List the total number of each type of atoms in the following reactants.
A) 2HCL + Ca(OH)2
= 6 hydrogen, 2 carbon, 2 lithium, 2 calsium, 4 oxygen
B) 2Na3PO3 + 3Ca(NO3)2
This one is a bit more complicated. May any chemistry teacher show me how to do this. Thank you very much in advance.
HCl Hydrogen, and chlorine: NOT carbon, lithium.
Ca(OH)2 one calcium, 2 oxygen, two hydrogen
B. 6 sodium 2 Phosphrous, 6 oxygen, 3 calcium, 6 nitrogen, 12 oxygen
Thank you very much sir
Sure! I can help you with that.
To determine the total number of each type of atom in a chemical reaction, you need to count the number of each element on both sides of the equation.
Let's analyze the given reaction: 2Na3PO3 + 3Ca(NO3)2
On the left side, we have:
- 2 moles of Na3PO3
- 3 moles of Ca(NO3)2
Let's break down the compounds and count the atoms.
In Na3PO3, we have:
- 2 moles * 3 atoms of sodium (Na) = 6 atoms of sodium (Na)
- 2 moles * 1 atom of phosphorus (P) = 2 atoms of phosphorus (P)
- 2 moles * 3 atoms of oxygen (O) = 6 atoms of oxygen (O)
In Ca(NO3)2, we have:
- 3 moles * 1 atom of calcium (Ca) = 3 atoms of calcium (Ca)
- 3 moles * 2 atoms of nitrogen (N) = 6 atoms of nitrogen (N)
- 3 moles * 6 atoms of oxygen (O) = 18 atoms of oxygen (O)
Adding up the total number of atoms on the left side, we have:
- 6 atoms of sodium (Na)
- 2 atoms of phosphorus (P)
- 24 atoms of oxygen (O)
- 3 atoms of calcium (Ca)
- 6 atoms of nitrogen (N)
Therefore, on the left side, the total number of each type of atom is:
- 6 atoms of sodium (Na)
- 2 atoms of phosphorus (P)
- 24 atoms of oxygen (O)
- 3 atoms of calcium (Ca)
- 6 atoms of nitrogen (N)
I hope this helps! Let me know if you have any other questions.
To determine the total number of each type of atom in a chemical equation, you need to know the chemical formulas of the reactants and their coefficients (numbers in front of the formulas).
Let's break down the equation B: 2Na3PO3 + 3Ca(NO3)2
Step 1: Write down the chemical formulas of the reactants.
Na3PO3: This means there are 3 sodium (Na) atoms, 1 phosphorus (P) atom, and 3 oxygen (O) atoms.
Ca(NO3)2: This means there are 1 calcium (Ca) atom, 2 nitrogen (N) atoms, and 6 oxygen (O) atoms.
Step 2: Multiply the coefficients by the number of each atom in each formula.
2Na3PO3:
- 2 (coefficient) * 3 (Na atoms) = 6 sodium atoms
- 2 (coefficient) * 1 (P atom) = 2 phosphorus atoms
- 2 (coefficient) * 3 (O atoms) = 6 oxygen atoms
3Ca(NO3)2:
- 3 (coefficient) * 1 (Ca atom) = 3 calcium atoms
- 3 (coefficient) * 2 (N atoms) = 6 nitrogen atoms
- 3 (coefficient) * 6 (O atoms) = 18 oxygen atoms
Step 3: Add up the total number of each type of atom from both reactants.
- Sodium (Na): 6 atoms (from Na3PO3)
- Phosphorus (P): 2 atoms (from Na3PO3)
- Calcium (Ca): 3 atoms (from Ca(NO3)2)
- Nitrogen (N): 6 atoms (from Ca(NO3)2)
- Oxygen (O): 6 atoms (from Na3PO3) + 18 atoms (from Ca(NO3)2) = 24 atoms
So, the total number of each type of atom in the reactants 2Na3PO3 + 3Ca(NO3)2 is:
- Sodium (Na): 6
- Phosphorus (P): 2
- Calcium (Ca): 3
- Nitrogen (N): 6
- Oxygen (O): 24
