Detergents are amphipathic molecules that contain polar or charged hydrophilic groups (heads) at the end of long lipophilic hydrocarbon groups (tails) (Figure 1). They are also known as surfactants because they decrease the surface tension of water.
Answer:

Explanation:
Hello,
In this case, since 454 g are equivalent to 1 pound and 1000 millilitres are equivalent to 1 liter, the required density is computed below by applying the corresponding conversion factor:

Regards.
Answer:
22.44°C will be the final temperature of the water.
Explanation:
Heat lost by tin will be equal to heat gained by the water

Mass of tin = 
Specific heat capacity of tin = 
Initial temperature of the tin = 
Final temperature =
=T

Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water =
=T



On substituting all values:

we get, T = 22.44°C
22.44°C will be the final temperature of the water.
It 6.8 so there you go And this answer is Long because I just need points lol
NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure. This reaction happens during photosynthesis.
