Which chemical equation is balanced to show that mass is conserved during the reaction?
A. Na + Cl₂ --> NaCl
B. 2H₂ O₂ --> 2H O + O₂
C. CH₄ + O₂ --> CO₂ + 2H₂ O
D. AgNO₃ + MgCl₂ --> AgCl +MgNO₃
Please Help!!!
So does that mean the answer is D?
Well, since you asked for help, I'll try my best to assist you while throwing in some humor along the way!
Now, let's analyze the options. We're looking for a balanced equation to show that mass is conserved. So, keep in mind that clowns are big fans of conservation, especially when it comes to their fun props!
A. Na + Cl₂ --> NaCl
Hmm, this equation seems a bit short on the clown props. We need to consider that the number of atoms on each side should be the same to balance the equation. So, this one is out of the running.
B. 2H₂ O₂ --> 2H O + O₂
This equation looks promising! Not only does it have an abundant supply of O₂, but it also ensures mass conservation by having the same number of hydrogen and oxygen atoms on both sides. It's like juggling with equal numbers of balls on both hands to maintain balance. Clever!
C. CH₄ + O₂ --> CO₂ + 2H₂ O
Ah, methane! The clown of the hydrocarbon family. But alas, this equation is unbalanced. We have four hydrogen atoms on the left side but only two on the right. It's like wearing oversized shoes on one foot and regular shoes on the other – definitely not a balanced act!
D. AgNO₃ + MgCl₂ --> AgCl +MgNO₃
Let's call this equation the "silver and magnesium circus performance." It's certainly an entertaining combination! But when it comes to balancing equations, it falls short. We have the same number of atoms on both sides, but wait... the charges are all mixed up! It's like a clown juggling while standing on one leg. It's amusing but not quite balanced!
So, my dear friend, the answer to your question is option B. 2H₂ O₂ --> 2H O + O₂. It's a fine example of mass conservation and a well-balanced equation, just like a skilled clown juggling brightly colored balls in perfect harmony! Keep up the great work, and remember, chemistry can be just as fun as a clown show!
To determine which chemical equation is balanced to show that mass is conserved during the reaction, we need to analyze each option and check if the number of atoms on each side of the equation is the same.
A. Na + Cl₂ --> NaCl
- On the left side: 1 sodium (Na) and 2 chlorine (Cl) atoms
- On the right side: 1 sodium (Na) and 1 chlorine (Cl) atom
- This equation is not balanced since the number of chlorine atoms is different on both sides.
B. 2H₂ O₂ --> 2H O + O₂
- On the left side: 4 hydrogen (H) and 4 oxygen (O) atoms
- On the right side: 2 hydrogen (H), 2 oxygen (O), and 1 oxygen (O) atom
- This equation is not balanced since the number of oxygen atoms is different on both sides.
C. CH₄ + O₂ --> CO₂ + 2H₂ O
- On the left side: 1 carbon (C), 4 hydrogen (H), and 2 oxygen (O) atoms
- On the right side: 1 carbon (C), 4 oxygen (O), and 4 hydrogen (H) atoms
- This equation is balanced since the number of atoms on both sides is the same.
D. AgNO₃ + MgCl₂ --> AgCl +MgNO₃
- On the left side: 1 silver (Ag), 1 nitrogen (N), 3 oxygen (O), 1 magnesium (Mg), and 2 chlorine (Cl) atoms
- On the right side: 1 silver (Ag), 1 chlorine (Cl), 1 magnesium (Mg), 1 nitrogen (N), and 3 oxygen (O) atoms
- This equation is balanced since the number of atoms on both sides is the same.
Based on the analysis, the answer is option D. AgNO₃ + MgCl₂ --> AgCl +MgNO₃.
Um, could you help me with that pls?
thank you!!
I will do one:
AgNO₃ + MgCl₂ --> AgCl +Mg(NO₃)2
you copied that incorrectly. now, starting from that, you need two nitrates on the left:
2AgNO₃ + MgCl₂ --> AgCl +Mg(NO₃)2
Nitates are balanced, but silver...
2AgNO₃ + MgCl₂ --> 2AgCl +Mg(NO₃)
now, all are balanced, including silver and chloride.
