the unbalanced chemical equation involving aluminum oxide (Al₂O₃), you need to ensure that the number of atoms of each element is the same on both sides of the equation. Without the specific equation provided, I can't give the exact coefficient for Al₂O₃. However, in typical reactions involving Al₂O₃, the coefficient could vary based on the reactants and products involved. Once the equation is balanced, you would determine the coefficient for Al₂O₃ from that specific context.
How many atoms of hydrogen appear on each side of the equation?
To determine the number of hydrogen atoms on each side of the equation, you would need to balance the equation first. Once the equation is balanced, count the number of hydrogen atoms on both the reactant and product sides to compare. The number of hydrogen atoms should be the same on both sides of the balanced equation.
What is the theoretical yield of aluminum oxide if 3.40mol of aluminum metal is exposed to 2.85mol of oxygen?
The balanced chemical equation for the reaction between aluminum and oxygen to form aluminum oxide is: 4Al + 3O2 → 2Al2O3. From the balanced equation, we can see that 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Therefore, if 3.40 mol of aluminum and 2.85 mol of oxygen are reacted, the limiting reactant is oxygen. Thus, 3.40 mol of aluminum would theoretically produce 1.90 mol of aluminum oxide.
Why is balanced a balanced chemical equation needed to solve al stoichiometry?
A balanced chemical equation is needed to ensure that the number of atoms of each element is the same on both the reactant and product sides. This balance allows for accurate stoichiometric calculations involving the quantities of reactants and products in a chemical reaction. Without a balanced equation, the stoichiometric calculations would be incorrect.
How do you balance CO2 plus H2 to yield CH3OH?
To balance the equation CO2 + H2 ➝ CH3OH, you would need to first balance the carbon atoms, then the hydrogen atoms, and finally the oxygen atoms. In this case, the balanced equation would be: CO2 + 3H2 ➝ CH3OH + H2O.
What is the formula for a compound containing aluminum atoms and also three times as many chlorine atoms as there are aluminum atoms?
The formula would be AlCl3, which is aluminum chloride.
Why must a chemical equation be balanced before you can determine the mole ratio?
A balanced chemical equation ensures that the law of conservation of mass is followed, meaning the same number of atoms of each element are present on both sides of the equation. Without a balanced equation, the mole ratio would be inaccurate because the amounts of substances would not be properly accounted for in the reaction.
Is SiCl plus Mg---MgCl2 plus Si Balanced?
The chemical equation SiCl + Mg → MgCl2 + Si is not balanced. To balance it, you would need to adjust the coefficients to ensure that the number of atoms of each element is the same on both sides of the equation.
How many atoms does oxygen have on the left hand side of an equation?
In a chemical equation, the number of atoms on each side must be balanced according to the Law of Conservation of Mass. For oxygen, the number of atoms can vary depending on the specific compound involved in the reaction. To determine the number of oxygen atoms on the left-hand side of an equation, you would need to look at the stoichiometry of the reaction being described.
