Which statement is true regarding a chemical reaction?(1 point)
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 check my answer?
These are the correct answers for; Conservation in Chemical Reactions Quick Check for Connexus Students:
1. B. Zn + 2HCI --> H2 + ZnCI2
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 ALL are welcome for the Answers ya Noobs :P
the answers for me as of 11/16/21
1. D the reactants and products have the same number and type of atoms but the atoms may be recombined
2 . B it shows many molecules there are of a particular substance
3. B NaOH+HCI NaCI+H2O
4. D atoms always remain intact during chemical reactions
5. B 4,4
good luck these were correct for me
the right answer for this question is
The total number of atoms does not change, so mass is conserved in the reaction.
:) IS WRONG DO NOT PUT THOSE ANSWERS YOU WILL GET 0 OUT OF 4
Balance reactions Quick Check:
Which statement best represents the law of conservation of matter with regard to chemical reactions?
1. The reactants and products have the same number and type of atoms, but the atoms may 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. Ans: (4, 4) for q's Which numbers balance this equation?
Marie is right!
Is Anonymous right? I’m connexus
@Anonymous is wrong you will get a 1/4
the answers sometimes change around so
1. Zn + 2HCI -> H2+ZnCI2
2. the total amount of atoms dont change
3. 215 amu
4. 76 amu
hope this helps
Guys the reason you all kept getting it wrong is that they mix up the answers every time, the A for one person is the D for another person. Also n has the right answers for connexus ninth grade, thanks for that!
Just to let yall know they switch the places of the answer so don't copy answer for people say if its a, b, or c
@wanst me is correct
@8thGradePro -w-, thanks! I got 100%!!!!! @TURTLE is partially right, but also partially wrong. Trust @8thGradePro!!!! He is correct!!!
@8thGradePro -w- is right thx
omg name is wrong i just got 0 4
@ wasnt me is correct- Connections Academy
@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 the water and salt.3, The total number of atoms does not change, so mass is conserved in the reaction. 4, Zn + 2HCl → H2 + ZnCl2

Can you please tell me the answers for this quick check from questions 1-5 please!
i hate this stuff
who is right
@8thGradePro -w- I was looking to see if someone had the answers so I could check mine and you were the only one I saw with them, so thank you!
