Are these balanced and are my products correct?
3HNO3(aq)+Al(OH)3(s) = Al(NO3)3+3H2O(l)
Na2CO3(s)+H2SO4(aq) = H2O(l)+CO2(g)+Na2SO4(aq)
I just wanted someone to look this over and see if I did it right
yes, and yes.
To determine if these chemical equations are balanced and if your products are correct, we need to check the number of atoms on both sides of the chemical equations. Here's how you can do it:
1. Balancing equation 1: 3HNO3(aq) + Al(OH)3(s) -> Al(NO3)3 + 3H2O(l)
To balance the number of atoms on both sides, start with the elements that appear in multiple compounds:
- Nitrogen (N): On the left side, we have 3 nitrogen atoms from 3HNO3. On the right side, there are 3 nitrogen atoms from Al(NO3)3. This is balanced.
- Oxygen (O): On the left side, we have 9 oxygen atoms from 3HNO3. On the right side, we have 12 oxygen atoms from Al(NO3)3 and 3H2O. To balance it, add a coefficient of 4 in front of H2O: 3HNO3 + Al(OH)3 -> Al(NO3)3 + 4H2O.
Now, for the second equation:
2. Balancing equation 2: Na2CO3(s) + H2SO4(aq) -> H2O(l) + CO2(g) + Na2SO4(aq)
- Sodium (Na): On the left side, we have 2 sodium atoms from Na2CO3. On the right side, there are also 2 sodium atoms from Na2SO4. This is balanced.
- Carbon (C): On the left side, we have 1 carbon atom from Na2CO3. On the right side of the equation, there is no carbon atom. To balance it, add a coefficient of 1 in front of CO2: Na2CO3 + H2SO4 -> H2O + 1CO2 + Na2SO4.
- Hydrogen (H): On the left side, we have 2 hydrogen atoms from H2SO4. On the right side, we have 2 hydrogen atoms from H2O. This is balanced.
- Sulfur (S): On the left side, we have 1 sulfur atom from H2SO4. On the right side, we have 1 sulfur atom from Na2SO4. This is balanced.
- Oxygen (O): On the left side, we have 4 oxygen atoms from H2SO4. On the right side, there are 1 oxygen atom from H2O and 2 oxygen atoms from CO2, giving a total of 3 oxygen atoms. To balance it, add a coefficient of 3 in front of H2SO4: Na2CO3 + 3H2SO4 -> 3H2O + CO2 + Na2SO4.
After balancing both equations, they should now be in a balanced form. Double-check the coefficients to ensure that the number of atoms on both sides of each equation is equal.
Now, to verify if your products are correct, consult a trusted source or use a chemical equation calculator to check the balanced equations against the actual products formed during the reaction.
