In a reaction, 5.07 g of iron are reacted with 11.2 grams of copper (II) sulfate in the following single replacement reaction. How many grams of copper would be produced? 3 Fe + 4 CuSO4 --> Fe3(SO4)4 + 4 Cu

the f

last graph i believe

step-by-step explanation:

worked it out i believe

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
