A student does an experiment using barium chloride and magnesium sulfate. The student adds 10.0 g of barium chloride with 5.8 g of magnesium sulfate in water. From the chemical reaction, 4.6 g of magnesium chloride are formed along with 11.2 g of barium sulfate as a solid. Why does this chemical reaction demonstrate the Law of Conservation of Mass? Please help me with this if you can Scie​

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
