Another type of weathering that attacks rocks is chemical weathering, a process that breaks down rock through chemical changes. The causes of chemical weathering include action of water, oxygen, carbon dioxide, living organisms, and acid rain. Chemical weathering can produce new minerals as it breaks down rock.
Explanation:
It is a physical separation.
Only chemical separation involves the changing of substances and their bondings, which usually involves the use of heat or electricity. Meanwhile, physical changes does not require breaking the bonds of substances or changing a substance to another, common examples of physical separations are such as filtration or distillation.
Since straining pasta from water does not require breaking the pasta or water to other substances, plus heat and electricity is not involved, therefore this is a type of physical separation.
Answer:
pH is 8.52
Explanation:
According to the working in the photo
Answer: the momentum is 6 Kgm/s
Explanation:
M= 5 kg
V= 1.2 m/s
Momentum = MV = 5 x 1.2 = 6 Kgm/s
