Could you help me complete these equations. I can balance them after
NaOH (aq) + HI (aq) --->
LiHCO3 (aq) + HI (aq) --->
HCl (aq) + NaHCO3 (aq) -->
Na2CO3 (aq) + HBr (aq) -->
HNO3 (aq) + KHCO3 (aq) -->
HBr (aq) + NH3 (aq) --->
HNO3 (aq) + Ca(OH)2 (aq--->
The general equation is
acid + base = salt + water.
Carbonates + acid = salt + H2CO3 which the breaks down further to H2O and CO2.
The HBr + NH3 ==> a salt of NH4Br(aq).
Sure! To balance these equations, you'll need to follow a few general steps:
Step 1: Write down the chemical formula of each compound involved in the reaction.
Step 2: Identify the elements present in each compound.
Step 3: Count the number of atoms of each element on both sides of the equation.
Step 4: Adjust the coefficients (numbers in front of the compounds) to balance the number of atoms for each element.
Let's go through each equation one by one:
1. NaOH (aq) + HI (aq) -->
Start by balancing the sodium (Na) and iodine (I) atoms:
NaOH (aq) + HI (aq) → NaI (aq) + H2O (l)
2. LiHCO3 (aq) + HI (aq) -->
This equation is already balanced.
3. HCl (aq) + NaHCO3 (aq) -->
Start by balancing the hydrogen (H) and chlorine (Cl) atoms, then balance the sodium (Na), carbon (C), and oxygen (O) atoms:
HCl (aq) + NaHCO3 (aq) → NaCl (aq) + H2CO3 (aq)
4. Na2CO3 (aq) + HBr (aq) -->
Start by balancing the sodium (Na) atoms, then balance the hydrogen (H) and bromine (Br) atoms:
2Na2CO3 (aq) + 2HBr (aq) → 2NaBr (aq) + H2O (l) + CO2 (g)
5. HNO3 (aq) + KHCO3 (aq) -->
Start by balancing the hydrogen (H) and nitrogen (N) atoms, then balance the potassium (K), carbon (C), and oxygen (O) atoms:
HNO3 (aq) + KHCO3 (aq) → KNO3 (aq) + H2O (l) + CO2 (g)
6. HBr (aq) + NH3 (aq) -->
This equation is already balanced.
7. HNO3 (aq) + Ca(OH)2 (aq) -->
Start by balancing the hydrogen (H) and oxygen (O) atoms, then balance the nitrogen (N) and calcium (Ca) atoms:
2HNO3 (aq) + Ca(OH)2 (aq) → Ca(NO3)2 (aq) + H2O (l)
Please note that these balanced equations may differ based on the state of the compounds (aqueous, liquid, gas) and the specific conditions of the reaction.
