balance the following equations and write an equation for the mole to mole relationship and the mass relationship
a. Na + H2O > NaOH + H2
b. HCl + KOH > KCl + H2O
2Na + 2H2O > 2NaOH + H2
2 mols Na = 2 mols H2O = 2 mols NaOH = 1 mol H2.
You can plug in the masses.
The second one is done the same way.
2Na + 2H2O > 2NaOH + H2
How do I plug in the masses. The question is find the mass relationship
Sodium Chloride is decomposed into the elements sodium and chlorine by means of electrical energy. How many grams of chlorine gas can be obtained from 2.5 moles of sodium chloride?
I think I answered this above for you.
I think I answered this for you above.
To balance the given equations, we need to ensure that there is an equal number of atoms on both sides of the equation. Let's solve them step by step:
a. Na + H2O > NaOH + H2
To balance the equation, we need to ensure that both sides have an equal number of atoms for each element.
First, count the number of atoms for each element on both sides:
On the left side:
- Sodium (Na): 1 atom
- Hydrogen (H): 2 atoms
- Oxygen (O): 1 atom
On the right side:
- Sodium (Na): 1 atom
- Hydrogen (H): 2 atoms
- Oxygen (O): 1 atom
Since the number of atoms of each element is already balanced, this equation does not require any further balancing.
Now, let's write the equation for the mole-to-mole relationship and the mass relationship:
The mole-to-mole relationship for this equation can be derived from the coefficients of the balanced equation. In this case, the coefficients in front of each compound represent the ratio of moles.
The balanced equation: 2Na + 2H2O → 2NaOH + H2
From this equation, we can derive the following mole-to-mole relationships:
- 2 moles of Na react with 2 moles of H2O to produce 2 moles of NaOH and 1 mole of H2.
Regarding the mass relationship, you would need to know the molar masses of each compound to calculate the specific mass relationship. However, we can provide a general mass relationship based on the mole-to-mole relationship if we assume that all the compounds are in their simplest form:
- 2 moles of Na react with 2 moles of H2O to produce 2 moles of NaOH and 1 mole of H2. From this, we can infer that the mass relationship is 2:2:2:1 for Na:H2O:NaOH:H2, respectively.
b. HCl + KOH > KCl + H2O
Let's balance the equation by ensuring an equal number of atoms on both sides:
On the left side:
- Hydrogen (H): 1 atom
- Chlorine (Cl): 1 atom
- Potassium (K): 1 atom
- Oxygen (O): 1 atom
On the right side:
- Chlorine (Cl): 1 atom
- Potassium (K): 1 atom
- Hydrogen (H): 2 atoms
- Oxygen (O): 1 atom
To balance the equation, we can add a coefficient in front of HCl on the left side:
HCl + KOH > KCl + H2O
1HCl + KOH > KCl + H2O
Now, the atom count is balanced:
On the left side:
- Hydrogen (H): 1 atom
- Chlorine (Cl): 1 atom
- Potassium (K): 1 atom
- Oxygen (O): 1 atom
On the right side:
- Chlorine (Cl): 1 atom
- Potassium (K): 1 atom
- Hydrogen (H): 2 atoms
- Oxygen (O): 1 atom
The equation is now balanced.
For the mole-to-mole relationship and the mass relationship, the coefficients in front of each compound represent the ratio of moles. In this balanced equation, we have:
The balanced equation: HCl + KOH > KCl + H2O
From this equation, we can derive the following mole-to-mole relationships and general mass relationship:
- 1 mole of HCl reacts with 1 mole of KOH to produce 1 mole of KCl and 1 mole of H2O.
- The mass relationship depends on the molar masses of each compound involved.
