because they are both in one group :)

Answer 25

Thank you:)

Answer 26

you r welcome :)

Answer 27

Which of the following equations is balanced?
A. Na2SO4(aq) + 2CaCl2(aq) CaSO4(s) + NaCl(aq)
B. Na2SO4(aq) + CaCl2(aq) CaSO4(s) + 2NaCl(aq)
C. 2Na2SO4(aq) + CaCl2(aq) CaSO4(s) + 2NaCl(aq)
D. Na2SO4(aq) + CaCl2(aq) CaSO4(s) + NaCl(aq)

Answer 28

reaction is balanced when number of something on left side is equal to number of that same something on the right side

Answer 29

Then would it be B?

Answer 30

bingo :)

Answer 31

Thank you!:)

Answer 32

you are welcome :))

Answer 33

What is a redox reaction?

B. A reaction in which an element changes phases when going from reactant to product
C. A reaction in which an element in one molecule is traded for an element in another
D. A reaction in which the number of protons changes between the reactant and product

Answer 34

redox reaction is when both oxidation and reduction happens in one reaction

Answer 35

Then A?

Answer 36

bingo :)
