Correct answer choice is :
B) Chemistry
Explanation:
Advanced titanium-based compounds have been also used for some years for extremely stressed femoral segment stalks. Both metal samples present a higher impedance to pitting, crack, and galvanic corrosion, stress corrosion weakening and corrosion burnout than polished stainless steel of comparatively low power properties. For this purpose, the low element power of hip prostheses made of the recent stuff is paid for by a larger cross-section of the prosthetic stem, this depending on the geometric situations of the femur.
Hydrogen have only one electron and easily form compounds with other elements that is the reason hydrogen is chemically unstable
The salt dissolves in the water and the sand will gather at the bottom.
Chemical reactions involve the breaking of bonds and forming new bonds. All chemical reactions involves forming of new substances. For this, stuation, it is evident that a chemical reaction occur because a precipitate formed. Therefore the correct answer is stated in statement 1.
