Place 10 in the intersection. Put 4x - 10 in the "math only" field Put 5x - 10 in the "science only" field then 4x-10 + 5x-10 + 10 + 15 = 95 9x = 90 x = 10 and acc to question 4x= 4 * 10 = 40 3x= 3 * 10 = 30

So do you think that H2SO4 is the better choice? Or shall I stick with CaCO3

Chemistry
sorry the rest of the choices are b. Co2 C. HClO4 D HI e H2SO4 I think its a.. since it displaces the ions
