Answer:40g of D
Explanation:
Law of conservation of matter:
Matter can neither be created nor be destroyed but can change from one form to another.
The total of the reactants must be equal to that of the product.
A+B=>C+D
50g+30=40g+D
80g=40g+D
D=80-40
D=40g

Answer:
1. atomic #
2.The sugar-water is a homogeneous mixture
Explanation:
1. However, if it has positive ion, then this electron number will go down (ie +2 charge means two electrons have been lost, so the electron/atomic number will go down by two) and vice versa.
2.Sugar dissolves and is spread throughout the glass of water. The sand sinks to the bottom. The sugar-water is a homogenous mixture while the sand-water is a heterogeneous mixture. Both are mixtures, but only the sugar-water can also be called a solution.
