Which statement is true about a chemical reaction? (1 mark) A. Even if the total number of atoms changes, mass may not be conserved in the reaction.
B. The total number of atoms changes, so mass is conserved in the reaction.
C. The total number of atoms does not change, so mass is conserved in the reaction.
D. Even if the total number of atoms does not change, mass may not be conserved in the reaction.
I got C. Can someone verify my answer? These are the correct answers for; Quick check of conservation in chemical reactions for Connexus students:
1. B. Zn + 2HCI –> H2 + ZnCl2
2. D. The total number of atoms does not change, so mass is conserved in the reaction.
3.C.215 amu
4.B.76 amu
You are ALL welcome for answers ya Noobs 😛 the correct answer to this question is
The total number of atoms does not change, so mass is conserved in the reaction. the answers for me on 11/16/21
1. D reactants and products have the same number and type of atoms but atoms can be recombined
2 . B it shows that there are many molecules of a particular substance
3. B NaOH+HCl NaCl+H2O
4. D atoms always remain intact during chemical reactions
5.B 4.4
good luck, they were correct for me 🙂 IT IS WRONG DO NOT PUT THESE ANSWERS YOU WILL GET 0 OUT OF 4 Marie is right! Is Anonymous right? I’m connected @Anonymous is wrong, you’ll get a 1/4 Balance reactions Quick Check:
Which statement best represents the law of conservation of matter for chemical reactions?
1. Reactants and products have the same number and type of atoms, but atoms can be recombined.
2.It shows how many molecules there are of a particular substance.
3. NaOH + HCl → NaCl + H2O
4. Atoms always remain intact during chemical reactions.
5. Answer: (4, 4) for q Which numbers balance this equation? my name is wrong, I just received 0 4 @8thGradePro -w-, thanks! I got 100%!!!!! @TURTLE is partially right, but also partially wrong. Trust @8thGradePro!!!! he is right!!! @8thGradePro -w- is right thank you @8thGradePro -w- is right!!!!!
Thanks for connexus 9th grade are 1,30,2,Find the mass of an acid and a base. Combine them to produce water and a salt. Find the mass of water and salt.3, The total number of atoms does not change, so mass is conserved in the reaction. 4, Zn + 2HCl → H2 + ZnCl2 Guys, the reason you are all wrong is that they mix up the answers every time, the A for one person is the D for another person. Also na the correct answers for ninth grade connexus, thanks for that! Quick check of reagents against products
According to the law of conservation of mass, which statement about chemical reactions is always true? (1 mark)
Can you please tell me the answers for this quick check of questions 1-5 please! who’s right @8thGradePro -w- I was looking to see if anyone had the answers so I could check mine and you were the only one I saw with them, so thanks! n is correct 4/4 TRUST 8TH GRADE PRO These are the correct answers for; Quick check of conservation in chemical reactions for Connexus students:
1. B. Zn + 2HCI –> H2 + ZnCl2
2. D. The total number of atoms does not change, so mass is conserved in the reaction.
3.C.215 amu
4. B. 76 amu These are the correct answers for; Quick check of conservation in chemical reactions for Connexus students:
1. B. Zn + 2HCI –> H2 + ZnCl2
2. D. The total number of atoms does not change, so mass is conserved in the reaction.
3.C.215 amu

100% correct. I just did the test, do ctrl+f and paste the answer into the thing to get 100%. It will be in the upper left corner.
See you later @ that wasn’t me is correct – Connections Academy answers sometimes change so
1. Zn + 2HCI -> H2+ZnCl2
2. the total amount of atoms does not change
3. 215 amu
4.76am
Hope this helps Just to let you know they change places in the answer so don’t copy the answer for people to say if it’s a, b or c
@wanst is correct to me All of these answers are correct, trust me. i hate this stuff it looks good @wanst me its ok
however question 1 was D. The reactants and products have the same number and type of atoms, and the atoms are NOT recombined D
