who is right
:) IS WRONG DO NOT PUT THOSE ANSWERS YOU WILL GET 0 OUT OF 4
the right answer for this question is
The total number of atoms does not change, so mass is conserved in the reaction.
The total number of atoms does not change, so mass is conserved in the reaction.
Marie is right!
Is Anonymous right? I’m connexus
@Anonymous is wrong you will get a 1/4

@8thGradePro -w-, thanks! I got 100%!!!!! @TURTLE is partially right, but also partially wrong. Trust @8thGradePro!!!! He is correct!!!
@8thGradePro -w- is right thx
@8thGradePro -w- is right!!!!!
Thanks
Thanks
@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!

omg name is wrong i just got 0 4
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
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!
n is correct 4/4

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

@wanst me is correct
however question 1. was D.The reactants and products have the same number and type of atoms, and the atoms are NOT recombined

@ wasnt me is correct- Connections Academy
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

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
