The answer is to heat the water up to increase the rate that which it dissolves
Answer:
52.5 g
Explanation:
Density= mass/volume
Rearranging the equation gives us m= d(V)
m= d(V)
m= (10.5 grams/cm^3)(5 cm^3)
m= 52.5 g
Exposure to high energy waves can be helpful to cells by damaging DNA in cells, meaning if somebody were to have cancer cells it breaks down the bad cells and it can shrink tumor. It can be harmful by damaging skin cells, which we need as our first line of defense. Meaning, it could cause skin cancer. Hope this helped!
FeO + Al -> AlO + Fe
As you can see, this type of reaction would lead to be a Single Placement (or Replacement) reaction!
Hope this helps! Best wishes!
